An additional gastrojejunostomy may reduce the incidence of moderate and severe delayed gastric emptying after distal segmental duodenectomy for gastrointestinal stromal tumors.

To investigate whether an additional gastrojejunostomy reduces the incidence of delayed gastric emptying (DGE) following a distal segmental duodenectomy for duodenal and proximal jejunal gastrointestinal stromal tumors (GIST). This retrospective review of the GIST database at Peking University Cancer Hospital included 50 patients who underwent distal segmental duodenectomies for primary GIST in the duodenum or proximal jejunum within 20cm of Treitz's ligament between January 2008 and December 2023. The patients were divided into two groups: non-bypass (without gastrojejunostomy) and bypass (with gastrojejunostomy and Braun's jejunojejunostomy). Perioperative characteristics and postoperative complications were analyzed. Among the 50 patients, 27 underwent duodenojejunostomies without gastrojejunostomies and 23 with gastrojejunostomies and Braun's jejunojejunostomies. The incidence of grade B-C DGE was significantly lower in the bypass group (43.5% vs. 74.1%, p = 0.028). In addition, non-bypass surgery was an independent risk factor for increased grade B-C DGE (OR 3.67, 95% CI 1.07-12.64, p = 0.039). The bypass group showed a trend towards a shorter postoperative hospital stay (median: 14 days, range: 10-56) compared to the non-bypass group (median: 28 days, range: 6-75), but this difference did not reach statistical significance (p = 0.070). Operative time (min) was significantly longer in the multi-visceral resection group (381.0 ± 108.8 vs. 227.3 ± 87.6, p < 0.001), for tumors ≥ 6.3cm compared to < 6.3cm (337.0 ± 116.4 vs. 228.3 ± 99.8, p = 0.002), and in patients with positive preoperative symptoms versus asymptomatic patients (319.9 ± 118.0 vs. 210.2 ± 90.3, p = 0.031). The addition of gastrojejunostomy and Braun's jejunojejunostomy in distal segmental duodenectomy can reduce the incidence of grade B-C DGE, potentially facilitating timely adjuvant imatinib therapy. Future multicenter studies are needed to confirm these findings.

Oncological safety of fertility preservation treatment in ovarian cancer: A Spanish multicenter study.

To assess the safety of fertility-sparing treatments for early-stage ovarian cancer in women younger than 40 years old. We performed a retrospective multicenter study including women aged 18-40 years diagnosed with early-stage (FIGO I-II) ovarian cancer in 55 Spanish hospitals, from January 2010 to December 2019. Benign and borderline tumors were excluded, as well as advanced stages (FIGO III-IV). All perioperative characteristics and follow-up data were collected and analyzed. Standard staging surgery (SSS) was compared with fertility-sparing surgery (FSS) in terms of oncological outcomes. In all, 366 women were included; 327 (89.3%) were stage I. Among all patients, 216 (59%) underwent SSS and 150 (41%) FSS. Up to 208 (56.8%) patients did not have children, but only 12 (3.2%) had oocyte preservation before treatment. Patients in the FSS group compared with the SSS group showed a non-significant difference in recurrences (8% vs. 9.3%, respectively; P < 0.711) and deaths (1.3% vs. 4.8%, respectively; P = 0.211) during the follow-up. No significant differences were found between epithelial and non-epithelial ovarian cancer both in recurrences (7.1% vs. 8.8%, respectively; P = 0.771) and in deaths (1.4% vs. 1.3%, respectively; P = 1) among patients who underwent FSS. FSS seems a safe option for treatment of early-stage ovarian cancer in patients who want to preserve fertility, either for epithelial and non-epithelial histology.

Aged hippocampal single-cell atlas screening unveils disrupted neuroglial system in postoperative cognitive impairment.

Glia-neuron interaction is a crucial feature in aged hippocampus during the occurrence of postoperative cognitive impairment. However, the regulatory effects of microglia, astrocytes, and oligodendrocytes in this glia-neuron interaction, the potential mechanisms and gene targets are still to be elucidated. Here, single-cell RNA sequencing was performed to detect the perioperative genomic expression characteristics of neuroglial system in the hippocampus of aged mice, and to investigate the potential cross-cellular mechanisms and valuable treatment options for glia-neuron interaction-related cognitive impairment. We found that postoperative neurons and glia cells exhibited protein dysmetabolism and mitochondrial electron misrouting. Impaired autophagy and circadian rhythm worsened microglia activation/neuroinflammation, and exacerbated these metabolic alterations. Reactive microglia also aggravated astrocyte and oligodendrocyte cytotoxicity through the PGD2/DP and complement pathways, altering glutamate level and synaptic function via the "tripartite synapses" model, and affecting neuronal myelination. Ligand-receptor communication also indicated these synaptic and axonal dysfunctions via enhanced MDK and PTN pathways. Additionally, we found that anesthetic dexmedetomidine hold therapeutic potential within the disrupted neuroglial system. It enhanced neuronal metabolic rebalance (Atf3-related) and reduced neuroinflammation from a multicellular perspective, therefore improving postoperative cognitive impairment. Together, our study proposes an aged hippocampal cell atlas and provides insights into the role of disrupted glia-neuron cycle in postoperative cognitive impairment. Our findings also elucidate the therapeutic potential and mechanism of dexmedetomidine intervention.

