Selective nonoperative versus operative management of liver gunshot injuries: a retrospective cohort study.

Experience accumulated over the last decades suggests nonoperative management (NOM) of civilian gunshot liver injuries can be safely applied in selected cases. This study aims to compare the outcomes of selective NOM versus operative management (OM) of patients sustaining gunshot wounds (GSW) to the liver. A registry-based retrospective cohort analysis was performed for the period of 2008 to 2016 in a Brazilian trauma referral. Patients aged 16-80 years sustaining civilian GSW to right-sided abdominal quadrants and liver injury were included. Baseline data, vital signs, grade of liver injury, associated injuries, injury severity scores, blood transfusion requirements, liver- and non-liver-related complications, length-of-stay (LOS), and mortality were retrieved from individual registries. A total of 54 patients were eligible for analysis, of which 37 underwent NOM and 17 underwent OM. The median age was 25 years and all were male. No statistically significant differences were observed between groups regarding patients' demographics, injury scores, grade of liver injury and associated lesions. NOM patients tended to sustain higher-grade injuries (86.5% vs 64.7%; p = 0.08), and failure of conservative management was recorded in two (5.4%) cases. The rate of complications was 48% with no between-group statistically significant difference. Blood transfusion requirements were significantly higher in the OM group (58.8% vs 21.6%; p = 0.012). The median LOS was seven days. No deaths were recorded. Patients with liver GSW who are haemodynamically stable and without peritonitis are candidates for NOM. In this study, NOM was safe and effective even in high-grade injuries.

Decoding definitions of major bleeding in retrospective observational studies on direct oral anticoagulants for atrial fibrillation: a targeted literature review

Abstract Background Major bleeding is an adverse event associated with using direct oral anticoagulants (DOACs) for treatment of atrial fibrillation (AF). Incidence rates of major bleeding vary notably between randomised controlled trials (RCTs) and real-world evidence (RWE) studies. This may be attributable to inconsistent major bleeding definitions across RWE studies. RCTs commonly use the International Society on Thrombosis and Haemostasis (ISTH) major bleeding definition, including fatal bleeding, critical area/organ bleeding, bleeding requiring a blood transfusion of 2 or more units, and/or reductions in haemoglobin. These parameters may be absent in RWE studies, leading to utilisation of proxy definitions. Thus, the components used to define major bleeding in RWE studies remain unclear. Purpose To examine major bleeding definitions via a targeted literature review of retrospective observational studies on patients with AF receiving DOACs in routine clinical practice. Methods Studies of patients with AF receiving DOACs that were published between 2012 and 2022 were identified using keywords and MeSH terms in PubMed. Retrospective observational studies were screened for inclusion by title and abstract, and subsequently by full text. Articles were assessed for the types of databases and DOAC therapies studied. Components of major bleeding definitions were recorded and compared across database types. Results Of 328 articles screened, 18 retrospective observational studies were included in this analysis. The most common data sources were claims data (n = 10), followed by electronic medical records (n = 4), and registry data (n = 4). Across studies, major bleeding incidence rates varied from 0.59 to 11.4 events per 100 person-years. Of the 6 components of major bleeding definitions identified, requiring hospitalisation (n = 12) was the most frequent (Figure), though is not essential per the ISTH definition. No articles used fatal bleeding as a component to define major bleeding. Approximately half of all articles used the component involvement of critical organ or site (n = 7). Requiring blood transfusion was used in 6 articles and only 4 used reduction in haemoglobin or haematocrit levels (none of these involved claims data). Conclusions This targeted literature review of retrospective database studies of routine clinical practice decodes proxy use of ISTH major bleeding definitions. Claims data were the most common data source but lacked components describing fatal bleeding and haemoglobin levels. Further research is vital to assess the variation in reported major bleeding rates in RWE studies using proxy definitions in place of the ISTH definition.Figure

#2090 Kidney Biopsy by Nephrologists in Patients with Severe Renal Impairment: Complications and histological Spectrum

Abstract Background and Aims Kidney biopsy is the gold standard test for assessing kidney disease and offers pivotal insights into the diagnosis, prognosis, and treatment of kidney disorders. However, its application in patients with a diminished glomerular filtration rate (GFR) poses a heightened risk of complications. In this study, we explored the safety and utility of kidney biopsy in patients with an estimated GFR <15 ml/min/1.73 m2. Method In this prospective study, we enrolled consecutive adult patients with an eGFR below 15 ml/min/1.73 m2 who underwent a kidney biopsy and provided informed consent. Exclusions comprised patients with solitary or transplanted kidneys or acute kidney injury. All biopsies were performed under ultrasound guidance. Following the procedure, patients were observed for 24 hours to monitor complications, and an analysis of their associated risk factors was done. Results Among the 88 patients included in the study, 60% were male, 20% had diabetes, and 30% were hypertensive. Chronic glomerulonephritis (45%), with IGA nephropathy being the most prevalent), chronic tubulointerstitial disease (43%), and diabetic kidney disease (12%) were the predominant histological diagnoses in kidney biopsies. Peri-renal hematomas ≥2 cm were observed in 9 patients, with three requiring blood transfusions. A major complication necessitating angioembolization occurred in one patient. The biopsy sample was deemed adequate in 80% of patients (n = 70). The requirement of blood transfusion (p < 0.04) and hemodialysis before biopsy (p = 0.05) was associated with an increased risk of complications. This study suggests the safety and necessity of kidney biopsy in CKD patients, underscoring its importance for accurate diagnosis and the initiation of appropriate therapeutic measures, irrespective of GFR Conclusion This study suggests the safety and necessity of kidney biopsy in CKD patients, underscoring its importance for accurate diagnosis and the initiation of appropriate therapeutic measures, irrespective of GFR

