RESUMEN
PURPOSE OF REVIEW: The aim of this review is to present the current state of the field, highlight recent developments, and describe the clinical outcomes of endoscopic therapies for bariatric surgery complications. RECENT FINDINGS: The field of interventional endoscopy now presents a range of minimally invasive procedures for addressing postbariatric complications. Lumen-opposing metal stents have emerged as a reliable solution for managing gastrojejunal strictures following Roux-en-Y gastric bypass, whether with or without associated leaks. Additionally, they serve as a conduit for performing endoscopic retrograde cholangiopancreatography (ERCP) post-RYGB via EUS-directed ERCP (EDGE). Gastric peroral endoscopic myotomy, originally designed for gastroparesis, has demonstrated effectiveness in treating postgastric sleeve stenosis, particularly the challenging helical stenosis cases. Furthermore, innovative endoscopic antireflux techniques are showing encouraging outcomes in addressing gastroesophageal reflux disease (GERD) following sleeve gastrectomy. Additionally, several modifications have been proposed to enhance the efficacy of transoral outlet reduction (TORe), originally developed to treat weight regain due to gastrojejunal anastomotic issues post-RYGB. SUMMARY: Endoscopic management of bariatric surgery complications is continuously evolving. The development of new techniques and devices allows endoscopists to provide novel, minimally invasive alternatives that were not possible in the near past. Many techniques, however, are limited to expert centers because they are technically demanding, and specialized training in bariatric endoscopy is still required.
RESUMEN
BACKGROUND: One anastomosis gastric bypass (OAGB) is described as a simpler, potentially safe, and effective bariatric-metabolic procedure that has been recently endorsed by the American Society of Metabolic and Bariatric Surgery. OBJECTIVES: First, we aim to compare the 30-day outcomes between OAGB and other bypass procedures: Roux-en-Y gastric bypass (RYGB) and single anastomosis duodenoileal bypass with sleeve gastrectomy (SADI-S). Second, identify the odds between postoperative complications and each surgical procedure. METHODS: Patients who underwent primary OAGB, RYGB, and SADI-S were identified using the MBSAQIP database of 2020 and 2021. An analysis of patient demographics and 30-day outcomes were compared between these three bypass procedures. In addition, a multilogistic regression for overall complications, blood transfusions, unplanned ICU admissions, readmission, reoperation, and anastomotic leak stratified by surgical procedure was performed. RESULTS: 1607 primary OAGBs were reported between 2020 and 2021. In terms of patient demographics, patients who underwent RYGB and SADI-S showed a higher incidence of comorbidities. On the other hand, OAGB had shorter length of stay (1.39 ± 1.10 days vs 1.62 ± 1.42 days and 1.90 ± 2.04 days) and operative times (98.79 ± 52.76 min vs 125.91 ± 57.76 min and 139.85 ± 59.20 min) than RYGB and SADI-S. Similarly, OAGB showed lower rates of overall complications (1.9% vs 4.5% and 6.4%), blood transfusions (0.4% vs 1.1% and 1.8%), unplanned ICU admission (0.3% vs 0.8% and 1.4%), readmission (2.4% vs 4.9% and 5.0%), and reoperation (1.2% vs 1.9% and 3.1%). A multilogistic regression analysis was performed, RYGB and SADI-S demonstrated higher odds of 30-day complications. CONCLUSION: The incidence of primary OAGB has increased since its approval by ASMBS, from 0.05% reported between 2015 and 2019 to 0.78% between 2020 and 2021. OAGB had better 30-day outcomes and shorter operative times than RYGB and SADI-S and therefore, could be considered a viable alternative.

