A435 Laparoscopic Sleeve Gastrectomy Is Successful in Decreasing Weight and Insulin Requirements in Patients with Type I Diabetes Mellitus
While there exists robust data to suggest that laparoscopic sleeve gastrectomy (LSG) is successful in the treatment of type II diabetes mellitus, there remains a paucity of evidence on the use of this surgery in patients with type I diabetes mellitus (T1DM). Previous literature looking into bariatric surgery for patients with T1DM has primarily focused on Roux-en-Y gastric bypass, which is now less commonly performed than LSG in the United States.

A331 Standard Laparoscopic Sleeve Gastrectomy vs Laparoscopic Sleeve Gastro-Omento-Pexy Technique and GERD: A Retrospective Case Control Study
Laparoscopic sleeve gastrectomy (LSG) affords patients excellent long term excess weight loss; however, one of the primary problems reported with this procedure is new onset or worsening gastro-esophageal reflux (GERD). Studies show the rate of de novo reflux after LSG to be 47.8%. Long-term GERD portends poor quality of life and increases the risk of esophageal cancer. We propose modifying the LSG by reattaching the omentum to the “new” greater portion of the sleeve stomach reduces the incidence of GERD by restoring natural anatomy.
