How does sleeve gastrectomy impact long-term eating-related symptoms, distress, and behavior? A cross-sectional study using the BODY-Q patient-reported outcome measures.

BACKGROUND: Patients undergoing sleeve gastrectomy (SG) experience transformative changes in eating-related experiences that include eating-related symptoms, emotions, and habits. Long-term assessment of these endpoints with rigorous patient-reported outcome measures (PROMs) is limited. We assessed patients undergoing SG with the Body-Q Eating Module PROMs. METHODS: All patients evaluated at the Emory Bariatric Center were given the Body-Q Eating Modules questionnaire at preoperative/postoperative clinic visits. Rasch scores and prevalence of relevant endpoints were assessed across six time-points of interest: preoperatively, post-operative months 0-6, 7-12, 12-24, 24-36, and over 36. Student's t-test and Chi-square test were used for analysis. RESULTS: Overall, 1,352 questionnaires were completed pre-operatively and 493 postoperatively. Survey compliance was 81%. Compared to the pre-operative group, the post-operative group had lower BMI (39.7 vs. 46.4, p < 0.001) and higher age (46.3 vs. 44.9, p = 0.019). Beginning one year after SG, patients experience more frequent eating-related pain, nausea and constipation compared to pre-operative baseline (p < 0.05). They also more frequently experience eating-related regurgitation and dumping syndrome-related symptoms beginning post-operative year two (p < 0.05). In the first year after SG, patients more rarely feel eating-related embarrassment, guilt, and disappointment compared to pre-operative baseline (p < 0.05). These improvements disappear one year after SG, after which patients more frequently experience feeling out of control, unhappy, like a failure, disappointed, and guilty (p < 0.05). In the first year after SG, patients experience an increased frequency in positive eating behaviors (ate healthy foods, showed self-control, stopped before full; (p < 0.05). Only two eating-related behavior improvements persist long-term: feeling in control and eating the right amount (p < 0.05). CONCLUSIONS: Patients undergoing SG may experience more frequent eating-related symptoms, distress, and behavior in the long-term. These findings can enhance the pre-operative informed consent and guide development of a more tailored approach to postoperative clinical management such as more frequent visits with the dietician.

Achieving durable compliance with venous thromboembolism prophylaxis in bariatric surgery: 3-year data from a major academic medical center.

BACKGROUND: Metabolic and bariatric surgery (MBS) venous thromboembolism (VTE) prescribing practices vary widely. Our institutional VTE prophylaxis protocol has historically been unstandardized. OBJECTIVES: To create a standardized MBS VTE prophylaxis protocol, track protocol compliance, and identify barriers to protocol compliance and address them with Plan-Do-Study-Act (PDSA) cycles. SETTING: Single Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program-accredited academic hospital. METHODS: We conducted a retrospective study for all patients undergoing MBS (January 2019 to September 2022). A multidisciplinary group of bariatric clinicians reviewed literature and developed the following standardized VTE prophylaxis protocol: 5000 units preoperative subcutaneous (SC) heparin within 60 minutes of anesthesia induction and postoperative 40 mg SC low molecular weight heparin (LMWH) within 24 hours of surgery. This protocol was distributed to relevant clinical stakeholders. We assessed monthly compliance rates through chart review. Goal compliance was ≥90%. We identified sources of noncompliance and addressed them with PDSA methodology. RESULTS: A total of 796 patients were included. Preoperative heparin administration increased from a mean of 47% (107/228) preintervention to 96% (545/568) postintervention (P < .0001), and postoperative LMWH administration increased from 71% (47/66) to 96% (573/597, P = .0002). These compliance rates were sustained for 3 years. Barriers to protocol noncompliance included order set timing errors (n = 45), surgeon error (n = 44), surgeon discretion (n = 40), and nursing error (n = 20). No change in bleeding or VTE rates was observed. CONCLUSIONS: Developing a standardized VTE prophylaxis protocol, monitoring process measures, and engaging relevant stakeholders in PDSA cycles resulted in drastic and durable improvement in VTE prophylaxis compliance rates.

Robotic versus laparoscopic gastrectomy for adenocarcinoma in the US: a propensity score-matching analysis of 11,173 patients on oncological adequacy.

