Abstract
BACKGROUND: One-anastomosis gastric bypass (OAGB) was established as a recognized bariatric procedure in the 2018 International Federation for the Surgery of Obesity and Metabolic Disorders (IFSO) position statement. This study evaluates the outcomes of revisional OAGB (rOAGB) after a restrictive index procedure, and to compare it to revisional RYGB (rRYGB). METHODS: A literature search was performed according to the PRISMA guidelines on papers published from inception till February 2020. Original studies involving patients who underwent rOAGB after a primary failed restrictive procedure were included. The primary outcome measured was postrOAGB weight loss. Secondary outcome measures include comorbidity resolution, operative duration, length of stay, morbidity, and mortality. RESULTS: A total of 21 studies with 1377 patients were included. Five studies compared rOAGB versus rRYGB. Majority of the patients (76%) were female, with mean age of 43.5 years old. Mean body mass index (BMI) before revisional surgery was 41.6 kg/m2. The most common biliopancreatic limb length was 200 cm. Percentage of excess weight loss after rOAGB increases to a maximum of 76.0% at 48 months postsurgery. rOAGB resulted in a pooled prevalence of diabetes, hypertension, hyperlipidemia, and obstructive sleep apnea resolution of 74.9%, 48.4%, 63.2%, and 75.7% respectively. When compared to rRYGB, rOAGB demonstrated greater weight loss, comparable metabolic syndrome resolution, but with a shorter operating time. Morbidity and mortality rates were low across all studies. CONCLUSIONS: rOAGB has potential as an alternative revisional surgery, with weight loss profiles and rates of metabolic syndrome resolution that are comparable to rRYGB.
