One anastomosis gastric bypass (OAGB), considered an alternative to Roux-en-Y gastric bypass, is becoming an increasingly common procedure. It shows excellent results in terms of weight reduction and remission of metabolic disease. Among the advantages of OAGB is the lack of internal hernia due to the absence of jejuno-jejunal anastomosis. However, internal herniation in OAGB is not impossible, and multiple cases have been mentioned in the literature. We describe a laparoscopic revisional surgery of internal hernia in a patient with a 2-month history of OAGB.
Keywords: OAGB; bariatric surgery; internal hernia; mini-gastric bypass surgery; obesity; small bowel obstruction.