INTRODUCTION: Surgery remains the cornerstone treatment for gastric cancer. Previous studies have reported better lymphadenectomy with minimally invasive approaches. There is a paucity of data comparing robotic and laparoscopic gastrectomy in the US. Herein, we examined whether oncological adequacy differs between laparoscopic and robotic approaches. METHODS: The National Cancer Database was utilized to identify patients who underwent gastrectomy for adenocarcinoma between 2010 and 2019. A propensity score-matching analysis between robotic gastrectomy (RG) versus laparoscopic gastrectomy (LG) was performed. The primary outcomes were lymphadenectomy ≥ 16 nodes and surgical margins. RESULTS: A total of 11,173 patients underwent minimally invasive surgery for gastric adenocarcinoma between 2010 and 2019. Of those 8320 underwent LG and 2853 RG. Comparing the unmatched cohorts, RG was associated with a higher rate of adequate lymphadenectomy (63.5% vs 57.1%, p < .0.0001), higher rate of negative margins (93.8% vs 91.9%, p < 0.001), lower rate of prolonged length of stay (26.0% vs 29.6%, p < .0.001), lower 90-day mortality (3.7% vs 5.0%, p < 0.0001), and a better 5-year overall survival (OS) (56% vs 54%, p = 0.03). A propensity score-matching cohort with a 1:1 ratio was created utilizing the variables associated with lymphadenectomy ≥ 16 nodes. The matched analysis revealed that the rate of adequate lymphadenectomy was significantly higher for RG compared to LG, 63.5% vs 60.4% (p = 0.01), respectively. There was no longer a significant difference between RG and LG regarding the rate of negative margins, prolonged length of stay, 90-day mortality, rate of receipt of postoperative chemotherapy, and OS. CONCLUSIONS: This propensity score-matching analysis with a large US cohort shows that RG was associated with a higher rate of adequate lymphadenectomy compared to LR. RG and LG had a similar rate of negative margins, prolonged length of stay, receipt of postoperative chemotherapy, 90-day mortality, and OS, suggesting that RG is a comparable surgical approach, if not superior to LG.

Does the use of a suction calibration system (SCS) reduce stapler load firings and operative time? A randomized controlled trial comparing use of endoscopic calibration vs. SCS in laparoscopic sleeve gastrectomy.

BACKGROUND: It is critical to ensure appropriate and consistent sleeve size and orientation during laparoscopic sleeve gastrectomy (LSG). Various devices are used to achieve this, including weighted rubber bougies, esophagogastroduodenoscopy (EGD), and suction calibration systems (SCS). Prior reports suggest that SCSs may decrease operative time and stapler load firings but are limited by single-surgeon experience and retrospective design. We performed the first randomized controlled trial comparing SCS against EGD in patients undergoing LSG to investigate whether the SCS decreases the number of stapler load firings. METHODS: This was a randomized, non-blinded study from a single MBSAQIP-accredited academic center. Appropriate LSG candidates ≥ 18 years of age were randomized to EGD or SCS calibration. Exclusion criteria included prior gastric or bariatric surgery, detection of hiatal hernia before surgery, and intraoperative hiatal hernia repair. A randomized block design was employed controlling for body mass index, gender, and race. Seven surgeons employed a standardized LSG operative technique. The primary endpoint was the number of stapler load firings. Secondary endpoints were operative duration, reflux symptoms, and change in total body weight (TBW). Endpoints were analyzed via t-test. RESULTS: A total of 125 LSG patients (84% female) underwent study enrollment, with an average age of 44 ± 12 years and average BMI of 49 ± 8 kg/m2. Overall, 117 patients were randomized to receive EGD (n = 59) or SCS (n = 58) calibration. No significant differences in baseline characteristics were identified. The mean number of stapler load firings for EGD and SCS groups were 5.43 ± 0.89 and 5.31 ± 0.81, respectively (p = 0.463). The mean operative times for EGD and SCS groups were 94.4 ± 36.5 and 93.1 ± 27.9 min, respectively (p = 0.83). There were no significant differences in post-operative reflux, TBW loss, or complications. CONCLUSION: Use of EGD and SCS resulted in a similar number of LSG stapler load firings and operative duration. Additional research is needed to compare LSG calibration devices in different patients and settings to optimize surgical technique.

Gastric Cancer Surgery in the US: a Contemporary Trend Analysis of Lymphadenectomy and the Impact of Minimally Invasive Approaches.