Modified kinematic alignment better restores plantar pressure distribution than mechanical alignment in total knee arthroplasty: a randomized controlled trial.

Kinematic alignment (KA) in the short to medium term clinical outcomes is superior to the mechanical alignment (MA), but whether it will improve patients' postoperative gait is still controversial. Understanding whether and how KA influences postoperative gait mechanics could provide insights into optimizing alignment philosophy to improve functional outcomes. To investigate the impact of KA versus MA in total knee arthroplasty (TKA) on the operated and contralateral native lower limbs by analyzing plantar pressure distribution during walking gait. This study was designed as a secondary analysis from a randomized controlled trial. Thirty-seven patients were included, nineteen underwent KA-TKA and eighteen underwent MA-TKA, each with a native knee in the contralateral limb. Pressure-sensitive insoles were used to collect plantar pressure distribution of both limbs simultaneously during walking defined as medial-lateral load ratio (MLR). Perioperative characteristics including radiographic metrics (Hip-Knee-Ankle angle (HKA), mechanical lateral distal femoral angle (mLDFA), and mechanical medial proximal tibial angle (mMPTA) and clinical outcomes (Oxford Knee Scores (OKS)) were compared between the two groups pre-operatively and 2-year postoperatively. Significant differences were found in postoperative radiographic metrics, with KA showing better OKS 1 year postoperatively (p = 0.021), lower mean HKA (p = 0.009) and mMPTA (p < 0.001). Other perioperative characteristics were similar between groups. In the pedobarographic analysis, the MA group demonstrated greater medial pressure distribution in forefoot compared to both the KA group (p < 0.001) and the contralateral native knee (p = 0.002). Besides, the MA group revealed a more lateral pressure distribution in rearfoot compared to the KA group (p = 0.007) and the contralateral native knee (p = 0.001). While there was no significant difference between KA and native group (p = 0.064 and p = 0.802, respectively). KA offered advantages over MA in restoring a more physiologic plantar pressure distribution at two years postoperatively. These results underscore the potential clinical benefits of adopting KA techniques in TKA procedures.

Tarsal Coalition Resection in Children: Is it Effective?

Tarsal coalitions in children are a group of disorders that typically present as a rigid flatfoot deformity. Operative treatment generally consists of resecting the coalition alone or resection plus flatfoot reconstructive procedures. The purpose of this study was to evaluate the rate and risk factors for complications, including infection, recurrence, and reoperation, following the surgical management of tarsal coalitions in children. This is a retrospective cohort study on the surgical outcomes of pediatric tarsal coalitions alone or in combination with adjunctive procedures. This study was conducted between 01/01/2008 and 12/31/2019 and utilized electronic health records and chart review was performed to describe patient demographic, clinical, perioperative characteristics, and whether patients have subsequent foot and ankle procedures after the index resection surgery. The study cohort included 165 feet belonging to 144 patients. The age range at time of surgery was 12 years of age (11-14). Of the 165 feet, 18 (10.9%) experienced a postoperative complication, including six infections of which two required reoperation, six recurrences all requiring reoperation, and six reoperations not due to recurrence. Patients with a postoperative complication demonstrated increased age (13.9 years vs 12.4 years, p=0.007), obesity (33.3% vs 13.6%, p=0.026), and/ or preoperative hindfoot valgus deformity (33.3% vs 7.5%, p=0.004). The overall postoperative complication rate was 10.9%. Results of this study provided important information for providers as they discuss different treatment approaches and anticipated outcomes with patients and their families.

The Evolution of Unicoronal Synostosis Correction: Long-Term Aesthetic Outcomes of Fronto-Orbital Distraction Versus Traditional Advancement.

This study compares the long-term aesthetic outcomes of patients with unicoronal synostosis (UCS) who underwent fronto-orbital distraction osteogenesis (FODO) versus traditional fronto-orbital advancement and remodeling (FOAR). Patients treated for nonsyndromic UCS from 2009 to 2023 were retrospectively reviewed. Perioperative and complication characteristics were compared between all patients who underwent FOAR, open FODO, and endoscopic-assisted FODO ("endo-FODO"). Aesthetic outcomes at greater than five years postoperatively were compared between patients who underwent FODO and a contemporaneous cohort of age-matched controls who underwent FOAR. Differences between pre- and postoperative periorbital symmetry ratios, canthal tilt symmetry, orbital dystopia angle (ODA), and frontal bossing angle were calculated, with positive differences representing postoperative improvement. Forty-one patients were treated at a median age of 9.7, 5.4, and 5.4 months in the FOAR, open FODO, and endo-FODO groups, respectively. Among 28 patients photographed at a median of 6.3 years postoperatively, the FODO cohort demonstrated greater margin-to-reflex distance 1 symmetry (6.5 [-9.3, 0.0] vs. -13.9 [-22.9, -11.5], p=0.010) and canthal tilt symmetry (0.9° [0.2°, 2.9°] vs. 3.3° [2.3°, 5.3°], p=0.004) postoperatively as well as ODA correction (5.4° [4.0°, 7.5°] vs. 3.0° [2.5°, 4.4°], p=0.027) compared to the FOAR cohort. Fewer patients in the FODO cohort exhibited temporal hollowing postoperatively compared to the FOAR cohort (14% vs. 71%, p=0.002). Compared to FOAR, FODO was associated with greater periorbital symmetry, greater orbital dystopia correction, and reduced temporal hollowing in the long-term. Follow-up to cranial maturity is needed to adequately compare the two techniques.

