A572 Conversion of Vertical Sleeve Gastrectomy to Duodenal Switch is a Reliable Option for Weight Recidivism with Minimal Risk of Vitamin Deficiencies
The vertical sleeve gastrectomy (VSG) currently accounts for almost 60% of all bariatric surgeries in the US. Unfortunately, more than 50% of patients experience some degree of weight recidivism. The biliopancreatic diversion with duodenal switch (BPD-DS) is a highly malabsorptive procedure with better long-term weight loss. It isn ’t clear if patients have greater vitamin deficiencies.

A571 Oesophageal adenocarcinoma after conversion of sleeve gastrectomy to Roux-Y gastric bypass for gastroesophageal reflux. A case report.
Incidence of gastroesophageal reflux (GER) after sleeve gastrectomy (SG) is a concern considering the popularity of this procedure, lack of long-term data and theoretical risk of esophageal cancer development. Gastric bypass is considered the best therapeutic option for persisting reflux after SG. However up to 30% of patients suffer from post-operative GER.

A567 Baseline Personality Differences Between Sleeve Gastrectomy and Gastric Bypass Cohorts and their Association with Consecutive Follow-Up after Bariatric Surgery
We have previously shown that sleeve gastrectomy (SG) independently predicts both poor weight-loss and clinic-no-shows up to 2 years after bariatric surgery (BS). Given the association between follow-up and weight-loss, we hypothesized that baseline personality differences between SG versus gastric bypass (GB) may be contributory. Therefore, our aim was to compare personality traits between these cohorts and determine their association with consecutive post-operative follow-up.

Bariatric surgeries remain the most effective treatment for morbid obesity and obesity-related comorbidities1. Yet, despite substantial and durable weight loss and improvement in cardiometabolic profiles, an increasing body of evidence demonstrates that bariatric procedures exert a negative effect on bone density, microarchitecture, and strength, leading to an increased risk for fracture. Among the two most common bariatric procedures, sleeve gastrectomy (SG) and Roux-en-Y gastric bypass (RYGB), studies have shown declines in hip bone density ranging 5% to 11% within the first post-operative year2.
