Abstract

One anastomosis gastric bypass is now an accepted bariatric procedure in many countries. A rare but serious complication of OAGB is perforation of marginal ulcer with 0.5–1% incidence that needs urgent diagnosis and intervention. In cases of complicated or refractory ulcers, conversion to RYGB could be a definitive therapy.

Key Points

• Conversion to RYGB may have indication in complicated marginal ulcers or cases with intractable symptoms.