Minimally Invasive Transforaminal Versus Lateral Lumbar Interbody Fusion for Degenerative Spinal Pathology: Clinical Outcome Comparison in Patients With Predominant Back Pain.

Retrospective review. To compare perioperative and postoperative clinical outcomes between minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) and lateral lumbar interbody fusion (LLIF) in patients presenting with predominant back pain. Two popular techniques utilized for lumbar arthrodesis are MIS-TLIF and LLIF. Both techniques have reported high fusion rates and suitable postoperative clinical outcomes. Scarce literature exists, however, comparing these 2 common fusion techniques in a subset population of patients presenting with predominant back pain preoperatively. A retrospective review of lumbar procedures performed between November 2005 and December 2021 was conducted using a prospectively maintained single-surgeon database. Inclusion criteria were set as primary, elective, single, or multilevel MIS-TLIF or LLIF procedures for degenerative spinal pathology in patients with predominant preoperative back pain [visual analog scale (VAS) back pain preoperative score > VAS leg preoperative score]. Patients undergoing a revision procedure, single-level procedure at L5-S1, or surgery indicated for infectious, malignant, or traumatic etiologies were excluded. In addition, patients with VAS leg preoperative scores ≥ to VAS back preoperative scores were excluded. Patient demographics, perioperative characteristics, postoperative complications, and patient-reported outcome measures (PROMs) were collected. PROMs included VAS for back and leg pain, Oswestry Disability Index (ODI), and Short Form-12 (SF-12) Item Survey Mental (MCS) and Physical (PCS) Composite Scores with all values collected at the preoperative, 6-week, 12-week, 6-month, 1-year, and 2-year follow-up time point. Patients were grouped into 2 cohorts, depending on whether a patient underwent a MIS-TLIF or LLIF. Demographic and perioperative characteristics were compared between groups using χ2 and Student t test for categorical and continuous variables, respectively. Mean PROM scores were compared between cohorts at each time point utilizing an unpaired Student t test. Postoperative improvement from preoperative baseline within each cohort was assessed with paired samples t test. Achievement of minimum clinical important difference (MCID) was determined by comparing ΔPROM scores to previously established threshold values. MCID achievement rates were compared between groups with χ2 analysis. Statistical significance was noted as a P value <0.05. Eligible study cohort included 153 patients, split into 106 patients in the MIS-TLIF cohort and 47 patients in the LLIF cohort. The mean age was 55.9 years, the majority (57.5%) of patients were males, the mean body mass index was 30.8kg/m2, and the majority of the included cohort were nondiabetic and nonhypertensive. No significant demographic differences were noted between cohorts. The MIS-TLIF cohort had a significantly greater proportion of patients with preoperative spinal pathology of recurrent herniated nucleus pulposus, whereas a significantly greater proportion of patients in the LLIF cohort demonstrated isthmic spondylolisthesis (P < 0.046, all). No significant differences were noted between cohorts for operative duration, estimated blood loss, 1-year rate of arthrodesis, postoperative length of stay, postoperative VAS pain scores on postoperative day 0 or 1, and postoperative narcotic consumption on postoperative day 0 or 1. Patients in the LLIF cohort showed greater rates of postoperative ileus (4.3% vs 0.0%). No other significant differences were noted between cohorts for postoperative complications. Between cohorts, preoperative PROM scores did not significantly differ. The following significant postoperative mean PROM scores were demonstrated: VAS back at 12 weeks and ODI at 12 weeks with both mean scores favoring the LLIF cohort. The MIS-TLIF cohort reported significant improvement from preoperative baseline to the 2-year time point for all PROMs collected at all individual postoperative time points except SF-12 MCS at 6 weeks (P < 0.0, all). LLIF cohort reported significant improvement from preoperative baseline to the 1-year time point for all PROMs collected at all individual postoperative time points except for ODI at 6 weeks, 1 year, and 2 years, SF-12 MCS at 6 weeks and 2 years, and SF-12 PCS at 2 years(P < 0.042, all). The majority of patients in both cohorts achieved overall MCID for VAS back, VAS leg, ODI, and SF-12 PCS. A significantly greater proportion of patients in the LLIF cohort achieved MCID for SF-12 PCS at 12 weeks (94.4% vs 61.1%; P < 0.008). Patients with predominant back pain undergoing MIS-TLIF or LLIF for degenerative spinal pathology demonstrated similar 2-year mean clinical outcomes for physical function, disability, leg pain, and back pain. At the 12-week time point, mean outcome scores for back pain and disability favored the lateral approach with concurrent higher rates of MCID achievement for physical function at that time point.

Opioid use patterns following discharge from elective colorectal surgery: a prospective cohort study.