BACKGROUND: The National Comprehensive Cancer Network guidelines recommend harvesting 16 or more lymph nodes for the adequate staging of gastric adenocarcinoma. This study examines the rate of adequate lymphadenectomy over recent years, its predictors, and its impact on overall survival(OS). STUDY DESIGN: The National Cancer Database was utilized to identify patients who underwent surgical treatment for gastric adenocarcinoma between 2006-2019. Trend analysis was performed for lymphadenectomy rates during the study period. Logistic regression, Kaplan-Meier survival plots, and Cox proportional hazard regression were utilized. RESULTS: A total of 57,039 patients who underwent surgical treatment for gastric adenocarcinoma were identified. Only 50.5% of the patients underwent a lymphadenectomy of ≥ 16 nodes. Trend analysis showed that this rate significantly improved over the years, from 35.1% in 2006 to 63.3% in 2019 (p < .0001). The main independent predictors of adequate lymphadenectomy included high-volume facility with ≥ 31 gastrectomies/year (OR: 2.71; 95%CI:2.46-2.99), surgery between 2015-2019 (OR: 1.68; 95%CI: 1.60-1.75), and preoperative chemotherapy (OR:1.49; 95%CI:1.41-1.58). Patients with adequate lymphadenectomy had better OS than patients who did not: median survival: 59 versus 43 months (Log-Rank: p < .0001). Adequate lymphadenectomy was independently associated with improved OS (HR:0.79; 95%CI:0.77-0.81). Laparoscopic and robotic gastrectomies were independently associated with adequate lymphadenectomy compared to open, OR: 1.11, 95%CI:1.05-1.18 and OR: 1.24, 95%CI:1.13-1.35, respectively. CONCLUSION: Although the rate of adequate lymphadenectomy improved over the study period, a large number of patients still lacked adequate lymph node dissection, negatively impacting their OS despite multimodality therapy. Laparoscopic and robotic surgeries were associated with a significantly higher rate of lymphadenectomy ≥ 16 nodes.

Extended postoperative venous thromboembolism prophylaxis after bariatric surgery: a comparison of existing risk-stratification tools and 5-year MBSAQIP analysis.

BACKGROUND: Venous thromboembolism (VTE) is a leading cause of 30-day mortality after metabolic and bariatric surgery (MBS). Multiple predictive tools exist for VTE risk assessment and extended VTE chemoprophylaxis determination. OBJECTIVE: To review existing risk-stratification tools and compare their predictive abilities. SETTING: MBSAQIP database. METHODS: Retrospective analysis of the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) database was performed (2015-2019) for primary minimally invasive MBS cases. VTE clinical factors and risk-assessment tools were evaluated: body mass index threshold of 50 kg/m2, Caprini risk-assessment model, and 3 bariatric-specific tools: the Cleveland Clinic VTE risk tool, the Michigan Bariatric Surgery Collaborative tool, and BariClot. MBS patients were deemed high risk based on criteria from each tool and further assessed for sensitivity, specificity, and positive predictive value. RESULTS: Overall, 709,304 patients were identified with a .37% VTE rate. Bariatric-specific tools included multiple predictors: procedure, age, race, gender, operative time, length of stay, heart failure, and dyspnea at rest; operative time was the only variable common to all. The body mass index cutoff and Caprini risk-assessment model had higher sensitivity but lower specificity when compared with the Michigan Bariatric Surgery Collaborative and BariClot tools. While the sensitivity of the tools varied widely and was overall low, the Cleveland Clinic tool had the highest sensitivity. The bariatric-specific tools would have recommended extended prophylaxis for 1.1%-15.6% of patients. CONCLUSIONS: Existing MBS VTE risk-assessment tools differ widely for inclusion variables, high-risk definition, and predictive performance. Further research and registry inclusion of all significant risk factors are needed to determine the optimal risk-stratified approach for predicting VTE events and determining the need for extended prophylaxis.

Utilizing Simulation to Evaluate Robotic Skill Acquisition and Learning Decay.