#2418 Effects of correction of acidosis on body composition and biochemical parameters in CKD patients on maintenance hemodialysis

Abstract Background and Aims Metabolic acidosis is a common problem in patients of chronic kidney disease and patients on maintenance hemodialysis. In resource poor countries, due to financial constraints frequency of dialysis and compliance to medication is adversely affected. This leads to worsening of clinical condition of patient and requirement of in hospital care, many times intensive care, further increasing cost of treatment. Metabolic acidosis has implications on bone and muscle health. Aim of our study was to assess the changes in body composition (fat percentage and lean body mass), changes in third space fluid, biochemical parameters, number of admissions and requirement of blood transfusions before and after correction of metabolic acidosis. Method This was a prospective, observational study. 25 patients on maintenance hemodialysis at our center were included in the study. Bio-impedance analysis (BIA), biochemical parameters (Complete blood counts, renal function tests, serum calcium and phosphorous, liver function tests, Blood gas analysis) were done at baseline before starting bicarbonate supplementation. Number of admissions and blood transfusions in 3 months prior to initiation of bicarbonate supplementation were noted. The oral bicarbonate supplementation was increased from baseline, based on the baseline blood gas analysis. The same parameters were assessed after 3 months and analyzed. Results At the end of 3 months we observed that there was significant reduction (p < 0.05) in total leucocyte counts (mean 8100/cumm to 6800/cumm), urea (mean 113.7 mg/dL to 83.72 ng/dL), creatinine (mean 7.87 mg/dL to 6.68 mg/dL), phosphorous (mean 5.18 mg/dL to 4.43 mg/dL), SGOT (mean 56.52 IU to 25.2 IU) and SGPT (mean 46.48 IU to 22.88 IU) with a trend of decrease (p ≤ 0.1) in percentage of extra cellular water (27.31% to 25.03%), lean body mass (44.27 kg to 43.0 kg) and trend of increase (p ≤ 0.1) in body fat composition (15.62 kg to 18.82 kg) and body fat percentage (26.924% to 31.90). There was a reduction in third space fluid (0.88 lit to 0.43 lit). The number of hospitalizations reduced (15 three months prior to initiation of therapy to 7 after initiation of therapy) and number of blood transfusions required also reduced (21 before initiation to 10 after initiation of therapy). Conclusion We concluded that correction of acidosis probably reduces the inflammation in patients of CKD on maintenance hemodialysis. This could be seen from the reduced total leucocyte counts, liver enzymes, urea and creatinine values. Changes in body composition with increased total fat mass, fat percentage and decreased lean mass was also noted. There was also a significant reduction in hospitalizations and number of blood transfusions.

#281 AVF formation is a common complication of percutaneous ultrasound-guided renal biopsy: a single-center analysis of risk factors and clinical outcome

Abstract Background and Aims Percutaneous renal biopsy is a key procedure for the work-up of renal diseases. Among the possible complications of such procedure, prevalence, risk factors and clinical outcome of arterio-venous fistula (AVF) formation is unclear. We present here a single-center experience on renal biopsy-related complications with a focus on risk factors for AVFs formation and their management. Method We retrospectively analyzed all the kidney biopsies performed in our center between January 2012 and December 2022. All biopsies were conducted under real-time ultrasound (US) guidance by trained nephrologists. Kidney US and doppler mapping were performed routinely 6 and 24 hours post-procedure. In accordance with the description provided in the US report, AVFs were categorized into small, moderate, and high-flow rates. Patients’ comorbidities, histologic sample characteristics, blood tests results and the clinical course were recorded. Logistic regression was employed to investigate potential risk factors for complications. Results 1016 adult native renal biopsies were performed. The average age of patients was 55 ± 17 years, and 677/1016 (66.6%) were males. The histological sample was unsuitable in 29/1016 (2.9%) of the cases; moreover, prevalence of renal medulla and presence of large-caliber arteriole were observed in 88/1016 (8.7%) and 38/1016 (3.7%) of the samples, respectively. The most common complication was hematoma, detected by US in 175/1016 (17.2%), which was considered “complicated” in 21/1016 (2.1%) due to the association with macroscopic hematuria (n = 10), blood transfusion requirement (n = 8), or signs of active bleeding (n = 8), requiring embolization in 6/1016 patients (0.6%). AVFs were identified in 119/1016 (11.7%) biopsies; of these 20/119 (16.8%) required embolization after a median time of 16 days (IQR 5-65). Spontaneous resolution was documented in 65/119 (55%) of cases and occurred after a median of 27 days (IQR 15-49), with 50/55 (90.9%) of cases spontaneously resolving within the first month and the remaining cases no later than the fourth month (Fig. 1). High-flow AVFs more frequently necessitated angiographic intervention compared to moderate and small AVFs (75% vs 25% vs 7%), with a prolonged spontaneous resolution time (median 78 days; IQR 51-106) (Table 1). In the cases requiring embolization, the median creatinine level before and 6 months after procedure was respectively 1.7 mg/dL and 1.9 mg/dL (paired Wilcoxon signed-rank test: p = 0.908). In three cases post-embolization, a loss of renal vascularization at angiography higher than 30% was reported; however, even in these cases no differences in terms of renal function were observed at 6 months compared to the baseline. At multivariate logistic regression, hypertension (OR = 2,2; p = 0.003; 95% CI [1.3-3.7]), renal medulla prevalence (OR = 2,8; p = 0,001; 95% CI [1.6-4.8]), and large-caliber arteriole presence (OR = 2,9; p = 0,008; 95% CI [1.3-6.3]) were associated with a higher risk of AVFs, while obesity emerged as a protective factor (OR = 0,27; p = 0,013; 95% CI [0.1-0.8]). Conclusion AVF is a common complication following renal biopsy but therapeutic intervention is rarely required, as spontaneous resolution is typically observed within one month. In case of symptomatic or persistent AVFs, embolization may be required without an apparent impact on the renal function, at least in the short term. Hypertension and surrogate factors associated with a deeper penetration of the needle into the renal parenchyma are associated with an increased risk of AVF. Conversely, obesity was protective toward the risk of AVF development.