BACKGROUND: The Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) Masters Program designated bariatric surgery as a clinical pathway. Among the tiers of the Masters Program, revisional bariatric surgery is the highest tier of "mastery" within the pathway. This article presents the top 10 seminal studies representing the current landscape of revisional bariatrics. METHODS: The literature was systematically searched and seminal articles designated by consensus agreement of the SAGES Metabolic and Bariatric Surgery committee using multiple criteria, including impact on the field, citation frequency, and expert opinion. Articles were reviewed by committee members and presented in summarized fashion. RESULTS: The top 10 papers are presented in grouped thematic categories covering the early evolution of revisional bariatrics, changing criteria for reoperative bariatric surgery, divergence of revision versus conversion bariatric surgery, and recent technologic innovations in revisional bariatric surgery. Each summary is presented with expert appraisal and commentary. CONCLUSION: These seminal papers represent a snapshot of the dynamic field of revisional bariatric surgery and emphasize the need to not only remain current with contemporary trends but also keep a patient-oriented perspective on patient and intervention selection for optimal success.

BACKGROUND: We compared surgeons' workload, physical discomfort, and neuromusculoskeletal disorders (NMSDs) across four surgical modalities: endoscopic, laparoscopic, open, and robot-assisted (da Vinci Surgical Systems). METHODS: An electronic survey was sent to the surgeons across an academic hospital system. The survey consisted of 47 questions including: (I) Demographics and anthropometrics; (II) The percentage of the procedural time that the surgeon spent on performing each surgical modality; (III) Physical and mental demand and physical discomfort; (IV) Neuromusculoskeletal symptoms including body part pain and NMSDs. RESULTS: Seventy-nine out of 245 surgeons completed the survey (32.2%) and 65 surgeons (82.2%) had a dominant surgical modality: 10 endoscopic, 15 laparoscopic, 26 open, and 14 robotic surgeons. Physical demand was the highest for open surgery and the lowest for endoscopic and robotic surgeries, (all p < 0.05). Open and robotic surgeries required the highest levels of mental workload followed by laparoscopic and endoscopic surgeries, respectively (all p < 0.05 except for the difference between robotic and laparoscopic that was not significant). Body part discomfort or pain (immediately after surgery) were lower in the shoulder for robotic surgeons compared to laparoscopic and open surgeons and in left fingers for robotic surgeons compared to endoscopic surgeons (all p < 0.05). The prevalence of NMSD was significantly lower in robotic surgeons (7%) compared to the other surgical modalities (between 60 and 67%) (all p < 0.05). CONCLUSIONS: The distribution of NMSDs, workload, and physical discomfort varied significantly based on preferred surgical approach. Although robotic surgeons had fewer overall complaints, improvement in ergonomics of surgery are still warranted.

INTRODUCTION: Different techniques have been proposed for reoperation after failed anti-reflux surgery. However, there is no consensus on which should be preferred. We aim to report and compare the outcomes of different revisional techniques for failed anti-reflux surgery. METHODS: We performed a retrospective analysis of patients who underwent redo fundoplication (RF) or Roux-en-Y gastric bypass (RYGB) conversion after a failed fundoplication at our institution between 2016 and 2021. The primary outcome was long-term presence of reflux or dysphagia following revisional surgery. Secondary outcomes included 30-day perioperative complications as well as long-term use of anti-reflux medication and radiographic recurrence of hiatal hernia (HH). RESULTS: A total of 165 (median age 63 years, 73.9% female) patients were included. RF was performed in 120 (73 Toupet and 47 Nissen), RYGB in 38, and 7 patients had fundoplication takedown alone. The RYGB group had a significantly higher BMI, and more prior revisional surgeries compared to the other groups. Median operative time and length of stay were longer for RYGB. Twenty (12.1%) patients experienced postoperative complications, with the highest incidence in the RYGB group. Reflux and dysphagia improved significantly for the whole cohort, with the greatest improvement noted with reflux in the RYGB group (89.5% with preoperative reflux vs. 10.5% with postoperative reflux, p = < .001). On multivariable regression we found that prior re-operative surgery was associated with persistent reflux and dysphagia, whereas RYGB conversion was protective against reflux. CONCLUSION: Conversion to RYGB may offer superior resolution of reflux than RF, especially for obese patients.

