Postoperative atrial fibrillation following noncardiac surgery is associated with long-term heart failure: insights from a nationwide cohort

Abstract Background Atrial fibrillation (AF) is associated with the development of heart failure (HF). Whether postoperative AF (POAF) also confers a greater risk of HF is unclear. Purpose To investigate the long-term rate of incident HF in patients developing new-onset POAF after noncardiac surgery relative to patients who did not develop POAF after noncardiac surgery. Methods In this cohort study, the Danish nationwide registries were used to identify all patients aged ≥30 years who developed POAF following noncardiac, nonobstetric surgery from 1996 to 2020. These patients were matched in a 1:3 ratio by age, sex, type of surgery, selected comorbidities, and year of inclusion with patients without POAF after noncardiac surgery. The primary outcome was incident HF. Secondary outcomes were HF hospitalization and all-cause mortality. Results A total of 2,270 patients with POAF were matched with 6,810 patients without POAF (median age: 75 years [25th-75th percentile: 67-82 years]; 53.5% females). The median follow-up was 7.2 years. Compared with patients without POAF, those with POAF had a higher associated long-term rate of incident HF (2.6 versus 1.2 events per 100 person-years; HR 2.39 [95% CI 2.06-2.78]]), HF hospitalization (2.2 versus 1.0 events per 100 person-years; HR 2.33 [95% CI 1.97-2.74]), and all-cause mortality (9.8 versus 7.4 events per 100-person-years; HR 1.55 [95% CI 1.45-1.66]) (Figure 1). Conclusions Patients with new-onset postoperative atrial fibrillation following noncardiac surgery had a higher associated long-term rate of incident heart failure compared to those without postoperative atrial fibrillation following noncardiac surgery. These findings highlight the importance of increased awareness among physicians of the risk of adverse outcomes, including heart failure, in patients with postoperative atrial fibrillation after noncardiac surgery. Closer postoperative follow-up and monitoring, as well as aggressive treatment of cardiovascular risk factors, may be warranted to reduce the risk of adverse outcomes in these patients.

Factors influencing hospital stay duration in an elective cardiac surgery cohort

Abstract Cardiac surgery has become more complex in recent years, with increases in patient age, complexity, and associated costs. The use of a multidisciplinary strategy to analyze and standardize patient management offers significant benefits. The development of Enhanced Recovery After Surgery (ERAS) programs has proven useful in various types of surgery, recently including cardiac surgery, yielding good results. One of the primary objectives of ERAS programs is the reduction of the Inpatients' length of stay (LOS), with the subsequent improvement in the patient experience and a reduction in costs. The aim of this study is to analyze preoperative and postoperative factors related to the LOS reduction in a cohort of elective cardiac surgery patients included in the Cardiac ERAS program at our hospital. All patients included in the ERAS program, corresponding to elective cardiac surgery, were included in the analysis. 138 patients were divided into four quartiles based on the inpatient’s LOS. An extensive search was conducted in our quality control database, which contains 470 variables on the factors more strongly associated with LOS. The results were analyzed using Chi-Square test for categorical and the Kruskal-Wallis test for continuous variables, generally of non-normal distribution. The results are summarized in the table. Age, poor mobility, surgery other than coronary bypass, and reoperation were the non-modifiable factors most associated with a prolonged LOS. Lower preoperative hemoglobin and albumin levels were associated with an increase in LOS. A class 3 or 4 NYHA functional class, chronic pulmonary disease, and anticoagulation use were associated with higher LOS. Classic cardiovascular risk factors, such as dyslipidemia, hypertension, and tobacco use, were not associated with differences in hospitalization duration. Postoperative and intraoperative factors associated with higher LOS included extubation in the operating room or within six hours, ICU stay duration, mobilization on postoperative days one and two, time to oral food tolerance and gut motility recovery, hyperglycemia on postoperative day one, the duration of arterial, venous, and urinary catheters, the amount of fluids on postoperative day one and the opioid use in POD 2. The complications most associated with a prolonged duration were any infectious complication, any respiratory complication, reoperation, readmission to intensive care, transfusion after 12 hours or at any time during hospitalization, prolonged postoperative sedation, and any rhythmic complication. Conclusion In our cohort of elective patients for cardiac surgery, factors traditionally addressed by ERAS programs were identified as being associated with a longer inpatient’s length of stay. Pre-operative nutritional and anemia optimization, early extubation and mobilization, and the prevention of respiratory and infectious complications should be targeted to improve hospital stay duration.

