Impact of Abdominal Lipectomy on Post-Sleeve Gastrectomy Surgery Weight Loss.

Abstract

Abdominal lipectomy after bariatric surgery is recommended because of residual excess skin resulting in difficulty with maintaining hygiene, recurrent infections, and functional impairment, interfering with daily activities. There is a dearth of literature examining weight loss outcomes in patients undergoing abdominal lipectomy post sleeve gastrectomy (SG). The purpose of this study was to examine whether post-SG patients who received abdominal lipectomy achieved greater percent excess weight loss (%EWL) than post-SG patients who did not receive abdominal lipectomy. Retrospective study of patients who underwent minimally invasive SG at the University of Illinois Hospital and Health Sciences System from March 2008 to June 2015 was conducted. The cohort was divided into 2 groups: patients who underwent abdominal lipectomy after SG (PS-SG) and patients who underwent SG alone (SG). Demographics, comorbidities, and %EWL were examined. Twenty-nine patients were included in the PS-SG group versus 287 patients in the SG group. Significant differences were found in %EWL at 24 (P < 0.0001), 36 (P < 0.005), and more than 36 months (P < 0.005) follow-up between groups, with a greater %EWL in patients in the PS-SG group versus the SG group. This preliminary study revealed that patients in the PS-SG group achieved greater %EWL than patients with SG alone. Although larger studies are needed, this study supports using abdominal lipectomy as an adjunctive procedure to assist with long-term weight loss as part of the overall treatment of bariatric surgery patients.