BACKGROUND: We aim to evaluate how new robotic skills are acquired and retained by having participants train and retest using exercises on the robotic platform. We hypothesized that participants with a 3-month break from the robotic platform will have less learning decay and increased retention compared with those with a 6-month break. METHODS: This was a prospective randomized trial in which participants voluntarily enrolled and completed an initial training phase to reach proficiency in 9 robot simulator exercises. They were then instructed to refrain from practicing until they retested either 3 or 6 months later. This study was completed at an academic medical center within the general surgery department. Participants were medical students, and junior-level residents with minimal experience in robotic surgery were enrolled. A total of 27 enrolled, and 13 participants completed the study due to attrition. RESULTS: Overall, intragroup analysis revealed that participants performed better in their retest phase compared with their initial training in terms of attempts to reach proficiency, time for completion, penalty score, and overall score. Specifically, during the first attempt in the retesting phase, the 3-month group did not deviate far from their final attempt in the training phase, whereas the 6-month group experienced significantly worse time to complete and overall score in interrupted suturing {[-4 (-18 to 20) seconds vs. 109 (55 to 118) seconds, P =0.02] [-1.3 (-8 to 1.9) vs. -18.9 (-19.5 to (-15.0)], P =0.04} and 3-arm relay {[3 (-4 to 23) seconds vs. 43 (30 to 50) seconds, P =0.02] [0.4 (-4.6 to 3.1) vs. -24.8 (-30.6 to (-20.3)], P =0.01] exercises. In addition, the 6-month group had a significant increase in penalty score in retesting compared with the 3-month group, which performed similarly to their training phase [3.3 (2.7 to 3.3) vs. 0 (-0.8 to 1.7), P =0.03]. CONCLUSIONS: This study identified statistically significant differences in learning decay, skills retention, and proficiency between 3-month and 6-month retesting intervals on a robotic simulation platform.

S136-operationalizing an enhanced recovery protocol after bariatric surgery: single institutional pilot experience forging data-driven standard work.

BACKGROUND: Enhanced recovery protocols (ERPs) after metabolic and bariatric surgery (MBS) may help decrease length of stay (LOS) and postoperative nausea/vomiting but implementation is often fraught with challenges. The primary aim of this pilot study was to standardize a MBS ERP with a real-time data support dashboard and checklist and assess impact on global and individual element compliance. The secondary aim was to evaluate 30 day outcomes including LOS, hospital readmissions, and re-operations. METHODS AND PROCEDURES: An ERP, paper checklist, and virtual dashboard aligned on MBS patient care elements for pre-, intra-, and post-operative phases of care were developed and sequentially deployed. The dashboard includes surgical volumes, operative times, ERP compliance, and 30 day outcomes over a rolling 18 month period. Overall and individual element ERP compliance and outcomes were compared pre- and post-implementation via two-tailed Student's t-tests. RESULTS: Overall, 471 patients were identified (pre-implementation: 193; post-implementation: 278). Baseline monthly average compliance rates for all patient care elements were 1.7%, 3.7%, and 6.2% for pre-, intra-, and post-operative phases, respectively. Following ERP integration with dashboard and checklist, the intra-operative phase achieved the highest overall monthly average compliance at 31.3% (P < 0.01). Following the intervention, pre-operative acetaminophen administration had the highest monthly mean compliance at ≥ 99.1%. Overall TAP block use increased 3.2-fold from a baseline mean rate of 25.4-80.8% post-implementation (P < 0.01). A significant decrease in average intra-operative monthly morphine milligram equivalents use was noted with a 56% drop pre- vs. post-implementation. Average LOS decreased from 2.0 to 1.7 days post-implementation with no impact on post-operative outcomes. CONCLUSION: Implementation of a checklist and dashboard facilitated ERP integration and adoption of process measures with many improvements in compliance but no impact on 30 day outcomes. Further research is required to understand how clinical support tools can impact ERP adoption among MBS patients.

Development of a laparoscopic surgical skills simulation curriculum: Enhancing resident training through directed coaching and closed-loop feedback.