Safety and feasibility of mini-open Wiltse approach in posterolateral lumbar stabilization and fusion: intra- and post-operative evaluation

BackgroundExpected operative challenges in minimally invasive spine surgeries as a result of restricted surgical field, unfamiliarity with surgical approaches and fear of complications are behind the preference of using traditional "open" spine surgery.ObjectivesTo evaluate the safety and feasibility of mini-open Wiltse approach in comparison with the conventional midline approach for posterolateral lumbar stabilization and fusion.Patients and methodsA retrospective comparative study conducted on 49 patients with low grade single level lumbar spondylolithesis who were surgically treated in our Department between May 2020 and May 2022. Patients who were surgically treated with traditional midline approach were included in group (A) and patients in whom the mini-open Wiltse approach was used, were assigned to group (B). The two groups were compared regarding various intra and postoperative parameters.ResultsGroup (A) included 27 patients (55.1%) operated upon with the classic midline approach and 22 patients (44.9%) were surgically treated using the Wiltse approach (group B). The mean patients' age (50.43 ± 5.538) years and L4-5 was the most commonly affected level (71.4%). The intra-operative parameters (operation time, blood loss and fluoroscopy time) showed significant lower results (P < 0.001) among patients of group (B). No cases in the group (B) required blood transfusion versus 5 cases in group (A) (P = 0.033). Postoperatively, the Oswestry Disability Index (ODI) and Visual analogue scale (VAS) scores were significantly improved in each group in comparison to the preoperative scores (P < 0.001). However, after 3 months the ODI score in group (B) was superior to that in group (A) (P = 0.045) and postoperative VAS score in group (B) was significantly improved compared to that in group (A) at discharge (P = 0.016), and also after 1 and 3 months (P < 0.001). Patients operated with Wiltse approach had a shorter duration of hospital stay but the difference was not statistically significant (P = 0.090).ConclusionsBecause of minimal trauma to the muscles and soft tissues, the mini-open Wiltse approach can be faster, safer and requires less recovery time as opposed to the classic midline approach.

Short-term outcomes of robotic tumor-specific mesorectal resection of rectal cancer: surgical techniques in mesorectal division using rolling division of the mesorectum.

This study aims to report our surgical techniques for robot-assisted laparoscopic anterior resection, specifically focusing on mesorectal division using rolling division of the mesorectum, and to elucidate short-term outcomes at a single institution. Tumor-specific mesorectal excision (TSME) is commonly performed for resection of a tumor located in the upper rectum. However, especially in a narrow pelvis, it is difficult to perform appropriate mesorectal division at an adequate distance from the tumor in robot-assisted laparoscopic anterior resection. Retrospective case series of patients with rectal cancer who underwent robot-assisted TSME using rolling division of mesorectum. Patient characteristics, perioperative clinical results, surgical and pathological details were recorded. A total of 198 patients underwent robot-assisted TSME for rectal cancer using rolling division of mesorectum between May 2019 and December 2023.The tumor was located in the upper rectum in 45 patients, middle rectum in 115 patients and lower rectum in 38 patients. The types of resections were 40 high anterior resection and 158 low anterior resections. The median operation time was 175 (range 109-310) min, and median mesorectal division time was 24 (range 15-45) min. Median blood loss was 3 (range 0-20) ml; no patients required blood transfusion. The overall complication rate of Clavien-Dindo classification grades I-IV was 7.1%. Anastomotic leakage was observed in two patients (1.0%) with grade III. There was no surgical mortality in this series. This robotic technique for anterior resection is a feasible and reliable procedure for achieving sufficient and safe TSME in this cohort.