Evaluation of the Effect of Surgical Drapes on Intraoperative Hypothermia: A Randomized Clinical Trial.

Many patients experience unintended hypothermia in intraoperative processes. This randomized clinical trial aims to investigate the impact of surgical drapes on hypothermia during the intraoperative period. A randomized clinical trial was conducted from April 2019 to November 2020 in the Department of Anesthesiology and Reanimation/Operating Rooms at an education and research hospital. Out of 205 patients assessed for eligibility, 74 underwent elective abdominal surgery and were randomized into two groups: nonwoven surgical drapes and woven surgical drapes. The study had two stages: preoperative and intraoperative. Preoperative data were collected using information and evaluation forms, while intraoperative assessment involved forms for wetness and weight. Tympanic and esophageal temperatures were recorded every 15 minutes, and surgical drapes were weighed with a precision scale before and after surgery. There was no significant difference between the two groups in terms of body mass index, irrigation amount, surgery duration, gender, and preoperative shivering (p > 0.05). A statistically significant difference was found in preoperative body temperature (36°C), type of surgery, and intraoperative hypothermia (p < 0.05). Both types of surgical drapes were wet, but this difference was not statistically significant between the nonwoven group (mean ± SD [1368 ± 607]) and the woven group (mean ± SD [1335 ± 636], p = 0.824). This study demonstrated that neither woven nor nonwoven surgical drapes, nor the wetness of the surgical drapes, had a significant effect on intraoperative hypothermia. However, there is a need for randomized controlled trials involving uniform types of surgery related to the topic.

Pattern of Surgical Antibiotic Prophylaxis in a Tertiary Care Hospital of Bangladesh

Background: Surgical Site Infection (SSI) is a common form of hospital-acquired infection and major cause of postoperative illness accounting for approximately a quarter of all nosocomial infections. As a result, surgical antibiotic prophylaxis is now considered essential to conventional surgical procedure in order to reduce surgical site infections and improve postoperative recovery. The misuse and overuse of antibiotics has led to an increase in treatment costs and the emergence of antimicrobial resistance. The goal of the study is to identify the pattern of prophylactic antibiotic prescriptions for different surgical operations. Materials and methods: A retrospective observational study was conducted among 600 patients undergoing different surgeries in a tertiary care hospital of private setting in Dhaka, Bangladesh from July 2023 to December 2023. The demographic data, types of surgery, types of therapy, choice of antibiotic along with dosage formulations were collected. Results: Out of 600 patients, 245 (41%) were male and 355 (59%) were female. Highest bulk of patients were from Department of General Surgery (47.5%), followed by Department of Obstetrics &amp; Gynecology (24.16%) and Department of Otolaryngology (16.7%). Surgical prophylactic antibiotic was used in all 600 patients, and all antibiotics were given in intravenous route (100%). Almost 505 patients (84.2%) had received ceftriaxone as antimicrobial agent. Ceftriaxone with metronidazole or gentamicin and Cefuroxime with metronidazole or amikacin drugs combination were given to 75 (12.5%) and Cefuroxime, Amikacin, Metronidazole drugs combination were given to 20 patients (3.3%). 3rd generation cephalosporin, Ceftriaxone, was the most commonly prescribed antibiotic as monotherapy (94.3%), followed by 2nd generation cephalosporin, cefuroxime (4%). Conclusion: Ceftriaxone was the preferred antibiotic for surgical prophylaxis. Existence of an antimicrobial guideline along with antibiotic stewardship program in every hospital could be helpful for prescribers to play role in containment of antimicrobial resistance.