BACKGROUND: The respiratory coefficient (RQ), as determined by indirect calorimetry (IC), classifies diet as being carbohydrate rich (RQ = 0.7-0.8), fat rich (RQ = 0.9-1.0), or overfeeding (RQ > 1). We hypothesized that preoperative RQ may be associated with weight-loss outcomes after bariatric surgery. METHODS: From 2016 to 2018, 137 obese patients were enrolled in a Bariatric Registry and underwent dietary and behavioral counseling, followed by preoperative IC. Resting energy expenditure (REE) and RQ of all patients was measured. Patients were classified as over-feeders (OF; 42, 31%) with RQ > 1 or non-over-feeders (NOF; 95, 69%) with RQ < 1. At baseline, there was no difference between groups in gender [female: 105 (76.6%), male: 32 (23.4%)], body mass index (BMI; OF: 46.8 ± 7.8 vs. NOF: 44.8 ± 7.4 kg/m2, p = 0.40), or baseline REE (OF: 1897 ± 622 vs. NOF: 1874 ± 579, p = 0.74), although OF were younger [mean age (OF: 47.1 ± 13.0 years vs. NOF: 43.1 ± 13.4; p = 0.009). At 6-month follow-up 94 patients [53.28%; OF: 35 (83%) vs. NOF: 59 (62%), p = 0.016] were seen and 48 [35.03%; OF: 23 (55%) vs. NOF: 25 (59%), p = 0.001] at 12-month follow-up. On preoperative psychological assessment, OF had a significantly higher rate of childhood neglect (OF: 28 (47.46%) vs. NOF: 40 (28.99%); p = 0.01). RESULTS: At 1 year postoperatively, the OF had a significantly higher BMI (OF: 34.3 ± 6.5 vs. NOF: 29.3 ± 5.1 kg/m2, p = 0.009). Differences in weight were not significant at 6-month (OF: 36.0 ± 6.5 vs. NOF: 33.5 ± 5.9 kg/m2, p = 0.07). There was no difference between type of operation and RQ group (RYGB; OF: 55 (75%) vs. NOF: 18 (25%) and SG; OF: 40 (62%) vs. NOF: 24 (38%), p = 0.14), nor in BMI loss after operation. CONCLUSION: Evidence of overfeeding in the preoperative period prior to bariatric surgery is associated with higher resultant BMI at 1 year. Calculation of the RQ with IC has prognostic significance in bariatric surgery, and calculation of REE based on assumed normal RQ potentiates error. It is unclear if overfeeding is purely behavioral or secondary to potentially reversible metabolic etiology.

BACKGROUND: Despite the effectiveness of antireflux fundoplication for typical gastroesophageal reflux disease, outcomes regarding surgical therapy for patients with gastroesophageal reflux disease-related chronic cough are currently unclear. The purpose of this study was to evaluate whether antireflux surgery for patients with chronic cough is effective, and to assess the correlation between indexes, such as symptom index and symptom association probability, and response to surgery. METHODS: We performed a retrospective review of a prospectively collected database from a 3-site institution from 2013 to 2017. Of 1149 patients who underwent antireflux surgery, 41 presented with chronic cough as a main symptom related to gastroesophageal reflux disease. Preoperatively, patients underwent a symptom assessment, esophagogastroduodenoscopy, esophageal 24-h pH monitoring, and manometry. Patients were followed up at 6 weeks and 12 months post-surgery. RESULTS: Thirty-three (80.5%) patients underwent Nissen fundoplication, while 8 (19.5%) underwent Toupet fundoplication. Isolated chronic cough was present in 8 (19.5%) patients, and median (range) DeMeester score was 28.9 (0.3-96.7). After 12-month follow-up, chronic cough was absent in 28 (68.3%) patients (P = .02). Typical reflux symptoms responded well to surgery, but response was not optimal. Postoperative dysphagia and atypical reflux symptoms were slightly worse on long-term follow-up; however, differences were not significant (P ≥ .2). When examining how the different symptom indexes correlated with complete, partial, or no response in patients with gastroesophageal reflux disease-related cough, there was no notable agreement on predicted response to surgery. CONCLUSIONS: Antireflux surgery, although less predictable, is effective for the treatment of gastroesophageal reflux disease-related chronic cough.