Early Experience with EndoRobotic Submucosal Dissection (ERSD): Pathologic and Short-term Outcomes in the First 28 Patients.

To evaluate the safety and feasibility of single-port endorobotic submucosal dissection (ERSD) using the Da Vinci SP platform for the management of rectal neoplasms. Endoscopic submucosal dissection (ESD) offers a potential organ-sparing treatment for advanced colorectal neoplasms but demands high technical skill and a steep learning curve. Advances in semiflexible robotic platforms, such as the Da Vinci SP, promise to simplify this procedure, potentially offering improved outcomes for patients with benign rectal neoplasms. A retrospective analysis of 28 patients who underwent ERSD using the Da Vinci SP platform between 2020 and 2023 was performed. Patient demographics, lesion characteristics, procedure details, outcomes, and complications were reviewed. The primary endpoint was successful en-bloc resection. The cohort had a median age of 60.5 years and a median BMI of 28.2kg/m², predominantly male(67.8%) with ASA categories 2 or 3(82%). Lesions had a median size of 38mm and were located a median of 9cm from the anal verge. The median procedure time was 87.5 minutes. En-bloc resection was achieved in all cases(100%), with no intraoperative complications or mortality. One patient experienced urinary retention, and one had late bleeding requiring blood transfusion. Pathology outcomes included 46.4% tubulovillous adenomas, 21.4% adenocarcinomas, and high-grade dysplasia in 53.6% of patients. Single-port ERSD using the Da Vinci SP platform is safe and feasible for the management of colorectal neoplasia, ensuring a high rate of en-bloc resection. It potentially offers advantages over conventional ESD, including shorter dissection times, although further studies are necessary for a definitive comparison.

Impact of anemia on incidence of perioperative lower limb deep vein thrombosis in patients undergoing total hip arthroplasty

To explore the impact of anemia on the incidence of perioperative lower limb deep vein thrombosis (DVT) in patients undergoing total hip arthroplasty (THA). A retrospective analysis was conducted on clinical data of 1 916 non-fracture patients who underwent THA between September 2015 and December 2021, meeting the selection criteria. Among them, there were 811 male and 1 105 female patients, aged between 18 and 94 years with an average of 59.2 years. Among the patients, 213 were diagnosed with anemia, while 1 703 were not. Preoperative DVT was observed in 55 patients, while 1 861 patients did not have DVT preoperatively (of which 75 patients developed new-onset DVT postoperatively). Univariate analysis was performed on variables including age, gender, body mass index (BMI), diabetes, hypertension, history of tumors, history of thrombosis, history of smoking, revision surgery, preoperative D-dimer positivity (≥0.5 mg/L), presence of anemia, operation time, intraoperative blood loss, transfusion requirement, and pre- and post-operative levels of red blood cells, hemoglobin, hematocrit, and platelets. Furthermore, logistic regression was utilized for multivariate analysis to identify risk factors associated with DVT formation. Univariate analysis showed that age, gender, hypertension, revision surgery, preoperative levels of red blood cells, preoperative hemoglobin, preoperative D-dimer positivity, and anemia were influencing factors for preoperative DVT ( P<0.05). Further logistic regression analysis indicated that age (>60 years old), female, preoperative D-dimer positivity, and anemia were risk factors for preoperative DVT ( P<0.05). Univariate analysis also revealed that age, female, revision surgery, preoperative D-dimer positivity, anemia, transfusion requirement, postoperative level of red blood cells, and postoperative hemoglobin level were influencing factors for postoperative new-onset DVT ( P<0.05). Further logistic regression analysis indicated that age (>60 years old), female, and revision surgery were risk factors for postoperative new-onset DVT ( P<0.05). The incidence of anemia is higher among patients with preoperative DVT for THA, and anemia is an independent risk factor for preoperative DVT occurrence in THA. While anemia may not be an independent risk factor for THA postoperative new-onset DVT, the incidence of anemia is higher among patients with postoperative new-onset DVT.

Complications of placenta previa: A retrospective observational study at tertiary care hospital

: Placenta previa (PP) is condition where the placenta is inserted completely or partially into the lower uterine segment, at or after 28 weeks of gestation. Maternal and fetal risks are antepartum haemorrhage (APH), postpartum haemorrhage (PPH), abnormal adherence of placenta, low birth weight (LBW), intra uterine growth restriction (IUGR), preterm births and congenital malformations. The purpose of this study was to determine the proportion of placenta previa, the demographics of patients, types- severity, complications and the feto-maternal outcome in patients of placenta previa.: After due permission of Institutional Review Board, this retrospective observational study was carried out at tertiary care teaching hospital from July 2020 to November 2022.Proportion of pregnancies with placenta previa was 0.3%. Majority 44(91.7%) patients were registered, 38(79.2%) of patients were in age group of 21-30 years, 38(79.1%) patients were multigravida, 41 (85.4%) had major degree of placenta previa, 29(60.4%) patients admitted after 37 weeks of gestation and 47(97.9%) of patients were delivered by caesarean section. Majority of patients, 20 (41.7%) had mild anemia. Major complications were bleeding episodes during antenatal period/APH in 23 (47.9%) and PPH in 22 (45.8%) patients. Maternal mortality occurred in 1 (2.1%) patient. All babies were live at time of birth and 44(91.7%) babies were alive at the time of discharge and neonatal death occurred in 4 (8.3%) preterm babies (28-33 week gestation). Majority of patients were multigravida. No patient was severely anaemic. Majority of patients were delivered by CS. APH and PPH were major complications. About two third of patients required blood transfusion in ante/intra/post-natal period. Obstetric hysterectomy was required in about one tenth of patients. Majority of babies were alive at the time of discharge due to higher number of registered patients who took regular antenatal care, hospital delivery and good NICU facilities. Once diagnosed, placenta previa and morbidly adherent placenta should be managed at tertiary care centre with multidisciplinary approach so as to lessen the feto-maternal morbidity and mortality. Prevention is better than cure. Multiparity increases the risk of placenta previa. Hence, family planning with an aim to reduce unwanted pregnancies and abortions will help to reduce the chances placenta previa. CS increases the risk of development of placenta previa. Efforts should be made to reduce the primary caesarean section rate as it poses more risk of placenta previa, morbidly adherent placenta and its related complications in subsequent gestations.

