Trends in bariatric surgery training: bariatric operations performed by Fellowship Council trainees from 2012 to 2019.

BACKGROUND: The American Society for Metabolic and Bariatric Surgery (ASMBS) Fellowship Certificate was created to ensure satisfactory training and requires a minimum number of anastomotic cases. With laparoscopic sleeve gastrectomy becoming the most common bariatric procedure in the United States, this may present a challenge for fellows to obtain adequate numbers for ASMBS certification. OBJECTIVES: To investigate bariatric fellowship trends from 2012 to 2019, the types, numbers, and approaches of surgical procedures performed by fellows were examined. SETTING: Academic training centers in the United States. METHODS: Data were obtained from Fellowship Council records of all cases performed by fellows in ASMBS-accredited bariatric surgery training programs between 2012 and 2019. A retrospective analysis using standard descriptive statistical methods was performed to investigate trends in total case volume and cases per fellow for common bariatric procedures. RESULTS: From 2012 to 2019, sleeve gastrectomy cases performed by all Fellowship Council fellows nearly doubled from 6,514 to 12,398, compared with a slight increase for gastric bypass, from 8,486 to 9,204. Looking specifically at bariatric fellowships, the mean number of gastric bypass cases per fellow dropped over time, from 91.1 cases (SD = 46.8) in 2012-2013 to 52.6 (SD = 62.1) in 2018-2019. Mean sleeve gastrectomy cases per fellow increased from 54.7 (SD = 31.5) in 2012-2013 to a peak of 98.6 (SD = 64.3) in 2015-2016. Robotic gastric bypasses also increased from 4% of all cases performed in 2012-2013 to 13.3% in 2018-2019. CONCLUSIONS: Bariatric fellowship training has seen a decrease in gastric bypasses, an increase in sleeve gastrectomies, and an increase in robotic surgery completed by each fellow from 2012 to 2019.

Metabolic Surgery Outcomes in U.S. Patients with Class I Obesity.

Background: Although numerous studies outside the United States (U.S.) have explored weight loss and comorbidity resolution among patients with class I obesity (body mass index [BMI] 30-34.9 kg/m2) after metabolic surgery, few U.S.-based studies have been conducted. Objective: Our aim was to compare weight loss and comorbidity resolution among U.S. patients with class I obesity, who underwent laparoscopic sleeve gastrectomy (LSG) versus Roux-en-Y gastric bypass (RYGB). Methods: Weight loss and comorbidity data among only patients with class I obesity, who underwent LSG or RYGB, were examined. Between April 2009 and April 2017, 1215 metabolic surgeries were performed with 30 patients meeting the inclusion criteria (17 LSG and 13 RYGB). Results: Percent total weight loss (%TWL) for LSG peaked at 12 months (20.85%), while RYGB %TWL peaked at 18 months (21.65%). Percent excess weight loss (%EWL) peaked at 12 months after LSG (83.59%) and 18 months after RYGB (98.29%). Overall follow-up was 56.3%, 36.7%, and 43.3% at 12, 18, and 24 months. LSG and RYGB were both successful with regard to resolution of medical comorbidities at 12 months. Conclusion: RYGB and LSG appear to have similar, successful outcomes among U.S. patients with class I obesity for weight loss and comorbidity resolution.

Appendiceal torsion in Ehlers-Danlos syndrome: A case report of a rare phenomenon in a rare disease.

INTRODUCTION: Appendiceal torsion is a rare phenomenon with only a few reported cases and never in a patient with Ehlers-Danlos syndrome (EDS). We present the first case of appendiceal torsion leading to acute appendicitis in a patient with EDS. PRESENTATION OF CASE: A 36-year-old male with history of musculoskeletal EDS presented with one week of abdominal pain localizing to the right lower quadrant. He was evaluated in the emergency department with a complete set of labs and CT abdomen/pelvis. The CT scan showed acute appendicitis, but did not mention any appendiceal torsion. He was taken to the operating room for a standard laparoscopic appendectomy. Intraoperatively, there was inflammation at the tip of the appendix with a 270-degree torsion of the mid-appendix and mesoappendix. After untwisting, the appendix was safely removed from the base of the cecum. Patient recovered well postoperatively and no masses or tumors were identified on final pathology. DISCUSSION: Primary appendiceal torsion occurs without an identifiable cause and secondary torsion occurs due to pathology such as carcinoid tumor or other masses. Patients with EDS may be more prone to either torsion as they have hyperelastic skin, joints and ligaments. EDS patients require special workup prior to any operation including cardiopulmonary evaluation and may have unique postoperative complications. CONCLUSION: The ligamentous hypermobility of EDS may have predisposed our patient to appendiceal torsion and acute appendicitis. This is a rare phenomenon and may be underdiagnosed in EDS patients. Practitioners should be aware of this manifestation of EDS.

Systematic review and meta-analysis of Roux-en-Y gastric bypass against laparoscopic sleeve gastrectomy for amelioration of NAFLD using four criteria.

Nonalcoholic fatty liver disease (NAFLD) prevalence is rising worldwide, as a direct consequence of the obesity epidemic. Bariatric surgery provides proven NAFLD amelioration, although questions remain regarding whether Roux-en-Y gastric bypass (RYGB) or laparoscopic sleeve gastrectomy (LSG) is more effective. To answer this question, we conducted a systematic review and meta-analysis exclusively comparing RYGB and LSG for amelioration of NAFLD using 4 separate criteria: alanine transaminase, aspartate transaminase, NAFLD activity score, and NAFLD fibrosis score. Our search included 1290 initial studies, which were narrowed to 20 final studies in the meta-analysis. Overall, both RYGB and LSG significantly improved alanine transaminase, aspartate transaminase, NAFLD activity score, and NAFLD fibrosis score postoperatively. Direct comparisons of RYGB to LSG in any of the 4 criteria failed to demonstrate superiority. Our findings corroborate the current literature showing that bariatric surgery significantly improves biochemical and histologic parameters in patients with NAFLD. The novel individual comparisons of 4 criteria failed to show superiority between RYGB and LSG in ameliorating NAFLD. Despite several limitations, our study can assist clinicians by supporting the notion that RYGB and LSG may be equally efficacious in ameliorating NAFLD.