BACKGROUND: Outcomes are not well studied in patients undergoing remediation for multi-fundoplication failure, that is, two or more prior failed fundoplications. Re-operation must balance reflux control and restoration of the ability to eat with the challenge of reconstructing a distorted hiatus and GE junction. The purpose of this study is to present our experience with surgical remediation for multi-fundoplication failure. METHODS: Medical records were retrospectively reviewed of 91 patients who underwent third time or more esophagogastric operation for fundoplication failure at a single institution from 2007 to 2016. Dysphagia was present in 56% and heartburn in 51%. Median number of prior operations was 2 with range up to 6. Anatomic failure consisted of slipped wrap in 26 cases, wrap herniation in 23, hiatal stenosis in 24, hiatal mesh complication in 8, and wrap dehiscence in 10. Operative approaches generally followed an institutional algorithm and consisted of hiatal hernia repair with: re-do fundoplication in 55%, takedown of fundoplication alone in 24%, Roux-en-Y gastrojejunostomy in 14%, and GE junction resection in 7%. Laparoscopic approach was successful in 81%. RESULTS: Mean duration of operations was 217 min and median length of stay was 3 days. The complication rate was 13%, with 7% undergoing unplanned early re-operation. Patients were followed for mean 11 months, and recurrent hiatal hernia was detected in 13%. Late re-operation was performed in 6% for recurrent hiatal hernia. Recurrent reflux symptomatology resolved in 93%. Dysphagia resolved in 84%. There were no significant differences in outcomes with regard to number of prior operations, operative approach, BMI, or age. CONCLUSIONS: There is no single best approach to remediation in the multi-fundoplication failure patient. Re-do fundoplication is appropriate in over half of patients. Reoperation for multi-fundoplication failure can be performed via minimally invasive approach with excellent remediation of symptoms, low morbidity, and low recurrence rates.

BACKGROUND: Laparoscopic adjustable gastric banding (LAGB) was a popular procedure in the USA and Europe in the past decade. However, its use has currently declined. Band erosion (BE) is a rare complication after LAGB with a reported incidence rate of 1.46 %. Controversies exist regarding the management, approach and timing for the band removal. The aim of this study is to describe the rate, clinical presentation and perioperative outcomes of BEs at our institution and provide overall recommendations regarding the diagnosis and management of BE. MATERIALS AND METHODS: This study is a single-center, retrospective review of a prospectively maintained database. Data were collected from all consecutive patients who underwent a LAGB and band revisional surgeries at the University of Illinois Hospital and Health Sciences System from December 2008 to September 2015. We identified patients who underwent gastric band removal due to a BE and analyzed their outcomes. RESULTS: A total of 576 LAGBs were performed at our institution. Nine patients underwent surgery for BE at our hospital. The average time between the primary surgery and the removal of the band was 68.5 (42.9) months. Abdominal pain, nausea and/or vomiting were the most frequently mentioned symptoms. In all patients, a minimally invasive approach was used to remove the band. The mean length of hospitalization was 2.6 (1.1) days. The only complication was a pneumonia (n = 1). CONCLUSIONS: BE is one of the most severe complications of LAGB. The minimally invasive approach provided us with the opportunity to repair the fistula, and it was associated with a prompt recovery with very little morbidity. In general, it is recommended that the band be removed at the time of the diagnosis of the BE. Endoscopic band removal can be utilized with patients who have a more advanced BE and migration into the gastric lumen.

