Background:
The obesity epidemic has resulted in an accompanied increase in bariatric surgery volumes in the United States. The present study aims to analyze trends and indications for revision of bariatric operations.
Methods:
A retrospective review of patients who underwent revisional bariatric surgery at a multi-site single institution from 2000 to 2022.
Results:
901 patients were identified; the primary operations leading to revision was Roux-en-Y gastric bypass (RYGB) (n = 413), gastric banding (n = 276), sleeve gastrectomy (SG) (n = 157), and other (N = 55); with mean follow-up of 2.6 years.
Conclusions:
Bariatric revisions have varied over time related to the incidence and outcomes of the most popular primary operations. SG has become the most common operation undergoing revision. Weight regain or inadequate weight loss was the most common reason for revision, with majority of patients undergoing revision to RYGB. At our institution, revision to RYGB yielded the most significant improvement in results at most recent follow up.