Opioid overprescription after colorectal surgery can lead to adverse events, persistent opioid use, and diversion of unused pills. This study aims to assess the extent to which opioids prescribed at discharge after elective colorectal surgery are consumed by patients. This prospective cohort study included adult patients (≥ 18yo) undergoing elective colorectal surgery at two academic hospitals in Montreal, Canada. Patients completed preoperative questionnaires and data concerning demographics, surgical details, and perioperative care characteristics (including discharge prescriptions) were extracted from electronic medical records. Self-reported opioid consumption was assessed weekly up to 1-month post-discharge. The total number of opioid pills prescribed and consumed after discharge were compared using the Wilcoxon signed-rank test. Negative binomial regression was used to identify predictors of opioid consumption. We analyzed 344 patients (58 ± 15years, 47% female, 65% laparoscopic, 31% rectal resection, median hospital stay 3days [IQR 1-5], 18% same-day discharge). Most patients received a TAP block (67%). Analgesia prescription at discharge included acetaminophen (92%), NSAIDs (38%), and opioids (92%). The quantity of opioids prescribed at discharge (median 13 pills [IQR 7-20]) was significantly higher than patient-reported consumption at one month (median 0 pills [IQR 0-7]) (p < 0.001). Overall, 51% of patients did not consume any opioids post-discharge, and 63% of the prescribed pills were not used. Increased opioid consumption was associated with younger age (IRR 0.99 [95%CI 0.98-0.99]), higher preoperative anxiety (1.02 [95%CI 1.00-1.04]), rectal resections (IRR 1.45 [95%CI 1.09-1.94]), and number of pills prescribed (1.02 [95%CI 1.01-1.03]). A considerable number of opioid pills prescribed at discharge after elective colorectal surgery are left unused by patients. Certain patient and care characteristics were associated with increased opioid consumption. Our findings indicate that post-discharge analgesia with minimal or no opioids may be feasible and warrants further investigation.

Patients undergoing emergent surgery for type A intramural hematomas or type A aortic dissections have similar outcomes

ObjectiveDespite key differences in pathological processes, both Intramural Hematomas and Aortic Dissections are Acute Aortic Syndromes repaired with similar surgical technique. The objective of this study was to determine differences in surgical outcomes between patients with Intramural Hematoma versus Type A Aortic Dissection undergoing Ascending Aortic Arch repair.MethodsThis retrospective review of prospectively collected data included all patients with acute Intramural Hematoma or Type A Aortic Dissection who underwent emergent Ascending- or Arch Repair from January 2018 to May 2023 at a single academic institution. Primary outcomes included intraoperative mortality, 30-Day mortality, and postoperative stay. Secondary outcomes included postoperative complications. Outcomes were analyzed using Chi-squared, Fisher’s Exact, and t-tests, with significance set at p < 0.05.ResultsA total of 107 patients were included, 27 of whom (25%) had Intramural Hematoma and 80 (75%) had Type A Aortic Dissection. There were no differences in preoperative characteristics such as age, gender, and comorbidities, and no differences in perioperative characteristics such as case length, cardiopulmonary bypass, aortic cross-clamp, and circulatory arrest times. When comparing postoperative outcomes, there was a higher rate of postoperative pericardial effusions requiring pericardial window in the Intramural Hematoma cohort compared to the Aortic Dissection cohort (15% [n = 4] vs. 3% [n = 2]; p = 0.02). There were no differences in other primary outcomes such as intraoperative mortality, 30-Day mortality, and postoperative length of stay. There were also no differences in the rates of postoperative complications such as bleeding requiring reoperation, cerebrovascular accident, atrial fibrillation, pleural effusion requiring thoracentesis, and surgery-related Emergency Department visits.ConclusionsOur analysis demonstrates similar outcomes for patients undergoing Ascending Aortic Arch repair between patients with Intramural Hematoma and Type A Aortic Dissection. Despite the higher rate of required postoperative pericardial windows in the Intramural Hematoma cohort, the overall primary outcomes remained comparable. These findings better elucidate the standard of care for patients with acute Intramural Hematoma undergoing Ascending Aortic Arch repair.

The Safety and Feasibility of Ambulatory Minimally Invasive Partial Nephrectomy: A Systematic Review and Meta-Analysis.

Purpose: Emerging evidence supports the use of minimally invasive partial nephrectomy (MIPN) in ambulatory settings. We conducted a systematic review and meta-analysis to evaluate differences in perioperative characteristics, complication/readmission rates and satisfaction/cost data between ambulatory and standard-length discharge (SLD) MIPN. Methods: This study was prospectively registered in PROSPERO (CRD42023429854). A systematic literature search of PubMed, Embase, and Web of Science databases was conducted, including studies comparing ambulatory MIPN vs SLD MIPN for patients with renal masses. Studies were assessed for quality using the Methodological Index for Non-Randomized Studies score. Meta-analysis was performed for comparative studies, and non-comparative studies were included narratively. Results: Eleven studies were included with a pooled population of 20,548 patients, of which 1,419 (7%) had a length of stay less than 1 day and were considered the ambulatory group. There were no significant differences in the total complication rates (RR: 0.50, 95% CI: 0.24, 1.04; p = 0.06) or 30-day readmission rates (RR: 0.87, 95% CI: 0.56, 1.35; p = 0.53) between the ambulatory and SLD groups. There were fewer >3 Clavien-Dindo complications in the ambulatory group (RR: 0.34, 95% CI: 0.19, 0.59; p = 0.0002). Few studies reported average health care cost and patient satisfaction. Conclusions: In appropriately selected patients, ambulatory MIPN is safe and feasible. Future studies are needed to quantify cost and patient satisfaction differences and further identify appropriate patient selection criteria for ambulatory MIPN.