BACKGROUND: Abdominal lipectomy after bariatric surgery is recommended because of residual excess skin resulting in difficulty with maintaining hygiene, recurrent infections, and functional impairment, interfering with daily activities. There is a dearth of literature examining weight loss outcomes in patients undergoing abdominal lipectomy post sleeve gastrectomy (SG). The purpose of this study was to examine whether post-SG patients who received abdominal lipectomy achieved greater percent excess weight loss (%EWL) than post-SG patients who did not receive abdominal lipectomy. METHODS: Retrospective study of patients who underwent minimally invasive SG at the University of Illinois Hospital and Health Sciences System from March 2008 to June 2015 was conducted. The cohort was divided into 2 groups: patients who underwent abdominal lipectomy after SG (PS-SG) and patients who underwent SG alone (SG). Demographics, comorbidities, and %EWL were examined. RESULTS: Twenty-nine patients were included in the PS-SG group versus 287 patients in the SG group. Significant differences were found in %EWL at 24 (P < 0.0001), 36 (P < 0.005), and more than 36 months (P < 0.005) follow-up between groups, with a greater %EWL in patients in the PS-SG group versus the SG group. CONCLUSIONS: This preliminary study revealed that patients in the PS-SG group achieved greater %EWL than patients with SG alone. Although larger studies are needed, this study supports using abdominal lipectomy as an adjunctive procedure to assist with long-term weight loss as part of the overall treatment of bariatric surgery patients.

INTRODUCTION: Among morbidly obese adult patients (BMI >40 kg/m(2)), those who are super-super obese (BMI >60 kg/m(2)) present particular challenges for bariatric surgeons. Surgical management of super-super obese (SSO) patients has been associated with higher morbidity and mortality and increased surgical risk. The optimal surgical management of these patients is controversial. The aim of this study was to compare perioperative outcomes, percent excess weight loss (%EWL), and percent weight loss (%WL) in super-super obese patients who underwent either SG or RYGB. MATERIALS AND METHODS: This study was a nonrandomized, controlled, retrospective review of 89 SSO patients who underwent SG or RYGB at the University of Illinois Hospital and Health Sciences System from January 2008 to June 2014. Patient demographics, pre-surgical comorbidities, perioperative parameters, post-operative complications (leak, conversion to open surgery, and 30-day mortality), and post-operative outcome months were examined. RESULTS: Seventy-seven patients underwent SG (nine robotic sleeve and 68 laparoscopic sleeve gastrectomy), and 12 underwent RYGB. The mean pre-operative BMI was 63.4 kg/m(2) (SD = 3.7 kg/m(2)). The mean operative time was 88.4 min (SD = 31.7) for the SG patients and 219.2 min (SD = 80.2) for the RYGB patients. There were no significant differences in complications or length of hospitalization between the groups. There were significant differences in %EWL and %WL at 12- and 24-month follow-up between groups (p's < 0.05). CONCLUSIONS: Based on the results from this sample of patients, SG and RYGB appear to be viable procedures for the surgical management of super-super obese patients. RYGB, however, provides a significantly higher %EWL and %WL at 12 and 24 months compared to SG, which in turn, yields acceptable but lower %EWL and %WL.

INTRODUCTION: Laparoscopic gastric band is an appealing bariatric operation due to its simplicity and good short-term outcomes; however, it is associated with complications (slippage, erosion, prolapse) and failure in reaching target weight loss. This study describes our experience with failed gastric bands that required a revisional procedure. MATERIALS AND METHODS: This single-center retrospective analysis includes all consecutive patients who underwent a gastric band removal and revisional surgery in our hospital from January 2008 to June 2014. A total of 81 patients were identified and divided in three groups: Group one included patients who just had the gastric band removed (43), group two consisted of patients who underwent a conversion to sleeve gastrectomy (SG) (26), and group three included patients who required a conversion to Roux-en Y gastric bypass (RYGB) (12). Patient demographics, date of gastric band placement, indications for revision, postoperative morbidity and mortality, operating time, blood loss, length of stay, and % excess weight loss (%EWL) were recorded. Perioperative and clinical outcomes were compared between conversions to SG and RYGB. RESULTS: In group two (n = 26), 21 conversions to SG were performed in concurrence with the band removal as a one-stage operation, while five procedures were performed in two-stages. There were no complications and no case was converted to open. Patients who underwent a one-stage procedure had a longer operative time, although it did not reach statistical significance. In group three, 12 patients underwent a conversion to RYGB as a revisional operation; 11 were performed as a one-stage procedure and only one patient underwent a two-stage procedure. CONCLUSIONS: SG and RYGB are safe options to revise a failed gastric band. Both groups who received either a SG or RYGB had a low complication rate and acceptable %EWL with no statistical difference between the two.