BACKGROUND: Performance feedback through peer coaching and rigorous self-assessment is a critical part of technical skills improvement. However, formal collaborative programs using operative video-based skills assessments to generate peer coaching feedback have only been validated among attending surgeons. In this study, we developed a unique longitudinal, simulation video-based laparoscopic skills resident curriculum using video-based peer coaching and evaluated its association with skills acquisition among surgical trainees. METHODS: The laparoscopic simulation curriculum consists of a pre-practice laparoscopic skill video recording, followed by receipt of directed coaching and feedback on performance from a faculty coach, a peer coach, and self-coaching. Residents then completed 6 weeks of feedback-directed practice and submitted a second post-practice laparoscopic skill video recording of the same skill, which was evaluated by a minimally invasive surgery expert grader. All general surgery residents in a single institution were enrolled, with 107 residents completing the curriculum in its initial 2 years. RESULTS: Overall, more than two-thirds of residents achieved skills proficiency on their expert assessments, with similar rates of residents achieving skills proficiency at all postgraduate year levels. Significant improvements between the pre-practice assessments and post-practice assessments were most frequently seen in the instrument handling, precision, and motion & flow categories (P < .05 each). Faculty provided the highest number and proportion of closed-loop comments; residents' self-coaching feedback had the lowest number of closed-loop comments, with 83% of self-assessments containing none. CONCLUSION: In this study, we describe the successful implementation of a longitudinal laparoscopic skills video-based coaching curriculum designed to improve residents' laparoscopic technical abilities through iterative directed practice supplemented by formative closed-loop feedback. This feasible, reproducible, and low-cost simulation curriculum can be adapted to other training programs and skills acquisition endeavors. This program also prepares trainees for ongoing performance feedback after completion of residency through rigorous self-assessment and peer-to-peer coaching.

Laparoscopic Paraesophageal Hernia Repair and Pulmonary Embolism.

OBJECTIVE: Pulmonary embolism (PE) following laparoscopic paraesophageal hernia repair (PEHR) is rare but occurs at a higher frequency than other laparoscopic procedures. We describe a series of patients who developed PEs after PEHR in hopes of capturing potential risk factors for further study. MATERIALS AND METHODS: Five cases of PE after PEHR were observed between 2017 and 2018. Individual and perioperative risk factors, and postoperative courses were reviewed. RESULTS: Patients had a mean age of 73 years (range, 59 to 86). All were female. Two patients presented acutely. Three patients underwent revisional surgery. The average procedure duration was 248 minutes (range, 162 to 324). All patients had gastrostomy tubes placed. The diagnosis of PE occurred within 3 to 19 days postoperatively. Four were treated with 3 months of oral anticoagulation; 1 was managed expectantly. CONCLUSIONS: Highly complex cases, marked by revisional status, need for mesh, large hernia size, and percutaneous endoscopic gastrostomy placement are likely at increased risk for PEs. Preoperative venous thromboembolism chemoprophylaxis should be considered in the majority of laparoscopic PEHR patients.

Perioperative anxiety and depression in patients undergoing abdominal surgery for benign or malignant disease.

BACKGROUND AND OBJECTIVES: Etiologies, levels, and associated factors of psychological distress in cancer patients facing surgery are poorly defined. We conducted a prospective comparative study of perioperative anxiety and depression in patients undergoing abdominal surgery for either malignant or benign disease. METHODS: With Institutional Review Board approval, patients consenting for surgery at our institution were enrolled. Surveys were completed at a preoperative visit and within 2 weeks of a postoperative appointment. Participants listed their top three sources of anxiety, and completed the Patient Health Questionnaire-9 and the General Anxiety Disorder-7. RESULTS: A total of 79 patients completed the preoperative assessment and 44 (58.7%) finished the postoperative survey. Forty-one were male (51.9%), 12 (15.2%) had a psychiatric comorbidity (PSYHx), and 47 (59.5%) had cancer. Perioperative anxiety and depression did not differ by malignancy status. Patients were most concerned about surgery (22.5%) preoperatively and finances (27.9%) postoperatively. PSYHx, frailty, insurance status, and opioid use were all associated with perioperative psychological distress. CONCLUSIONS: Cancer patients did not have significantly higher levels of perioperative psychological distress compared with benign controls. Socioeconomic worries are prevalent throughout the perioperative period, and efforts to alleviate distress should focus on providing adequate counseling.

Laparoscopic Sleeve Gastrectomy Outcomes in Patients with Polycystic Ovary Syndrome.

Polycystic ovary syndrome (PCOS) is a common disease among the bariatric population. However, there are limited data regarding the impact of laparoscopic sleeve gastrectomy (SG) on these patients. The study was conducted at University Hospital, United States. The purpose of this study was to examine per cent excess body weight loss (%EWL) and diabetes control in patients who have PCOS compared with those without PCOS. A total of 550 female patients underwent SG between December 2011 and October 2016. Retrospective analysis was completed to include follow-up data at 1, 3, 6, and 12 months and yearly after that. Outcomes measured were %EWL and hemoglobin A1c (HgbA1c). The mean and median follow-up for the entire cohort was 21 and 15 months, respectively. Seventy-eight per cent of patients completed at least 12 months of follow-up for %EWL, although only 21 per cent had similar follow-up for HgbA1c. PCOS patients had similar age (36.3 vs 36.2 years, P = 0.90), preoperative BMI (47.2 vs 47.2, P = 0.99), preoperative HgbA1c (6% vs 5.8%, P = 0.31), conversion rate to gastric bypass, and other associated comorbidities compared with non-PCOS comparisons. There was no difference in %EWL at 12-month (49.7% vs 53.1%, P = 0.53) or 24-month (43% vs 49.8%, P = 0.46) postoperative intervals. There was no difference in absolute change of HgbA1c at 12 months (-0.47% vs -0.67%, P = 0.39). SG has equivalent short-term results in %EWL and reduction in HgbA1c for patients who have PCOS and those who do not.