Predicting blood transfusion following traumatic injury using machine learning models: A systematic review and narrative synthesis.

Haemorrhage is a leading cause of preventable death in trauma. Accurately predicting a patient's blood transfusion requirement is essential but can be difficult. Machine learning (ML) is a field of artificial intelligence that is emerging within medicine for accurate prediction modelling. This systematic review aimed to identify and evaluate all ML models that predict blood transfusion in trauma. This systematic review was registered on The International Prospective register of Systematic Reviews (CRD4202237110). MEDLINE, Embase and the Cochrane Central Register of Controlled Trials were systematically searched. Publications reporting a ML model that predicted blood transfusion in injured adult patients were included. Data extraction and risk of bias assessment was performed using validated frameworks. Data was synthesised narratively due to significant heterogeneity. Twenty-five ML models for blood transfusion prediction in trauma were identified. Models incorporated diverse predictors and varied ML methodologies. Predictive performance was variable but eight models achieved excellent discrimination (AUROC >0.9) and nine models achieved good discrimination (AUROC >0.8) in internal validation. Only two models reported measures of calibration. Four models have been externally validated in prospective cohorts: the Bleeding Risk Index, Compensatory Reserve Index, the Marsden model and the Mina model. All studies were considered at high risk of bias often due to retrospective datasets, small sample size and lack of external validation. This review identified twenty-five ML models developed to predict blood transfusion requirement after injury. Seventeen ML models demonstrated good to excellent performance in-silico but only four models were externally validated. To date ML models demonstrate the potential for early and individualised blood transfusion prediction but further research is critically required to narrow the gap between ML model development and clinical application. Systematic Review Without Meta-Analysis, Level IV.

Pre-Operative Group and Save in Elective and Emergency Laparoscopic Cholecystectomy: Necessity, Cost-Effectiveness, and Own Experience.

Background: Laparoscopic cholecystectomy is associated with a high safety profile. This study seeks to quantify the incidence of blood transfusion in both the elective and emergency settings, examine related patient outcomes, and investigate selection criteria for pre-operative Group and Save (G&S) sampling. Methods: A prospective multi-centre observational study was conducted to investigate patients undergoing either elective or emergency laparoscopic cholecystectomy in the UK between January 2020 and May 2021. Multivariate logistical regression models were used to identify patient factors associated with the risk of transfusion and explore outcomes linked to pre-operative G&S sampling. Results: This study comprised 959 patients, with 631 (65.8%) undergoing elective cholecystectomy and 328 (34.2%) undergoing emergency surgery. The median age was 48 years (range: 35-59), with 724 (75.5%) of the patients being female. Only five patients (0.5%) required blood transfusions, receiving an average of three units, with the first unit administered approximately six hours post-operatively. Among these cases, three patients (60%) had underlying haematological conditions. In adjusted models, male gender was significantly associated with the need for a blood transfusion (OR 11.31, p = 0.013), while the presence of a pre-operative Group and Save sample did not demonstrate any positive impact on patient outcomes. Conclusions: The incidence of blood transfusion following laparoscopic cholecystectomy is very low. Male gender and haematological conditions may present as independent risk factors. Pre-operative G&S sampling did not yield any positive impact on patient outcomes and could be safely excluded in both elective and emergency cases, although certain population subsets will warrant further consideration.

