Endoscopic stenting for laparoscopic sleeve gastrectomy leaks

Area of Science:

• Gastroenterology
• Bariatric Surgery
• Minimally Invasive Surgery

Background:

• Laparoscopic sleeve gastrectomy (LSG) is a common bariatric procedure.
• Staple-line leaks occur in 1.5-5% of LSG patients.
• Endoscopic stent placement is an emerging treatment for LSG leaks.

Purpose of the Study:

• To evaluate the rate of staple-line leaks after LSG.
• To assess the efficacy of endoscopic stent placement for managing LSG leaks.
• To analyze outcomes of stent placement in a patient cohort.

Main Methods:

• Retrospective analysis of 236 LSG patients (Jan 2010 - Aug 2014).
• Four patients with post-LSG leaks were treated with self-expandable coated stents (Hanora®).
• Stent placement, duration, and removal outcomes were recorded.

Main Results:

• Four post-LSG staple-line leaks were successfully treated with endoscopic stents.
• All patients achieved leak healing after stent removal (1-5 months).
• Stent revisions were needed for migration (1) and breakage (1).

Conclusions:

• Endoscopic stent placement is an effective treatment for LSG staple-line leaks.
• Early stent placement, following sepsis control, shows promising results.
• Physician expertise may influence the success of early stent placement.
