Stent Management of Leaks After Bariatric Surgery: a Systematic Review and Meta-analysis

Area of Science:

• Gastroenterology
• Bariatric Surgery
• Endoscopic Interventions

Background:

• Gastrointestinal leaks are serious complications following bariatric surgery.
• Endoscopic management with self-expanding stents shows promise for treating these leaks.

Purpose of the Study:

• To systematically review and meta-analyze the effectiveness of self-expanding stents for managing gastrointestinal leaks post-bariatric surgery.
• To assess primary outcomes including leak closure, stent migration, and reoperation rates.

Main Methods:

• A systematic review and meta-analysis of studies involving self-expanding stent placement for gastrointestinal leaks after obesity surgery.
• Analysis of 488 patients, focusing on successful leak closure, stent migration, and reoperation rates.

Main Results:

• Successful leak closure was achieved in 85.89% of patients.
• Stent migration occurred in 18.65% and reoperation was needed in 13.54% of cases.
• No deaths were directly attributed to stent placement complications.

Conclusions:

• Endoscopic self-expanding stent placement is a highly effective treatment for bariatric surgery leaks in selected patients, with low mortality.
• Future research should focus on minimizing stent migration and reoperation rates.