Management of renal sinus angiomyolipoma: modified robotic nephron-sparing surgery in a single center

BackgroundRenal sinus angiomyolipoma (RSAML) is a rare and typically complex renal tumor. The objective is to present our single-center experience with a modified technique of robotic nephron-sparing surgery (NSS) for treating RSAML.MethodsWe retrospectively evaluated 15 patients with RSAMLs who were treated with robotic NSS at the Department of Urology of Tongji hospital, ranging from November 2018 to September 2022. Renal vessels and ureter were dissected. The outer part of RSAML was resected. The rest of tumor was removed by bluntly grasp, curettage and suction. Absorbable gelatin sponges were filled in the renal sinus. The preoperative parameters, operative measures and postoperative outcomes were all collected. Follow-up was performed by ultrasonography and estimated glomerular filtration rate (eGFR).ResultsRobotic NSS was successfully performed in all the patients, without any conversion to open surgery or nephrectomy. The mean operation time was 134.13 ± 40.56 min. The mean warm ischemia time was 25.73 ± 3.28 min. The median estimated blood loss was 100 [50, 270] ml and 1 patient required blood transfusion. The mean drainage duration was 5.77 ± 1.98 days. The median postoperative hospital stay was 6.90 [5.80, 8.70] days. Two patients experienced postoperative urinary tract infection (Clavien-Dindo Grade II). During the median follow-up of 25.53 ± 15.28 months, patients received 91.18% renal function preservation. No local recurrence occurred in all the patients.ConclusionsRobotic NSS for RSAML is a complicated procedure that demands technical expertise and a well-designed strategy is critical in the operation. Treating RSAML with modified robotic NSS is safe, effective and feasible.

Comparative evaluation of postoperative outcomes and expenditure between robotic and conventional single-level lumbar fusion surgery: a comprehensive analysis of nationwide inpatient sample data.

In this study, we investigate the evolution of lumbar fusion surgery with robotic assistance, specifically focusing on the impact of robotic technology on pedicle screw placement and fixation. Utilizing data from the Nationwide Inpatient Sample (NIS) covering 2016 to 2019, we conduct a comprehensive analysis of postoperative outcomes and costs for single-level lumbar fusion surgery. Traditionally, freehand techniques for pedicle screw placement posed risks, leading to the development of robotic-assisted techniques with advantages such as reduced misplacement, increased precision, smaller incisions, and decreased surgeon fatigue. However, conflicting study results regarding the efficacy of robotic assistance in comparison to conventional techniques have prompted the need for a thorough evaluation. With a dataset of 461,965 patients, our aim is to provide insights into the impact of robotic assistance on patient care and healthcare resource utilization. Our primary goal is to contribute to the ongoing discourse on the efficacy of robotic technology in lumbar fusion procedures, offering meaningful insights for optimizing patient-centered care and healthcare resource allocation. This study employed data from the Nationwide Inpatient Sample (NIS) spanning the years 2016 to 2019 from USA, 461,965 patients underwent one-level lumbar fusion surgery, with 5770 of them having the surgery with the assistance of robotic technology. The study focused primarily on one-level lumbar fusion surgery and excluded non-elective cases and those with prior surgeries. The analysis encompassed the identification of comorbidities, surgical etiologies, and complications using specific ICD-10 codes. Throughout the study, a constant comparison was made between robotic and non-robotic lumbar fusion procedures. Various statistical methods were applied, with a p value threshold of < 0.05, to determine statistical significance. Robotic-assisted lumbar fusion surgeries demonstrated a significant increase from 2016 to 2019, comprising 1.25% of cases. Both groups exhibited similar patient demographics, with minor differences in payment methods, favoring Medicare in non-robotic surgery and more private payer usage in robotic surgery. A comparison of comorbid conditions revealed differences in the prevalence of hypertension, dyslipidemia, and sleep apnea diagnoses-In terms of hospitalization outcomes and costs, there was a slight shorter hospital stay of 3.06days, compared to 3.13days in non-robotic surgery, showcasing a statistically significant difference (p = 0.042). Robotic surgery has higher charges, with a mean charge of $154,673, whereas non-robotic surgery had a mean charge of $125,467 (p < 0.0001). Robotic surgery demonstrated lower rates of heart failure, acute coronary artery disease, pulmonary edema, venous thromboembolism, and traumatic spinal injury compared to non-robotic surgery, with statistically significant differences (p < 0.05). Conversely, robotic surgery demonstrated increased post-surgery anemia and blood transfusion requirements compared to non-robotic patients (p < 0.0001). Renal disease prevalence was similar before surgery, but acute kidney injury was slightly higher in the robotic group post-surgery (p = 0.038). This is the first big data study on this matter, our study showed that Robotic-assisted lumbar fusion surgery has fewer post-operative complications such as heart failure, acute coronary artery disease, pulmonary edema, venous thromboembolism, and traumatic spinal injury in comparison to conventional methods. Conversely, robotic surgery demonstrated increased post-surgery anemia, blood transfusion and acute kidney injury. Robotic surgery has higher charges compared to non-robotic surgery.

Morbidity pattern and impact of hydroxyurea therapy among sickle cell patients in Raipur district of Chhattisgarh