Predictors of Durable Remission After Successful Surgery for Cushing Disease: Results From the Multicenter RAPID Registry.

Cushing disease (CD) affects mortality and quality of life along with limited long-term remission, underscoring the need to better identify recurrence risk. The identification of surgical or imaging predictors for CD remission after transsphenoidal surgery has yielded some inconsistent results and has been limited by single-center, single-surgeon, or meta-analyses studies. We sought to evaluate the multicenter Registry of Adenomas of the Pituitary and Related Disorders (RAPID) database of academic US pituitary centers to assess whether robust nonhormonal recurrence predictors could be elucidated. Patients with treated CD from 2011 to 2023 were included. The perioperative and long-term characteristics of CD patients with and without recurrence were assessed using univariable and multivariable analyses. Of 383 patients with CD from 26 surgeons achieving postoperative remission, 288 (75.2%) maintained remission at last follow-up while 95 (24.8%) showed recurrence (median time to recurrence 9.99 ± 1.34 years). Patients with recurrence required longer postoperative hospital stays (5 ± 3 vs 4 ± 2 days, P = .002), had larger average tumor volumes (1.76 ± 2.53 cm 3 vs 0.49 ± 1.17 cm 3 , P = .0001), and more often previously failed prior treatment (31.1% vs 14.9%, P = .001) mostly being prior surgery. Multivariable hazard prediction models for tumor recurrence found younger age (odds ratio [OR] = 0.95, P = .002) and Knosp grade of 0 (OR = 0.09, reference Knosp grade 4, P = .03) to be protective against recurrence. Comparison of Knosp grade 0 to 2 vs 3 to 4 showed that lower grades had reduced risk of recurrence (OR = 0.27, P = .04). Other factors such as length of stay, surgeon experience, prior tumor treatment, and Knosp grades 1, 2, or 3 failed to reach levels of statistical significance in multivariable analysis. This multicenter study centers suggests that the strongest predictors of recurrence include tumor size/invasion and age. This insight can help with patient counseling and prognostication. Long-term follow-up is necessary for patients, and early treatment of small tumors may improve outcomes.

Short-term outcomes of minimally invasive techniques in posterior component separation for ventral hernia repair: a systematic review and meta-analysis.

The objective of this study was to perform a systematic review and meta-analysis to summarize various approaches in performing minimally invasive posterior component separation (MIS PCS) and ascertain their safety and short-term outcomes. A systematic literature searches of major databases were conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines to identify studies that provided perioperative characteristics and postoperative outcomes of MIS PCS. Primary outcomes for this study were: surgical site events (SSE), surgical site occurrence requiring procedural intervention (SSOPI), and overall complication rates. A random-effect meta-analysis was conducted which allows computation of 95% CIs using simple approximation and incorporates inverse variance method with logit transformation of proportions. There were 14 studies that enrolled 850 participants that were included. The study identified rate of SSE, SSOPI, and overall rate of complications of all MIS TAR modifications to be 13.4%, 5.7%, and 19%, respectively. Our study provides important information on safety and short-term outcomes of MIS PCS. These data can be used as reference when counseling patients, calculating sample size for prospective trials, setting up targets for prospective audit of hernia centers. Standardization of reporting of preoperative characteristics and postoperative outcomes of patients undergoing MIS PCS and strict audit of the procedure through introduction of prospective national and international registries can facilitate improvement of safety of the MIS complex abdominal wall reconstruction, and help in identifying the safest and most cost-effective modification.

Primary robot-assisted laparoscopic partial nephrectomy for hemorrhage secondary to angiomyolipoma: a retrospective study from a large tertiary hospital in China

With the continuous development of robot-assisted technology, Robot-assisted Laparoscopic Partial Nephrectomy (RALPN) has gradually become an optional method for the treatment of Hemorrhage secondary to angiomyolipoma (HSA). However, there are rare clinical reports of the primary RALPN for HSA. Therefore, this research aims to evaluate the efficacy and safety of primary RALPN for HSA. Fourteen patients(six males and eight females), aged 14–56 years, underwent primary RALPN for HSA and were retrospectively analyzed from 2015 to 2023. The initial blood routine examination revealed decreased hemoglobin in all patients, and Contrast-enhanced computed tomography (CT) indicated retroperitoneal hematoma. After correcting shock and electrolyte imbalance through fluid therapy and medical treatment, all primary RALPN procedures were performed with transabdominal access on the side of the Hemorrhage. After tumor resection and hematoma removal with a monopolar Curved Scissor, the absorbable barbed suture was performed for inner and outer running stitches, respectively. Patient demographic information, perioperative characteristics, and functional outcomes were collected and analyzed. The initial tumor size of fourteen patients ranged from 57 to 145 mm, and the RENAL ranged from 7 to 11. All of the HSA was controlled, and primary RALPN was successful. The operating time it was ranged from 105 to 265 min. Postoperatively, one patient exhibited chylous drainage (Clavien-Dindo II), and another patient developed pleural effusion (Clavien-Dindo III). No postoperative transfusion and Digital Subtraction Angiography (DSA) highly selective embolization of the bleeding vessel was needed. No patients developed urinoma or urinary fistula. Within the follow-up period, the overall complications were manageable. Primary RALPN is a safe and effective procedure for HSA, which may be considered an alternative to selective renal artery embolization.