Postoperative heart valve infection, when and which bacteria: a nationwide cohort study

Abstract Background In patients undergoing heart valve surgery, subsequent bacteremia and infective endocarditis are feared events due to the associated high mortality. Knowledge on the incidence and specification of bacteremia following left-sided valve surgery are sparse and may have implications for prophylactic strategies and follow-up. Purpose To examine the six months incidence of bacteremia and infective endocarditis following left-sided heart valve surgery. Methods In the period from January 2010 to December 2021 all patients undergoing left-sided valve surgery were identified using Danish nationwide registries. Patients were followed until a maximum of six months, end of study, emigration, death, or outcome of interest (i.e., bacteremia or infective endocarditis). Cumulative incidence curves were computed with death as a competing risk stratified on bacterial species and for subgroups of interest: type of valve surgery, age, and sex. Results A total of 14,305 patients were included in the study. The majority of the study population were male (68.6%), and the median age was 70.2 years (25th-75th percentile 62.0-76.0 years). In total, 10,469 (73.2%) of the study population underwent aortic valve surgery, 3,497 (24.5%) underwent mitral valve surgery, while 339 (2.4%) underwent surgery on both valves. The cumulative incidence of bacteremia at six months of follow-up was 2.4% (95% CI 2.2-2.7%), Figure 1. For the overall study population, the most frequently occurring bacteremia was with Coagulase-negative Staphylococci (28%) and Staphylococcus aureus (14%). Within 30 days 0.35% of the patients had bacteremia with coagulase-negative staphylococci while this was 0.68% at six months of follow-up. For Staphylococcus aureus this was 0.19% and 0.34%, respectively. The cumulative incidence of infective endocarditis at six months of follow up was 1.0% (95% CI 0.8-1.2%). The majority of the infective endocarditis incidents were blood culture negative (27%) or caused by Enterococci (19%), Streptococci (17%) or Coagulase-negative Staphylococci (17%) while Staphylococcus aureus accounted for 14%. In crude analysis, simultaneous surgery on the mitral and aortic valve was associated with a statistically significant higher rate of bacteremia (P=0.004). Similarly, higher age was associated with a statistically significant higher rate of bacteremia (P&amp;lt;0.001). On the contrary, in crude analysis, no difference in the risk of bacteremia was found between sexes (P=0.9). Conclusions Bacteremia following left-sided heart valve surgery occurred in little over 2%. The majority was with Staphylococci, and half of these occurred within 30 days of the surgery. There is a continued need to optimize prophylactic strategies.

Cholecystectomy with the Hugo™ robotic-assisted surgery system: the first general surgery clinical study in Korea.

The Hugo™ Robotic-Assisted Surgery (RAS) System is an emergent device in the robotic surgery field. This study aims to describe the first general surgery-focused clinical study in Korea using the novel Hugo™ RAS System. This study was a prospective, single-center, single-arm, confirmatory clinical study conducted at Seoul National University Hospital where 20 cholecystectomies were performed. To evaluate the safety and performance of the Hugo™ RAS System the incidence of conversion to laparoscopy or open surgery, major complication (Clavien-Dindo Grade ≥ III) rate, overall complication rate, readmission rate, and reoperation rate were evaluated. All parameters were assessed within 30 days post-procedure. Any device deficiencies encountered during our initial experience and device data such as setup, console, and operative times were also reported. We confirmed that our trial achieved the primary objective with a success rate of at least 95%. This was accomplished with no conversions to other types of surgery due to serious system malfunction and with only one major complication within 24 h post-procedure. The 20 consecutively enrolled patients had a median age and BMI of 58 years old and 23.9 kg/m2, respectively. The major complication rate was 10% (2/20 patients), the overall complication rate was 15% (3/20 patients), the readmission rate was 15% (3/20 patients), and the reoperation rate was 0% (0/20 patients). None of the complications were definitively device related. The median setup, console, and operative times were 16, 17, and 55 min, respectively. The device deficiency rate was 15% (3/20 patients), but all device deficiencies were minor, occurred before the first incision, and did not present a risk to the patient. Based on our initial experience with the Hugo™ RAS System, cholecystectomy is feasible and safe. This trial is registered with ClinicalTrials.gov (NCT05715827).