ABSTRACT Background: Sickle cell disease (SCD) is a disorder marked by a single-point mutation in the beta-globin gene. Hydroxyurea is a globally accepted disease-modifying agent that sounds to be effective in managing clinically and probably preventing complications of SCD. The current study aims to document the morbidity pattern and impact of Hydroxyurea therapy in the Outpatient Department of Sickle Cell Institute, Raipur. Materials and Methods: This cross-sectional study was conducted among randomly selected sixty-five patients (adults and children above six years). After obtaining informed consent, relevant data were collected in a predesigned pretested questionnaire. The appropriate statistical exercise was applied for the interpretation of results and inferences. Results: Acute febrile illness 54 (83%) and 53 (81.5%) reported pain crisis observed to have the most common morbidity among the study subjects, followed by 55.4% (36), 33 (50.8%) jaundice and difficulty breathing, respectively. Joint pain was the most commonly observed complaint, particularly at the knee joint (76.9%). Other complaints such as hand-foot syndrome (24.6%), epistaxis (27.7%), and acute chest syndrome (21.5%). Vaso-occlusive crisis (72.4%), difficulty in walking (60.0%) and eyesight (35.4%), leg ulcers (9.2%), and dactylitis (3.1%) were also documented as clinical manifestations among study participants. Less than half (44.46%) had an awareness about SCD. Hydroxyurea therapy was highly significant in improving the patient’s clinical picture (P &lt; 0.01), especially following the frequency of hospitalization and the requirement for blood transfusion. Conclusion: Pain crisis is the most common morbidity among study participants with a low level of knowledge about SCD with febrile illness. Hydroxyurea therapy was found to be quite effective as a disease-modifying therapy, especially for reducing the frequency of blood transfusion and lowering hospitalization rates among SCD patients.

Memorial Regional Hospital Placenta Accreta Spectrum Program: Quality Evaluation of Outcomes [ID 2683637

INTRODUCTION: Placenta accreta spectrum (PAS) affects 1/272 deliveries with a mortality rate of 7%, which is often related to life-threatening hemorrhage. Morbidity related to PAS is often due to complications such as hemorrhage requiring blood transfusion, intensive care unit (ICU) admission, and prolonged hospital stay. The American College of Obstetricians and Gynecologists supports a multidisciplinary approach to management of pregnancies complicated by PAS, and as such our protocol for management of PAS was started in 2016. Our approach to the management of PAS includes a high-risk navigation team, monthly multidisciplinary team meetings, early admission for surgical planning, a dedicated team with 24-hour coverage, blood bank specialist involvement at the time of surgery, the availability of backup surgeons, and coordination with other surgical subspecialties. METHODS: This project is a quality review of outcomes of 216 females between 2016 and 2023. Using linear regression analysis, we evaluated four primary outcomes: quantitative blood loss (QBL), blood products transfusion (BPT), length of stay (LOS), and ICU admissions. RESULTS: Linear regression outcomes showed that our QBL, BPT, and LOS among non-ICU patients is lower than the national average and within national average among those admitted to the ICU, with the exception of BPT. Finally, placenta pathology and location may not be a major factor negatively affecting surgical outcomes among PAS patients in a structured program and should be a factor considered when developing PAS centers. CONCLUSION: Our findings from our quality review support the use of a multidisciplinary and surgically structured approach for managing patients with PAS.

Seven-year review of emergency peripartum hysterectomy in a tertiary hospital in northern Nigeria

Background: Emergency peripartum hysterectomy (EPH) is surgical removal of the uterus during childbirth or within its immediate 24 hours, a lifesaving procedure done as the last resort to control obstetric haemorrhage. Objectives: To determine the incidence, indications, and complications of peripartum hysterectomy. Methods: The study is a retrospective review of emergency peripartum hysterectomies performed at the Centre from 1st January, 2015 to 31st December, 2021. The patients’ case folders were retrieved from the medical records department and relevant information obtained using a structured data extraction format. The data was analyzed using SPSS version 26. Means, frequency, and percentages were used to present the significance of the results. Results: A total of 46 EPH were performed between January 2015 and December 2021 out of 20,832 deliveries within the same period, giving an incidence of 0.22% (2.2 per thousand deliveries). Indications were uterine rupture (78.2%), uterine atony (10.9%), abruptio placentae (4.3%), placenta previa (4.3%) and placenta accreta spectrum (2.2%). Subtotal hysterectomy was performed in most cases (39/46; 84.8%). The most common complication was intraoperative haemorrhage requiring blood transfusion (100%). Other complications included severe post-operative anaemia, wound sepsis, paralytic ileus and enterocutaneous fistula. The maternal case fatality was 4 (8.7%) and all the mortality cases were unbooked patients. Conclusion: The incidence of emergency peripartum hysterectomy is relatively low in our study and uterine rupture is the most common indication. EPH is associated with significant maternal morbidity and mortality, and this is related to booking status. Hence, enlightening women on antenatal care and hospital delivery will help in reducing maternal morbidity and mortality.

Multiple Immune Dysregulation Conditions with a Single Underlying Root Cause of NRAS Gene-Positivity: A Case Report

