One anastomosis gastric bypass (OAGB), the third most commonly performed procedure worldwide, has shown excellent results in terms of weight loss and resolution of comorbidities compared with other bariatric surgeries. However, its use remains limited in various parts of the world due to postoperative complications. After the efficacy of this procedure was established, the focus of treatment shifted toward resolving postoperative complications. Protein-energy malnutrition after OAGB is one of the main issues that needs to be addressed. There are several operative options for patients who require revision surgery including reversal and conversion to Roux-en-Y gastric bypass (RYGB). The conversion from OAGB to RYGB is a feasible method that has shown excellent results when performed by experts in the field. Here, we present the case of a woman with symptoms of acute obstruction secondary to OAGB who underwent conversion to RYGB under emergent conditions.