A study of comparison of perioperative complications in intraperitoneal onlay mesh technique vs extended view totally extraperitoneal ventral hernia repair

Background: Abdominal hernia occurs through the layers of the abdominal wall at a weak point. Laparoscopic ventral hernia repair (LVHR) is an established treatment for ventral hernias. This study was conducted in patients who underwent e-TEP and IPOM surgery for ventral hernia to characterize postoperative pain, recovery time, and quality of life. Predefined preoperative and peri-operative factors were examined for their potential impact. Methods: A prospective study on a total of 50 patients who underwent IPOM and e-TEP for ventral hernia was conducted, who fulfilled the inclusion criteria. Patients were randomized by simple random sampling technique and were divided into two groups of 25 each (Group A- e-TEP and Group B- IPOM). Data of both groups were compared and analysed for statistical significance using Chi square test and Student ‘t’ test. Results: The eTEP approach provides benefits compared to IPOM in terms of reduced hospital stay, earlier return to work and cost effective. However, eTEP is linked to complex learning process and in the end the decision of the surgery type should be made on the basis of specific patient’s conditions, surgeon’s expertise and availability of resources Conclusions: In study we found that both surgeries were comparable, with each having some benefits over the other.

Revolutionizing endometriosis treatment: automated surgical operation through artificial intelligence and robotic vision.

Clinical limitations due to poverty significantly impact the lives and health of many individuals globally. Nevertheless, this challenge can be addressed with modern technologies, particularly through robotics and artificial intelligence. This study aims to address these challenges using advanced technologies in robotic surgery and artificial intelligence, proposing a method to fully automate endometriosis robotic surgery with a focus on interpretability, accuracy, and reliability. A methodology for fully automatic endometriosis surgery is introduced. Given the complexity of endometriosis lesions detection, they are categorized by their anatomical location to improve system interpretability. Then, three ensemble U-Net frameworks are designed to detect and localize common types of endometriosis lesions intraoperatively. A cross-training approach is employed, exploring U-Net models with diverse neural architectures-such as ResNet50, ResNet101, VGG19, InceptionV3, MobileNet, and EfficientNetB7-to develop U-Net ensemble models for precise endometriosis lesions segmentation. A novel image augmentation technique is also introduced, enhancing the segmentation models' accuracy and reliability. Furthermore, two U-Net models are developed to localize the ovaries and uterus, mitigating unexpected noise and bolstering the method's accuracy and reliability. The image segmentation models, assessed using the Intersection over Union (IoU) metric, achieved outstanding results: 97.57% for ovarian, 96.35% for uterine, and 92.58% for peritoneal endometriosis. This study proposes a fully automatic method for some common types of endometriosis surgery, including ovarian endometriomas and superficial endometriosis. This method is centered around three ensemble U-Net frameworks and a noise reduction technique using two additional U-Nets for localizing the ovaries and uterus. This approach has the potential to significantly improve the accuracy and reliability of robotic surgeries, potentially reducing healthcare costs and improving outcomes for patients worldwide.

Effectiveness of robotic metabolic and bariatric surgery in patients with BMI ≥ 50-59.9 and BMI ≥ 60 for the treatment of severe obesity in a national medical center in Mexico.

Obesity is a global health issue that significantly increases morbidity and mortality when the Body Mass Index (BMI) reaches values ≥ 50. While metabolic and bariatric surgery (MBS) is the most effective treatment for severe obesity, it carries risks. Robotic surgery is promising but not extensively studied in Mexico, which presents an opportunity for research at a National Hospital with an academic program. This retrospective study reviewed 44 patients who underwent robotic MBS using the da Vinci surgical system from January 2018 to August 2023 at Centro Médico Nacional 20 de Noviembre, ISSSTE. Data collected included surgery type, duration, complications, and weight loss metrics over 54months post-operatively. The study involved 44 patients with severe obesity including BMI ≥ 50-59.9kg/m2 for group 1 and BMI ≥ 60kg/m2 for group 2. The average initial BMI was 54.7kg/m2 for group 1 and 68kg/m2 for group 2. The average operative times for group 1 were 10.09min for docking, 86.23min for robotic console time, and 95.73min for total intraoperative time. Group 2 had average times of 9.80min for docking, 82.4min for robotic console time, and 92.2min for total intraoperative time. Follow-up showed significant weight loss initially, with weight recurrence after 24months due to different factors. No serious complications or mortality were observed. Robotic MBS at a national academic medical center in Mexico shows promising outcomes for patients with BMI ≥ 50-59.9 and BMI ≥ 60, with significant weight and BMI improvements at 54month follow-up. Further studies with larger cohorts and longer follow-up are needed to strengthen these findings.

A Retrospective Study on Endoscopic Surgery for the Treatment of Paravertebral Abscess in Spinal Tuberculosis Patients.