Publication patterns and the impact of self-citation among minimally invasive surgery fellowships.

INTRODUCTION: The h-index is a widely utilized academic metric that measures both productivity and citation impact. The purpose of this study is to define the impact of self-citation among minimally invasive surgery (MIS) fellowship program directors. METHODS: Through the Fellowship Council's website, all program directors and associate program directors from the 148 MIS fellowship programs were identified. Using the Scopus database, we calculated the number of publications, citations, self-citations, and h-index for each surgeon. RESULTS: A total of 274 surgeons were identified. The mean number±SD of publications, citations, and h-index for the cohort were 60.5 ±â€¯77.2, 1765 ±â€¯4024, and 16.0 ±â€¯15.0, respectively. The self-citation rate for the entire cohort was 3.23%. Excluding self-citations reduces the mean number of citations to 1708 ±â€¯3887 and h-index to 15.8 ±â€¯14.6. The h-index remained unchanged for 77% (210/274) of surgeons. Only 5% (15/274) of surgeons had a change in h-index of greater than one integer and no surgeon had a change greater than three integers. CONCLUSION: Self-citation is infrequent and has a minimal impact on the academic profile of program directors of MIS fellowships.

Robotic-assisted Laparoscopic Repair of Scrotal Inguinal Hernias.

BACKGROUND: Scrotal inguinal hernias represent a challenging surgical pathology. Although some advanced laparoscopists can repair these hernias through a minimally invasive approach, open repair is considered the technique of choice for most surgeons. The purpose of this study is to show our results of robotic-assisted laparoscopic repair of scrotal inguinal hernias. PATIENTS AND METHODS: We reviewed the charts of 14 patients with inguinoscrotal hernias who underwent robotic-assisted transabdominal preperitoneal (TAPP) hernia repair. Mean follow-up was 7 months. The European Registry for Abdominal Wall Hernia Quality of Life score, a 90-point scale, was utilized to quantify patient reported outcomes. RESULTS: Robotic TAPP repair was successful in all 14 patients. Average case duration was 100 minutes (78 to 140 min) for unilateral hernias and 208 minutes (166 to 238 min) for bilateral hernias. Trainees were involved in 93% (13/14) of cases. There were no recurrences. Three patients developed postoperative seromas. The mean European Registry for Abdominal Wall Hernia Quality of Life score was 3.7 (0 to 10). CONCLUSIONS: Scrotal hernias can be safely repaired using robotic-assisted TAPP methods with low morbidity and favorable patient reported outcomes.

Barriers to Enhanced Recovery after Surgery after Laparoscopic Sleeve Gastrectomy.

BACKGROUND: Enhanced Recovery after Surgery (ERAS) protocols lead to expedited discharges and decreased cost. Bariatric centers have adopted such programs for safely discharging patients after sleeve gastrectomy (LSG) on the first postoperative day (POD1). Despite pathways, some bariatric patients cannot be discharged on POD1. STUDY DESIGN: We performed a retrospective review of patients undergoing LSG, from 2013 through 2016, in a center of excellence, using a standardized enhanced recovery pathway. Patient variables and perioperative factors were analyzed, including multivariate regressions, for predictors of early discharge. RESULTS: There were 573 patients who underwent LSG (83% female, mean age of 46.3 ± 11.7 years, and BMI of 46.0 ± 6.6 kg/m2). Mean hospital stay was 1.7 days ± 1.0 SD. Early discharge occurred in 38.2% of patients. Independently, early operating room start times and treated obstructive sleep apnea were associated with earlier discharge (p < 0.05). In contrast, preoperative opioid use, history of psychiatric illness, chronic kidney disease, and revision cases delayed discharge (p < 0.05). Age, sex, American Society of Anesthesiologists (ASA) class, diabetes, congestive heart failure, hypertension, distance to home, and insurance status were not significant. On regression modeling, early operating room start time and treated obstructive sleep apnea (OSA) reduced length of stay (LOS) (p < 0.05), while creatinine >1.5 mg/dL, ejection fraction < 50%, and increased case duration increased LOS (p < 0.05). Fifteen patients were readmitted within 30 days (2.6%). CONCLUSIONS: Several clinical and operative factors affect early discharge after LSG. Knowing factors that enhance the success of ERAS as well as the causes and corrections for failed implementation allow teams to optimally direct care pathway resources.