An Assessment of Adverse Events in Patients with 22q11.2 Deletion Syndrome Undergoing Palatoplasty: An Analysis of the NSQIP Pediatric Database.

The National Surgical Quality Improvement Program (NSQIP) Pediatric database has been used to identify factors related to adverse surgical outcomes in pediatric and craniofacial surgical procedures. Focusing on a historically "higher-risk" population, our aim was to assess the impact of demographics, comorbidities, and 22q11.2 deletion syndrome (22QDS) diagnosis on 30-day postoperative complications in patients undergoing primary palatoplasty. We used the 2012-2020 NSQIP Pediatric database to identify patients ≤3 years with and without 22q11.2 deletion syndrome who underwent primary palatoplasty. Demographics, comorbidities, and perioperative characteristics were compared between those with and without 22QDS. Logistic regression was used to determine if children with 22QDS were more likely to experience a 30-day postoperative complication or readmission. There were 10,745 patients ≤3 years old who underwent primary palatoplasty; 83 (0.8%) of whom had 22QDS and 10,662 (99.8%) did not. Children with 22QDS were older when they underwent primary palatoplasty and more likely to have comorbidities. A total of 513 patients (4.8%) experienced a postoperative complication within 30 days and 255 were readmitted (2.4%). Of the 513, 8 (9.6%) had a 22QDS diagnosis and 505 (4.7%) did not. A diagnosis of 22QDS was not a significant independent risk factor for a complication (adjusted odds ratio (aOR) = 1.13; 95% confidence interval (CI): 0.50-2.54) or readmission (aOR = 1.74; 95% CI: 0.74-4.13) within 30 days. This study found that the diagnosis of 22QDS was not an independent predictor of post-palatoplasty complication risk, and in fact 30-day complications are rare for those patients undergoing cleft palate repair, even among those patients with 22QDS.

Stage-based recipient and donor outcome in twin-to-twin transfusion syndrome treated by fetoscopic laser surgery using Solomon technique.

To evaluate twin survival stratified by Quintero stage in patients with twin-to-twin transfusion syndrome (TTTS) after Solomon laser treatment. This was a single-center study at Johns Hopkins Center for Fetal Therapy, investigating a cohort of consecutive twin pregnancies treated with the Solomon laser technique for TTTS. Preoperative Quintero stage, perioperative characteristics and obstetric factors were investigated in relation to neonatal survival of the recipient and donor twins at discharge. Determinants of twin survival were evaluated using univariate logistic regression and cumulative survival probability analyses. Of 402 pregnancies with TTTS that underwent Solomon laser treatment, 80 (19.9%) were diagnosed with Quintero Stage-I TTTS, 126 (31.3%) with Stage II, 169 (42.0%) with Stage III and 27 (6.7%) with Stage IV. Post-laser twin anemia polycythemia sequence or recurrent TTTS occurred in 19 (4.7%) patients and 11 (2.7%) required repeat laser surgery. Preterm prelabor rupture of membranes occurred in 150 (37.3%) patients and median gestational age at delivery was 32 + 1 weeks. In 303 (75.4%) patients, both twins were alive at discharge; 67/80 (83.8%) were Stage I, 101/126 (80.2%) were Stage II, 113/169 (66.9%) were Stage III and 22/27 (81.5%) were Stage IV (P = 0.062). Donor twin survival was lower than that of recipients in cases with Stage-III TTTS (118/169 (69.8%) vs 145/169 (85.8%) (χ2 = 26.076, P < 0.0001)). Higher intertwin size discordance and absent or reversed umbilical artery (UA) end-diastolic velocity (EDV) were associated with donor demise (Nagelkerke R2, 0.38; P < 0.001). Overall, spontaneous post-laser donor demise occurred in 53 (39.6%) patients, accounting for the majority of all losses. Cumulative donor survival decreased from 92% to 65% when intertwin size discordance was >30% and to 48% when UA-EDV was absent or reversed (P < 0.001). The Solomon laser technique achieves TTTS resolution and double twin survival in a high proportion of cases. Recipient and donor survival is comparable unless there is significant intertwin size discordance and placental dysfunction. This degree of unequal placental sharing, typically found in Stage-III TTTS, is the primary factor preventing double survival due to a higher rate of donor demise. © 2024 International Society of Ultrasound in Obstetrics and Gynecology.

The impact of obesity on gastroesophageal reflux disease recurrence following re-operative anti-reflux surgery.