Spinal tuberculosis (TB) remains a significant global health concern, necessitating the development of innovative treatment strategies. This clinical study aimed to evaluate the efficacy and safety of endoscopic debridement as a minimally invasive approach for treating paravertebral abscesses in patients with spinal tuberculosis. A total of 52 patients diagnosed with paravertebral tuberculosis abscesses were enrolled in this retrospective study. Patients were assigned to two groups: the endoscopic debridement group (n = 30) and the conventional open surgery group (n = 22), based on the type of surgery they received. Clinical outcomes were assessed at baseline, post-treatment, and follow-up visits at regular intervals, including surgery time, intraoperative blood loss, total hospital stay duration, pain relief, and neurological improvement. The results of this study demonstrate that endoscopic debridement is a highly effective treatment for paravertebral abscesses in patients with spinal TB. Patients in the endoscopic debridement group experienced significant improvements in surgery time, intraoperative blood loss, total hospital stay duration, pain relief, and neurological improvement compared to those in the conventional open surgery group. Additionally, the endoscopic approach resulted in fewer complications, such as wound infections and postoperative instability, with no cases of recurrence observed during the follow-up period. Therefore, this clinical study highlights the potential of endoscopic debridement as a safe and effective treatment modality for spinal tuberculosis. The technique not only effectively eliminates infected tissue but also ensures faster patient recovery and reduces postoperative complications. Additional research and long-term follow-up studies are necessary to confirm the long-term effectiveness and safety of endoscopic debridement as the standard treatment for spinal tuberculosis.

Postoperative opioid use in Norway—a population-based observational study on patterns of long-term use

BackgroundThe utilization patterns of opioid analgesics and the proportion of long-term opioid use after surgery in Norway is largely unknown.MethodsThis study aimed to estimate the proportion of one-year long-term prescription opioid use among all Norwegian postoperative opioid users. Complete data from central health registries (NPR, NorPD, Statistics Norway, CoDR) were linked via the personal identification number unique to all citizens. The study period was January 1st 2010 until December 31st 2019. Long-term opioid use was defined as at least two opioid dispensings within two subsequent 90-day periods, with a minimum average use of 10 MME/day for the first 90 days.ResultsThe study population consisted of 693 495 post-operative opioid users (53.6% women), whereof 73.2% had not used opioids the year before surgery (new users). Among the postoperative opioid users, 3.8% were one-year long-term opioid users. The corresponding figures for new and previous opioid users were 0.4% and 13.1%, respectively. The highest proportions of long-term opioid use were found after transluminal endoscopy, eye surgery and assessments related to surgical procedures. In previous opioid users, the proportion of one-year long-term use was higher among women than men in all age groups, a difference that increased with age.ConclusionsThe proportion of postoperative long-term opioid use in Norway is generally low. We detected higher proportions of long-term opioid use after certain types of surgery, but our crude surgery definition warrants further examination. Previous opioid users pose a particular challenge in the management of postoperative pain.Trial registrationThe study used national health registry data from the period 2010–2019. A pre-registered analysis plan is available at Open Science Framework.

Comparison of surgical performance using articulated (ArtiSential®) and conventional instruments for colorectal laparoscopic surgery: A single-centre, open, before-and-after, prospective study.

Rigid surgical instruments limit movement whereas articulated instruments offer better control in small spaces and allow for intuitive and ergonomic movements. However, the effectiveness of the use of articulated instruments in improving colorectal laparoscopic outcomes remains unclear. The aim of this work was to determine whether colorectal laparoscopic surgical proficiency improved when multijoint instruments were used instead of conventional ones. We enrolled 70 consecutive patients (n = 20 for conventional instruments) aged 19-80 years who underwent elective laparoscopic surgery for colorectal diseases. Unedited surgery videos were validated using the modified Global Operative Assessment of Laparoscopic Skills (mGOALS) scale. Learning curves were analysed using a cumulative sum control chart for mGOALS grades. The surgery type, length of hospital stay and 30-day postoperative complication rates were comparable between the groups, and the surgeon's mGOALS grades were similar (p = 0.190). However, in the articulated group, the scores were significantly higher for depth perception (p = 0.012) and tissue-handling domains (p = 0.046), while surgical duration was significantly shorter and intraoperative blood loss was significantly lower (p = 0.022), compared with those in the conventional (p = 0.002) group. Learning curve findings indicated that the first 10 and subsequent 40 surgeries in the articulated group were within the inexperienced and experienced phases, respectively. The mGOALS score in the experienced phase improved in the articulated group compared with that in the conventional group (p = 0.036). The use of articulated instruments in laparoscopic colorectal surgery showed potential benefits. Further studies are needed to confirm these findings.