Biliary reconstruction options for bile duct stricture in patients with prior Roux-en-Y reconstruction.

Comprehensive description with illustrations of the 4 biliary reconstruction options for bile duct injury in patients with history of Roux-en-Y gastric bypass.

Reconstruction Options for Pancreaticoduodenectomy in Patients with Prior Roux-en-Y Gastric Bypass.

BACKGROUND: Patients with prior Roux-en-Y gastric bypass (RYGB) operations for weight loss present reconstruction challenges during a pancreaticoduodenectomy (PD). With over 60,000 RYGB performed annually, the increasing odds of encountering such patients during a PD make it imperative to understand the RYGB anatomy and anticipate reconstruction options. This article describes the possible reconstruction options and their rationale. METHODS: We reviewed our PD reconstruction options, compared them to what have been described in the literature, and derived a consensus from internal conferences comprising bariatric and hepatopancreatobiliary surgeons to describe known reconstruction options. RESULTS: In general, reconstruction options can include one of three options: (1) remnant gastrectomy, (2) preservation of gastric remnant, or (3) reversal of gastric bypass. CONCLUSION: This article describes individualized reconstruction options for RYGB patients undergoing PD. The reconstruction options can be tailored to the needs of the patient.

Surgical Technique for Laparoscopic Removal of a Magnetic Lower Esophageal Sphincter Augmentation Device.

BACKGROUND: Nissen fundoplication is the current gold standard for surgical management of gastroesophageal reflux disease; however, a magnetic antireflux device is now an alternative surgical procedure. The early literature shows good reflux control with minimal complications, and therefore placement of these devices is growing in popularity. As more of these devices are placed, there will be cases in which they will need to be removed. A laparoscopic method for removing the device is presented here. MATERIALS AND METHODS: We present a case of a 42-year-old female with history of gastroesophageal reflux who underwent a laparoscopic placement of a magnetic lower esophageal sphincter augmentation device and repair of a small hiatal hernia. She had a complicated postoperative course before presenting to our institution with a 2-year history of persistent dysphagia and requesting the device be removed. Laparoscopic removal of the device was performed. RESULTS: After laparoscopic removal of the patient's magnetic lower esophageal sphincter augmentation device, she had subjective improvement in her dysphagia but is now being medically managed for gastroesophageal reflux and for delayed gastric emptying. CONCLUSIONS: Laparoscopic removal of magnetic lower esophageal sphincter augmentation devices will sometimes be necessary and may be challenging if the surgeon encounters significant scar tissue around the gastroesophageal junction. Postoperative complications are similar to those encountered with foregut surgeries and include postoperative delayed gastric emptying.

Transanal Minimally Invasive Surgery (TAMIS): Standardizing a Reproducible Procedure.

BACKGROUND: The recent introduction of transanal minimally invasive surgery (TAMIS) offers a safe and cost-effective method for the local resection of rectal neoplasms. The ability to standardize a technique for TAMIS will lead to the most reproducible outcomes and enable teaching. METHODS: A retrospective, IRB-approved chart review was conducted of 32 patients who underwent the TAMIS procedure at one institution over a 3-year period. RESULTS: TAMIS was performed for 11 benign and 21 malignant lesions. The majority of resections were full thickness (29/32) and all were R0. Average distance from the anal verge was 7.5 ± 3 cm, defect circumference was 43.7 ± 10%, operative time was 131 ± 80 min, and length of stay was 1.1 ± 1 days. Two patients had morbidities requiring readmission and further treatment for (1) an aspiration pneumonia with CHF exacerbation and (2) a rectal abscess. CONCLUSIONS: This report outlines an operative technique for TAMIS that is reproducible for the excision of rectal lesions, associated with low morbidity.
