Patients undergoing bariatric surgery for GERD may very often require revision surgery

Key findings from this study are:

· 4412 patients required revisional surgery for GERD, encompassing 24% of all conversion procedures.

· Most patients underwent SG as their original surgery, constituting 80.1%.

· The revisional surgery for most patients was RYGB, constituting 84.4%.

· 527 patients experienced major complications.

· Ten patients died within 30 days of revisional surgery.

· Major complications included anastomotic leak (0.70%) and gastrointestinal bleeding (0.86%).

· Operative length, pre-operative antacid use, and RYGB were predictors of major complications.

This study is the largest to date on patients undergoing revisional surgery for GERD. The pathophysiology of GERD in bariatric surgery patients is still debated, but a better understanding could reduce the need for revisional procedures. They said that novel endoscopic techniques raise new questions as potential alternatives for primary and revisional bariatric procedures.