Mapping the landscape of machine learning models used for predicting transfusions in surgical procedures: a scoping review

Massive transfusion of blood products poses challenges in determining the need for transfusion and the appropriate volume of blood products. This review explores the use of machine learning (ML) models to predict transfusion risk during surgical procedure, focusing on the methodology, variables, and software employed to predict transfusion. This scoping review investigates the development and current state of machine learning models for predicting transfusion risk during surgical procedure, aiming to inform physicians about the field’s progress and potential directions.The review was conducted using the databases Cochrane, Embase, and PubMed. The search included keywords related to blood transfusion, statistical models, and surgical procedures. Peer-reviewed articles were included, while literature reviews, case reports, and non-human studies were excluded.A total of 40 studies met the inclusion criteria. The most frequently studied biological variables included haemoglobin, platelet count, international normalized ratio (INR), activated partial thromboplastin time (aPTT), fibrinogen, creatinine, white blood cells, and albumin. Clinical variables of importance included age, sex, surgery type, blood pressure, weight, surgery duration, american society of anesthesiology (ASA) status, blood loss, and body mass index (BMI). The software employed varied, with Python, R, SPSS, and SAS being the most commonly used. Logistic regression was the predominant methodology used in 20 studies.Our scoping review highlights the need for improved reporting and transparency in methodology, variables, and software used. Future research should focus on providing detailed descriptions and open access to codes of respective models, promoting reproducibility, and enhancing the clinical relevance of transfusion risk prediction models.

Clinical Outcomes and Prognostic Factors for R0 Resected Colorectal Cancer with Synchronous Peritoneal Metastasis: A Retrospective Study.

Peritoneal metastasis indicates a poor prognosis in patients with colorectal cancer (CRC). Studies have shown improved prognosis in patients after removal of peritoneal dissemination, and this surgery is recommended if not excessively invasive. The aim of this study was to examine clinical outcomes and prognostic factors for R0 resected CRC with synchronous peritoneal metastasis. We analyzed data retrospectively from 250 patients with stage IV CRC who underwent R0 resection at our hospital. The patients were divided into three groups according to the type of surgery: non-resected (N), palliative primary tumor resection (P), and R0 resection (R0) groups. Overall survival (OS) and recurrence-free survival (RFS) were investigated and clinicopathological parameters were analyzed for prognostic significance. The 3-year OS was 57.2% in the R0 group. The R0 group had a significantly higher 3-year OS than that in the other groups (p < 0.0001). Multivariate analysis revealed that histological type, lymphatic and venous invasion, liver metastasis, R0 resection, and perioperative chemotherapy were independent prognostic factors. The 5-year RFS in the R0 group was 26.5%. Multivariate analysis revealed that the number of peritoneal metastases and surgical procedure were independent prognostic factors. Laparoscopic surgery had better 5-year RFS in the R0 group compared with that in the open surgery group (p = 0.0044). R0 resection of colorectal cancer with synchronous peritoneal metastasis should be considered for improving long-term survival. The laparoscopic approach for this disease is another promising method to prolong survival in patients with R0 resection.

The Stockholm Spinal Cord Uro Study: Changing patterns of urological surgery in a regional prevalence group through 50 years - Outcomes and lessons learned.

