Background

Bariatric Surgery has been a safe and effective treatment for morbid obesity for many decades. As we continue to learn from our experiences, there has also been an increased incidence of revisional bariatric surgery. This includes Laparoscopic gastric banding (LGB) to Laparoscopic Sleeve Gastrectomy (LSG) or Laparoscopic Roux-en-Y Gastric Bypass (LRYGB), or LSG to LRYGB among others. Revisions can occur secondary to unsatisfactory weight loss, complications or long term sequalae such as worsening reflux. This study aims to determine whether revisional bariatric surgery can be done safely as a same day discharge procedure. We will perform a retrospective review of same-day bariatric surgeries performed between October 2021 and December 2023. Our primary study endpoints included the 30-day rate of ED visits, readmissions, reoperations, mortality and morbidity based on the Clavien-Dindo classification. Several statistical analyses were performed, including a non-inferiority analysis with an assigned a non-inferiority margin of 5% when compared to the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) Semiannual Report (SAR).

Results

Out of 47 patients included, 17 (36.1%) underwent LGB to LSG, 9 (19%) underwent LGB to LRYGB, and 21 (44.7%) underwent LSG to LRYGB. We are still in the process of gathering our data.

Conclusions

We hope to show that same day revisional bariatric surgery non-inferior with regards to the rate of readmissions, reoperations, morbidity and mortality when compared to the nationally accepted rates for these specific procedures reported in the MBSAQIP SAR.