Obese patients represent a large proportion of patients experiencing recurrent reflux and re-operations after initial anti-reflux surgery. However, there is a limited data describing the impact of obesity on GERD recurrence following re-operative procedures. A review of patients who underwent re-operative anti-reflux surgery (Re-ARS) between 2012 and 2023. Peri-operative characteristics and post-operative Gastroesophageal Reflux Disease-Health Related Quality of Life (GERD-HRQL) scores were compared across the three BMI categories: (BMI < 25kg/m2, 25 ≤ BMI > 30kg/m2, and BMI ≥ 30kg/m2) over 12 IQR (9-14.9) months follow-up. Impedance planimetry measurements were included when it was utilized intraoperatively. Of 718 patients who underwent robotic ARS, 84 patients (11.6%) underwent Re-ARS, of which 29.7% had a BMI < 25kg/m2, 35.7% were ≤ 25 BMI < 30kg/m2, and 34.5% had a BMI ≥ 30kg/m2. The lower esophageal sphincter distensibility decreased similarly between groups with no differences in post-induction [3.2 ± 2 vs 4.5 ± 3.1 vs 3.9 ± 2.5 mm2/mmHg, p = 0.44] or post-fundoplication values [1 ± 0.6 vs 1.3 ± 0.7 vs 1.2 ± 0.6 mm2/mmHg, p = 0.46]. There was a significant improvement in GERD-HRQL scores postoperatively compared to preoperative levels across the three BMI classes (BMI < 25kg/m2: pre 17 IQR (12-22), post 7.5 (1.5-15), p = 0.04 vs ≤ 25 BMI < 30kg/m2: pre 26 IQR (10-34), post 8 IQR (0-17), p < 0.01 vs BMI ≥ 30kg/m2: pre 44 IQR (26-51), post 5 IQR (3.5-14.5), p < 0.001) during 12 IQR (9-14.9) months follow-up. The rates of hiatal hernia recurrence on barium swallow [5.2 vs 15.7 vs 13.7%, p = 0.32] during 7 IQR (5.2-9.2) months follow-up, and endoscopy [13.3 vs 16.6 vs 7.1%, p = 0.74] during 11.8 (IQR 5.6-17.1) months follow-up period were also similar between groups. GERD-HRQL scores in obese patients are expected to improve similarly compared to non-obese patients. Indicating that Re-ARS may be appropriate for patients across a range of BMIs.

Tranexamic Acid in Patients Undergoing Liver Resection

Tranexamic acid reduces bleeding and blood transfusion in many types of surgery, but its effect in patients undergoing liver resection for a cancer-related indication remains unclear. To determine whether tranexamic acid reduces red blood cell transfusion within 7 days of liver resection. Multicenter randomized clinical trial of tranexamic acid vs placebo conducted from December 1, 2014, to November 8, 2022, at 10 hepatopancreaticobiliary sites in Canada and 1 site in the United States, with 90-day follow-up. Participants, clinicians, and data collectors were blinded to allocation. A volunteer sample of 1384 patients undergoing liver resection for a cancer-related indication met eligibility criteria and consented to randomization. Tranexamic acid (1-g bolus followed by 1-g infusion over 8 hours; n = 619) or matching placebo (n = 626) beginning at induction of anesthesia. The primary outcome was receipt of red blood cell transfusion within 7 days of surgery. The primary analysis included 1245 participants (mean age, 63.2 years; 39.8% female; 56.1% with a diagnosis of colorectal liver metastases). Perioperative characteristics were similar between groups. Red blood cell transfusion occurred in 16.3% of participants (n = 101) in the tranexamic acid group and 14.5% (n = 91) in the placebo group (odds ratio, 1.15 [95% CI, 0.84-1.56]; P = .38; absolute difference, 2% [95% CI, -2% to 6%]). Measured intraoperative blood loss (tranexamic acid, 817.3 mL; placebo, 836.7 mL; P = .75) and total estimated blood loss over 7 days (tranexamic acid, 1504.0 mL; placebo, 1551.2 mL; P = .38) were similar between groups. Participants receiving tranexamic acid experienced significantly more complications compared with placebo (odds ratio, 1.28 [95% CI, 1.02-1.60]; P = .03), with no significant difference in venous thromboembolism (odds ratio, 1.68 [95% CI, 0.95-3.07]; P = .08). Among patients undergoing liver resection for a cancer-related indication, tranexamic acid did not reduce bleeding or blood transfusion but increased perioperative complications.

Adolescent pilonidal disease laser treatment (a-PiLaT): a pilot study

BackgroundPilonidal disease (PD) is an acquired condition related to hair-induced mechanical forces on the skin surface of the intergluteal cleft, with subsequent abscess formation with or without a concomitant draining sinus (pit). While surgical management currently is the mainstay of treatment, pilonidal disease laser treatment (PiLaT) has recently been recognized as a promising treatment option for non-inflammatory diseases. Nonetheless, there is a paucity of available data on adolescent pilonidal disease laser treatment (a-PiLaT).MethodsWe describe our preliminary experience with PiLaT performed in adolescents aged 10–17 years at our tertiary paediatric surgical hospital from 2019 to 2023. Data on perioperative characteristics and clinical outcomes at follow-up were retrospectively analysed.ResultsA total of 17 consecutive patients (n = 12 female, 71%) underwent a-PiLaT. At the time of treatment, the patients’ mean age and body mass index were 13.6 ± 1.6 years and 25.3 ± 5.6 kg m−2, respectively. The mean operative time was 21.5 ± 10.4 min, whereas the mean follow-up period was 24.5 ± 16.8 months, with a complication rate of 24% (n = 4) and recurrence rate of 18% (n = 3). With respect to postsurgical scar assessment, the mean Patient and Observer Scar Assessment Scale scores (score range 6–60, with higher scores indicating worse outcome) were 14.2 ± 6.5 (patients’ evaluation) and 11.4 ± 4.7 (observers’ evaluation).ConclusionThe a-PiLaT represents a novel approach for managing PD in adolescents. Our preliminary data on the outcomes of a small series of patients with pilonidal sinuses after a-PiLaT indicated complication and recurrence rates comparable to those reported in the literature for adults. This new minimally invasive technique has great potential and is therefore worthy of further research on a larger population.