BACKGROUND/AIM: Laparoscopic cholecystectomy is currently the gold standard treatment for gallstone disease. Bile duct injury is a rare and severe complication of this procedure, with a reported incidence of 0.4% to 0.8% and is mostly a result of misperception and misinterpretation of the biliary anatomy. Robotic cholecystectomy has proven to be a safe and feasible approach. One of the latest innovations in minimally invasive technology is fluorescent imaging using indocyanine green (ICG). The aim of this study is to evaluate the efficacy of ICG and the Da Vinci Fluorescence Imaging Vision System in real-time visualization of the biliary anatomy. METHODS: A total of 184 robotic cholecystectomies with ICG fluorescence cholangiography were performed between July 2011 and February 2013. All patients received a dose of 2.5 mg of ICG 45 minutes prior to the beginning of the surgical procedure. The procedures were multiport or single port depending on the case. RESULTS: No conversions to open or laparoscopic surgery occurred in this series. The overall postoperative complication rate was 3.2%. No biliary injuries occurred. ICG fluorescence allowed visualization of at least 1 biliary structure in 99% of cases. The cystic duct, the common bile duct, and the common hepatic duct were successfully visualized with ICG in 97.8%, 96.1%, and 94% of cases, respectively. CONCLUSIONS: ICG fluorescent cholangiography during robotic cholecystectomy is a safe and effective procedure that helps real-time visualization of the biliary tree anatomy.