To examine the number and types of urological surgical procedures carried out in a regional prevalence population of patients with traumatic spinal cord injury (SCI) during five decades, evaluate objective and patient-reported outcomes and to consider lessons learned for further improvement of surgical treatment in this patient group. In a cross-sectional study of 412 patients with traumatic SCI, one-third had undergone urological surgery through a period of up to 50 years. Data on types of surgery, complications, follow-up and outcomes were collected in a retrospective review of patient files. S-creatinine, S-cystatin-C, renal ultrasound and a questionnaire regarding complications during the preceding year were assembled as part of a yearly follow-up. Descriptive statistics were calculated. Logistic regression was used to determine risk profiles for the incidence of urological surgery. A total of 137 patients had undergone 262 urological surgical interventions. The incidence was highest amongst persons with a cervical-thoracic neurological level of spinal cord lesion and during the first 2 years after SCI. Surgery for urinary stones constituted 29% of all procedures. One-fourth of the patients had undergone 47% of all procedures, notably urinary diversion and ensuing complications, implants and revisions, repeated stone interventions or bladder outlet procedures. After reconstructive surgery functional outcomes and patient-reported satisfaction were generally favourable, but long-term signs of renal complications were frequent. Urological surgery after SCI involves imperative as well as reconstructive procedures, some of which are challenging and call for centralisation to devoted teams. Prospective studies of reconstructive urology are warranted, including more extensive patient-reported outcomes.

Shared decision-making for patients with vaccine-related concerns of blood transfusion: A single institution experience.

Some patients express concerns regarding receipt of allogeneic blood transfusions from donors potentially vaccinated against SARS-CoV-2 (COVID-19). However, limited information exists about patients' expression of these concerns or how to address them during the blood transfusion consent process. In this study, we describe our experience of working collaboratively with patients with vaccine-related transfusion concerns prior to elective surgery, summarizing treatment decisions and clinical outcomes. This observational descriptive study includes patients seen in our Bloodless Medicine and Surgery clinic between June 2022 and June 2024 for vaccine-related transfusion concerns prior to elective surgery. A shared decision-making framework was employed to foster conversation, share information, provide reassurance, reconcile conflict, and match preferences with available care options. Patient characteristics, treatment decisions, and surgical outcomes were reviewed and summarized. Thirty-five patients were included, with median (1st, 3rd quartile) age of 61 (53, 69) years. Cardiac surgery was the most common type of surgery (29%). Twelve patients (34%) were anemic preoperatively, and all received preoperative treatment. After discussion with a Bloodless Medicine specialist, 24 (68.6%) decided to consent to the use of all blood products, 5 (14.3%) accepted only red blood cells, and 6 (17.1%) declined all blood products. Among 28 patients undergoing surgery, only 4 (14%) received allogeneic transfusion perioperatively. Many patients concerned about the vaccination status of blood donors may ultimately consent to allogeneic blood products after shared decision-making with a Bloodless Medicine specialist, highlighting the importance of patient empowerment and collaborative care.

Necrotizing enterocolitis in term infants with congenital heart disease and preterm infants after surgery

Background: The purpose of this study was to report and compare the surgical outcomes of preterm-related necrotizing enterocolitis (PNEC) and congenital heart disease (CHD)-related necrotizing enterocolitis (CDNEC). Materials and Methods: Preterm infants without CHD and term infants with CHD who developed NEC and needed surgery were included in this cohort study between 2018 and 2021 at our university-affiliated hospital. A board-certified pediatric cardiologist examined all the patients with echocardiographic and cardiac examinations to diagnose CHD, and a pediatric surgeon evaluated the neonates for surgical indications. Patient characteristics, pregnancy history, and surgical and mortality outcomes were collected from the infants’ medical records. Results: Forty infants with NEC were included. The CDNEC and PNEC groups consisted of 18 and 22 infants, respectively. Although the disease-specific mortality rate was higher in the CDNEC group than in the PNEC group, the difference was insignificant (55.5% and 40.9%, respectively, P=0.36). There was no statistically significant difference in the time of NEC occurrence, location, type of surgery, or indications for surgery between the two groups. Conclusion: Despite the pathophysiologies of CDNEC and PNEC being different, the characteristics, pregnancy history, surgical, and mortality outcomes of these two types are similar in infants who undergo surgical treatment.

A 10-year Retrospective Clinical Study to Identify Risk Indicators for Peri-Implant Bone Loss and Implant Failure.