Impact of preoperative back pain severity on PROMIS outcomes following minimally invasive lumbar decompression.

To evaluate the effect of baseline back pain severity on PROMIS mental health outcomes following minimally invasive lumbar decompression (LD). Patients undergoing elective, primary, single-level LD were retrospectively reviewed from a prospective single spine surgeon registry. Perioperative characteristics, demographics, and the following patient-reported outcomes (PROs) were extracted: Oswestry Disability Index (ODI)/Patient-Health Questionnaire-9 /PROMIS-Physical Function/Anxiety/Pain Interference/Sleep Disturbance (PROMIS-PF/A/PI/SD). Two cohorts were created: preoperative VAS-B < 7 and VAS-B ≥ 7. Change in PROs (ΔPROs) from baseline to six weeks/final follow-up were determined. Average patient follow-up was 13.4 ± 8.8months. Minimal clinically important difference (MCID) achievement rates were calculated and compared through multivariable logistic regression. Postoperative scores and ΔPROs, were compared with multivariable linear regression while all other data was compared between groups with inferential statistics. Altogether, 347 patients were included, with 190 in the VAS-B < 7 group. VAS-B ≥ 7 reported worse outcomes preoperatively (p ≤ 0.013, all). At six weeks, VAS-B ≥ 7 reported worse VAS-B (p = 0.017), with no other significant differences. At final follow-up, patients with worse VAS-B reported worse ODI (p = 0.040) and VAS-B while all other PROs were similar (p ≥ 0.078, all). VAS-B ≥ 7 experienced greater 6-week improvements in VAS-B/ODI/PROMIS-PI/PROMIS-SD (p ≤ 0.009, all), greater VAS-B/ODI/PROMIS-SD improvement by final follow-up (p ≤ 0.009, all) and greater MCID achievement in ODI/VAS-B (p ≤ 0.027). Patients with worse baseline back pain report inferior baseline scores that converge with those with milder preoperative back pain by 6weeks after LD and reported greater 6-week improvements in disability, pain interference, and sleep disturbance by 6weeks, and greater improvements in disability and sleep disturbance by final follow-up.

Effect of pericapsular nerve group block on perioperative analgesia characteristics for hip fracture operations

Aims: Pericapsular nerve group (PENG) block is a new regional analgesia technique that has recently been used for perioperative analgesia for hip fracture operations. The purpose of this research was to examine the perioperative analgesic characteristics of PENG block in patients who were going to undergo spinal anesthesia for a hip fracture procedure. Methods: The study was conducted as a prospective randomized controlled study between February 2021 and May 2021 after ethics committee approval. Patients with consent were included in the study. The patients were randomly divided into two groups (Group-I and Group-II). Patients in Group I underwent a PENG block with a 0.25% concentration of 20 cc bupivacaine in the preoperative waiting room 30 minutes before the operation. Afterward, spinal anesthesia was applied in the operating room. The patients in Group II received only spinal anesthesia. Preoperative visual analog scale (VAS) scores were recorded for both groups in the preoperative period. ECG, arterial blood pressure, pulse, and oxygen saturation measurements were performed in all patients preoperatively, intraoperatively, and postoperatively. Pulse, arterial blood pressure, oxygen saturation measurements, and VAS scores were recorded in the lateral decubitus position before and at the 5th minute after spinal anesthesia. In addition, the comfort of the anesthetist who will administer the spinal anesthesia during the application was questioned (0: poor, 1: moderate, 2: good, 3: very good). All patients 5 min after spinal anesthesia It remained in the lateral position for the duration. VAS scores were recorded during the postoperative phase at the 0th, 2nd, 8th, 16th, and 24th hours, along with the time of the first analgesic administration. The total amount of tramadol and paracetamol taken during the first 24 hours following surgery was noted. Results: Patients; gender, age, body weight, height, BMI, and ASA values were statistically similar (p &gt; 0.05). In comparisons between the groups; During position, postoperative 2nd, 8th, 16th, 24th hours, and their sum, VAS values were found to be statistically lower in Group-I (p &lt; 0.05). While it was found that the first analgesic administration time was statistically longer in Group-I patients (p &lt; 0.001), the amounts of paracetamol and tramadol consumed in the first 24 hours were found to be statistically lower (p &lt; 0.001). In addition, the comfort of the anesthetist during spinal anesthesia was found to be better in Group-I (p: 0.014). Conclusion: PENG block can be used effectively as a part of perioperative multimodal analgesia in hip fracture surgery. PENG can reduce the pain levels of patients with hip fractures as well as reduce the need for additional analgesia. It also increases the comfort of the anesthetist who will administer regional anesthesia.