Background: Partial adrenalectomy (PA) is increasingly used to treat benign tumors to lower the probability of adrenal insufficiency and reduce need for lifetime hormone replacement therapy. Currently, two major concerns are increased bleeding and non-functioning adrenal remnants. This paper examines these concerns and compares surgical approaches with novel findings. Methods: Between 1993 and 2023, 72 patients underwent PA for primary adrenal disorders. Demographic, clinicopathologic and outcome data were analyzed for summary statistics, confidence intervals, and heteroscedastic t-test statistics. Results: The patients were 17-76 years-old and were 59.7 % female. The PA was on the left 54.2 % and bilaterally 4.2 %. The indications were adrenal adenoma, pheochromocytoma, cyst, hyperplasia, and other. The mean tumor diameter was 2.7 cm (range 0.7-10 cm). 23 were performed open, 43 laparoscopically, and 6 with an intended robotic approach. Median follow-up was 9.3 years.Robotic had the shortest length of stay (LOS) (p-value 0.01), then laparoscopic (p-value 0.00004), then open. The estimated blood loss (EBL) ranged from 5 to 500 mL (median 50 mL). The median LOS was two days.Intra-operative complication rate was 1.4 % and readmission within 30 days occurred in 2.8 %. Out of 72 patients, 6.8 % needed hormone replacement; of the 14 patients with contralateral adrenalectomy, 28.6 % needed replacement. Conclusion: PA appears to be safe with both laparoscopic and robotic-assisted techniques with superior perioperative outcomes. The functional results of PA prevent most patients from requiring ongoing steroid replacement treatment and recurrence rates were low. PA should be advised for more frequent use as the preferred treatment method of choice. Key message: Partial adrenalectomies' perioperative and long-term outcomes over a median 9.3 year follow-up emphasized its safety and efficacy with 95 % CI of (2.7 cm, 3.6 cm) for masses with adrenal sufficiency post-resection. Additionally, as healthcare institutions decide whether to invest in surgical robots, robotic approach's outperformance of laparoscopic and open on LOS may be counterbalanced by laparoscopic's strong performance in low EBL.
RESUMEN
BACKGROUND: Venous thromboembolism (VTE) is rare after bariatric surgery but is the most common cause of mortality. The use of VTE risk-stratification tools and compliance with practice guidelines remain unclear. OBJECTIVES: Our objectives were to determine the utilization of risk-stratified VTE prophylaxis and its impact on VTE and bleeding outcomes. SETTING: Academic hospital system. METHODS: Roux-en-Y gastric bypass and sleeve gastrectomy (2016-2021) were identified from our electronic health records. Caprini score and VTE prophylaxis regimen were retrospectively determined. VTE prophylaxis consistent with Caprini guidelines was considered appropriate. Outcomes were compared between VTE prophylaxis cohorts. Variables were compared by Kruskal-Wallis test, Pearson χ2 test, and regression models. A P value of <.05 was considered significant. RESULTS: A total of 1849 bariatric cases were analyzed, including 64% Roux-en-Y gastric bypass and 36% sleeve gastrectomy cases. Of these, 70% and 3.7% received appropriate risk-stratified VTE prophylaxis during hospitalization and at discharge. The mean Caprini score was higher in those without appropriate prophylaxis (8.45 versus 8.04; P = .0004). Inpatient and 30- and 90-day VTE rates were .22%, .47%, and .64%. All discharge VTE events occurred in those not receiving appropriate Caprini risk-stratified VTE prophylaxis. Inpatient and 30- and 90-day bleeding complications were .22%, .23%, and .35%. The likelihood of receiving appropriate prophylaxis varied by hospital site, and receiving appropriate prophylaxis was not associated with increased bleeding risk. CONCLUSION: Caprini guideline-indicated VTE prophylaxis can be safely used in bariatric surgery patients and may reduce preventable VTE complications without increasing bleeding risk.

RESUMEN
PURPOSE: Marginal ulcer (MU) is a known complication after Roux-en-Y gastric bypass (RYGB) that carries significant morbidity. First, we aimed to determine the trends and the rates of readmission, reintervention, and reoperation of 30-day MU. Second, we aim to determine the predictive factors associated with this complication. MATERIALS AND METHODS: Patients who had 30-day marginal ulcer (MU) after LRYGB were identified using the 2015-2021 MBSAQIP database. Those who had a 30-day complication other than MU were excluded. Bivariate and logistic regression analyses were performed. RESULTS: Among 213,104 patients undergoing laparoscopic RYGB, 638 (0.3%) showed 30-day MU. This group of patients required endoscopic interventions, readmissions, and reoperations at rates of 88%, 72%, and 9%, respectively. Predictive factors for 30-day MU after RYGB were renal insufficiency, history of DVT, previous cardiac stent, African American race, chronic steroid use, COPD, therapeutic anticoagulation, anastomotic leak test, GERD, and operative time > 120 min. Additionally, patients who had 30-day MU showed significantly higher rates of overall complications such as pulmonary, cardiac and renal complications, unplanned ICU admission, blood transfusions, venous thromboembolism (VTE), and non-home discharge (p < 0.05). The MU group showed similar rates of 30-day mortality as those without this complication (0.2% vs 0.1%, p = 0.587). CONCLUSIONS: The incidence of 30-day MU following RYGB was 0.3%. Patients with MU required endoscopic interventions, readmissions, and reoperations at rates of 88%, 72%, and 9%, respectively. Some preoperative and intraoperative factors contributed to an increased risk of 30-day MU.