To evaluate long-term survival and success of dental implants and evaluate indicators affecting the long-term outcome. Implant survival, success and crestal bone loss (BL) over time were evaluated. For covariates at patient level, Kaplan-Meier estimates of implant survival were compared between groups with the log-rank test. Observed mean bone loss (MBL) was plotted as a function of time. Cumulative frequencies of BL were plotted for different post-op times. Uni- and multivariate analysis was performed. Simple linear mixed and multiple linear mixed models for BL at 1, 5 and 10 years were fitted. 407 patients (221 women, 186 men; mean age 64.86 years (range 28-92, SD 10.11)), with 1482 implants, responded. Absolute implant survival was 94.74%; MBL was 0.81 mm (SD 1.58, range 0.00-17.00) after an average follow-up of 10.66 years (range 10-14, SD 0.87). Implant survival was influenced on implant level by smoking, implant width and early bone loss (EBL) > 0.5 mm; on patient level by a history of periodontitis. Indicators influencing MBL after the 1st year were abutment height, type of surgery and implant width, while after 5 and 10 years of function were abutment height, EBL > 0.5 mm and smoking. Implant survival was significantly affected by a history of periodontitis on patient level and by smoking, implant width and EBL > 0.5 mm on implant level. Late bone loss was significantly affected by abutment height, EBL > 0.5 mm and smoking. B670201524796.

Comprehensive Analysis of Thyroidectomy-Related Complications: A Single-Center Perspective.

Background Thyroid surgeries have become so common that they are performed for both benign and malignant conditions of the thyroid. However, hypoparathyroidism and recurrent laryngeal nerve (RLN) injury may turn out to be a nightmare, complicating the surgical outcome. This study will, therefore, attempt to assess the complications related to different types of thyroid surgeries in order to identify the risk factors involved. Methodology This is a report on an analytical study done in a tertiary care center for a span of 12 months on 60 patients aged between 18 and 80 who were subjected to thyroidectomy. The preoperative evaluation consisted of acomplete ear, nose, and throat (ENT) examination, indirect laryngoscopy, routine blood tests, thyroid function tests, neck ultrasound, and fine-needle aspiration cytology (FNAC). The surgical interventions carried out were total thyroidectomy (TT), near-TT, sub-TT, and hemithyroidectomy (HT). Postoperative complications are followed for at least six months. Results The study identified postoperative complications in 21 patients (35%), with hypoparathyroidism being the most prevalent, affecting nine patients (15%). This complication rate is noteworthy, especially when compared to national or international averages, which typically report postoperative complication rates ranging from 10% to 30% after thyroid surgeries. RLN injury occurred in five patients (8%), while other complications, such as hematoma and wound infection, were observed in three patients (5%) and two patients (3%), respectively. Temporary hypoparathyroidism was observed in 15 patients (25%) who underwent TT, indicating a significant increase in the incidence of this complication compared to other surgical procedures. Conclusion It seems that there is an area where very precise surgical practice and extensive workup before surgery must be in place to prevent complications arising from thyroid surgeries. Continuous observation and planned follow-up should be as crucial for better outcome of the patient and timely management of complications arisen postoperatively.

Surgery for facial palsy in the hands of otorhinolaryngologists: a population-based study.

Modern facial surgery can improve eye closure and address facial functional and emotional expression disabilities in case of severe acute facial paralysis with low probability of recovery and in cases of chronic flaccid facial paralysis. Reports on outcome typically originate from specialized tertiary care centers, whereas population-based data from routine care beyond specialized centers is sparse. Therefore, patients' characteristics, surgical techniques, postoperative complications, and patients' satisfaction with the final outcome were analyzed for all inpatients with facial paralysis undergoing facial surgery in Thuringia, a federal state in Germany, between 2006 and 2022. 260 patients (female 41.5%; median age 65 years) were included. On average, the surgery rate was higher for men than for women (0.83 ± 0.39 versus 0.58 ± 0.24 per 100,000 population per year). For first surgery, static procedures were dominating (67.3%), followed by dynamic reconstruction (13.8%), and combined static and dynamic reconstructions (13.5%). The most frequent type of surgery was upper lid weight loading (38.5%), hypoglossal-facial jump nerve suture (17.3%), and facial-facial interpositional graft suture (16.9%). Bleeding/hematoma formation needing revision surgery was the most frequent complication (6.2%). Overall, 70.4% of the patients were satisfied with the final result. The satisfaction was higher if the target was to improve eye closure (65.2%) or to improve upper face function (65.3%) than to improve the lower face function (53.3%). If facial nerve reconstruction surgery and/or upper lid weight placement was performed, the satisfaction was significantly higher. If revision surgery was needed to improve the result, the satisfaction was significantly lower.