Hematological malignancies in particular are recognized to be linked to immunological dysregulated disorders such hematolytic anemia, immunodeficiency, and autoimmune illnesses. We describe a rare case that had multiple immune dysregulation symptoms and was subsequently found to be positive for the NRAS gene. A male, 29, complained of pleuritic chest pain. On the ECG, he showed broad PR depression and elevated PR in aVR, along with elevated troponin. He received colchicine and NSAIDs as treatment with a good response and resolution of his symptoms. After four weeks, he developed a fever which thought to be secondary to perianal abscess, and a surgical incision and drainage along with broad spectrum antibiotics was used to treat a perianal abscess. Despite receiving extensive medical and surgical care, his fever persisted. His blood film started to show circulating blast cells. Following an immediate bone marrow aspiration and biopsy, there were no notable abnormalities seen, and a 1% blast was present, which was assumed to be the result of stress or infection. Later, a weak positive +1 Coombs (DAT) test is developed and caused active hemolytic anemia required blood transfusion. Along with the anemia, a wrist expanding wound was discovered in the previous IV cannula site. Clinically wound appears as a pyoderma gangrenosum. Histopathology showed purulent dermal inflammation including many neutrophils and macrophages. This feature of micro abscess formation was consisting with the diagnosis of pyoderma gangrenosum. An intravenous steroid (1 mg/kg) was administered in response to a positive Coombs test and pyoderma gangrenosum. The patient's condition greatly improved overall. His wound began to heal as his white blood cell count dropped. After being given oral steroids with a titration-down plan, the patient was sent home. A whole genome sequence was performed on him because he had peri myocarditis, pyoderma gangrenosum, and hematolytic anemia. The results show that he is NRAS gene positive. He was attentively observed clinically with regular out-patient follow-ups as this gene is strongly associated with hematological cancers. He developed symptomatic normocytic anemia a few months later, and a bone marrow aspiration and biopsy were performed to confirm the presence of Myelodysplastic syndromes (MDS). He was transferred to another facility and underwent chemotherapy and bone marrow transplant. In otherwise healthy individuals, the idea of offering a single explanation—Occam's razor—must be considered and investigated. Finding the underlying reason could improve patient care, enable precision therapy, and alter the course of events.

Impact of blood salvage therapy during oncologic liver surgeries on allogenic transfusion events, survival, and recurrence, an ambidirectional cohort study.

The use of autologous blood transfusions in oncologic surgeries is somewhat controversial due to the potential risk of disease dissemination through the salvage process. On the other hand, autologous blood transfusion can prevent the potential negative effects of allogenic blood transfusions and reduce use of valuable resources. This study included 106 adult patients who underwent oncologic liver surgery at our institution between December 2015 and June 2019. The patients were divided into two groups: the Cell Saver® group (operated between January 2018 and June 2019) and the control group (operated between December 2015 and December 2017). The Cell Saver® device was present in the operating room for the Cell Saver® group, and blood was re-transfused if a certain amount of blood loss occurred. Data analysis focused on outcomes such as blood transfusion requirements, overall survival, recurrence-free survival, hemoglobin levels, hospital stay, and complications. Patient records provided relevant information on demographics, surgery details, pathology, and outcomes for both groups. Autologous blood transfusion was found to reduce the amount of blood units needed (4.0 units (control group) versus 0.4 units (Cell Saver® group) P=0.029. Kaplan-Meier curves showed no difference for both overall survival 471.6 days (Cell Saver® group) versus 468.3 days (control group) (P=0.219) and 488.9 days (Cell Saver® group) versus 487.2 days (control group) (P=0.993) and disease-free survival (P=0.553) and (P=0.735) for primary hepatic tumours and hepatic metastasis respectively between the Cell Saver® and control groups. Overall survival regardless of the type of tumour was similar to the control group (485.4d vs. 481.9d) (P=0.503). Survival was significantly lower for minor hepatectomies (516.0d vs. 517.4d) (P=0.050) in the Cell Saver® group, major hepatectomies showed no difference in overall survival (470.2d vs. 466.4d) (P=0.868). No impact on disease recurrence was found between patients who received autologous blood transfusions versus those who did not. The use of Cell Saver® should not be avoided in oncologic surgeries of the liver. Use of Cell Saver® for major hepatectomies might be more beneficial as OS was significantly lower for the Cell Saver® group for patients who underwent minor hepactomies. Further research is needed to explain this conflicting result. Nonetheless, the use of Cell Saver® in autologous blood transfusions can reduce the use of valuable resources and the risks associated with allogenic blood transfusions.

Necrotising enterocolitis in a middle-income country: Early onset and risk factors for mortality.

There is limited literature available about necrotising enterocolitis (NEC) in low- and middle-income countries. This study sought to determine the proportion, pattern and risk factors for mortality among very low birth weight (VLBW) neonates with NEC in a middle-income setting. A retrospective observational cohort study was conducted on all infants with birth weights less than 1501 g admitted from 2018 to 2020 at Groote Schuur Hospital, Cape Town, South Africa. Data were obtained from the Vermont Oxford Network and hospital folders. A total of 104/1582 (6.6%) neonates were diagnosed with NEC with a median onset of 8 days of life. The mortality rate was 39.0%, compared to the all-cause mortality rate of 18.7% for VLBW neonates. Thirty-two (32.0%) neonates with NEC were transferred for surgery of whom 10 (31.3%) died. Small for gestational age (p = 0.13), NEC stage 2B or above (p = 0,002), a positive blood culture (p = 0.018), a raised C-reactive protein (p = 0.013), hyponatraemia (p = 0.004), anaemia requiring blood transfusion (p = 0.003) and thrombocytopenia requiring platelet transfusion (p = 0.033) were associated with mortality. A positive blood culture was found in 37.0% with a predominance of Klebsiella pneumoniae isolates. NEC has an early onset and a high mortality rate in our setting.