Introduction: Obesity is associated with numerous chronic conditions and an increased risk for surgical complications. Laparoscopic and robotic adrenalectomy have proven effective in the resection of adrenal tumors. This study analyzes the outcomes of severely obese patients (body-mass index [BMI] ≥35 kg/m2) following minimally invasive adrenalectomy. Materials and Methods: A retrospective analysis of patients who underwent minimally invasive adrenalectomy at our institution between 2010 and 2023 was conducted. Two matching analyses were performed. The first analysis compared patients with BMI greater versus lower than 35 kg/m2. The second analysis compared outcomes between robotic and laparoscopic adrenalectomy in patients with a BMI ≥35 kg/m2. Results: A total of 278 patients were included in the study. The median tumor size was 29 mm. Adrenal tumors had similar laterality, and most were hormonally active (66.2%). The most common pathological diagnosis was pheochromocytoma (25.5%). No statistical difference was found in peri- and postoperative outcomes between patients with BMI ≥35 and <35 kg/m2 who underwent minimally invasive adrenalectomy. When the surgical approach was compared in severely obese patients, robotic adrenalectomy was associated with shorter hospital length of stay with similar operative time as the laparoscopic approach. Conclusions: Minimally invasive adrenalectomy is safe and feasible in patients with BMI ≥35 kg/m2. Robotic and laparoscopic approaches are both safe and efficient for the resection of adrenal tumors in severely obese patients.

BACKGROUND: This study investigated the impact of surgical modalities on surgeon wellbeing with a focus on burnout, job satisfaction, and interventions used to address neuromusculoskeletal disorders (NMSDs). METHODS: An electronic survey was sent to surgeons across an academic integrated multihospital system. The survey consisted of 47 questions investigating different aspects of surgeons' wellbeing. RESULTS: Out of 245 thoracic and abdominopelvic surgeons, 79 surgeons (32.2 â%) responded, and 65 surgeons (82 â%) were able to be categorized as having a dominant surgical modality. Compared to robotic surgeons, laparoscopic (p â= â0.042) and open (p â= â0.012) surgeons reported more frequent feelings of burnout. The number of surgeons who used any treatment/intervention to minimize the operative discomfort/pain was lower for robotic surgeons than the other three modalities (all p â< â0.05). CONCLUSIONS: NMSDs affect different aspects of surgeons' lives and occupations. Robotic surgery was associated with decreased feelings of burnout than the other modalities.
RESUMEN
BACKGROUND: Venous thromboembolism (VTE) is a major cause of morbidity and mortality after bariatric surgery, most often occurring after discharge within 30 days after surgery. OBJECTIVES: To determine the risk factors associated with VTE after either sleeve gastrectomy (SG) or Roux-en-Y gastric bypass (RYGB) and to develop a Bariatric Hypercoagulation Score (BHS) to predict 30-day adverse postoperative outcomes. SETTING: University hospital. METHODS: Using 2015-2018 data from the Metabolic and Bariatric Surgery Quality Improvement Program, a BHS was created by performing a logistic regression of "venous thromboembolism." The variables with the highest odds ratio (OR) were selected for the SG and RYGB groups. Then, the 30-day outcomes of low-risk (0-1), average-risk (2-3), and high-risk (≥4) BHS were compared. RESULTS: Similar risk factors for VTE were found in both the SG and RYGB groups; the highest OR was shown by history of deep vein thrombosis (SG: 3.54, RYGB: 3.05). Other related factors in both groups were history of pulmonary embolism, prolonged length of stay, Black race, and male sex. Conversely, unique risk factors such as dialysis (OR 1.81) was found in the SG group; meanwhile, prolonged operative time (OR 1.50) and age >60 years (OR 1.28) were for the RYGB group. When comparing the 30-day outcomes, BHS ≥4 had a significantly higher rate of complications (P < .001). CONCLUSIONS: SG and RYGB have some risk factors in common for VTE; however, dialysis was associated only with SG, and prolonged operative time and age >60 years were associated only with RYGB. BHS ≥4 showed higher 30-day adverse outcomes. The VTE-correlated variables require special consideration when assessing patients undergoing SG and RYGB.
