Summary

Revisional sleeve gastrectomy (ReSG) is a safe and effective option for patients experiencing weight loss failure or severe reflux after initial laparoscopic sleeve gastrectomy (LSG). This procedure demonstrated significant excess weight loss and improved outcomes in a retrospective study.

Area of Science:

  • Bariatric surgery
  • Minimally invasive surgery
  • Gastroenterology

Background:

  • Laparoscopic sleeve gastrectomy (LSG) is a popular bariatric procedure.
  • Long-term LSG outcomes can include weight loss failure and severe gastroesophageal reflux disease (GERD).
  • These complications may necessitate revisional surgery.

Purpose of the Study:

  • To evaluate the safety and efficiency of revisional sleeve gastrectomy (ReSG).

Main Methods:

  • Retrospective analysis of 61 patients undergoing ReSG between October 2008 and October 2014.
  • Patients had prior LSG with documented weight loss failure or GERD.
  • Radiologic evaluation (gastrografin swallow, CT scan volumetry) guided treatment algorithms.

Main Results:

  • ReSG was performed for insufficient weight loss (45.9%) or weight regain (47.5%), with 4 patients for GERD.
  • Mean BMI decreased from 39.4 kg/m² to 29.2 kg/m² post-ReSG.
  • Mean percentage of excess weight loss (%EWL) was 58.5% at a mean follow-up of 20 months.
  • The procedure was completed laparoscopically with low complication rates (hematoma, gastric stenosis).

Conclusions:

  • Revisional sleeve gastrectomy (ReSG) appears to be a viable surgical option for managing primary LSG failures.
  • Further prospective studies are needed to compare ReSG with other bariatric revisions like laparoscopic Roux-en-Y gastric bypass or duodenal switch.
