Background: One of the most important complications of the One Anastomosis Gastric Bypass (OAGB) is enterobilioacid reflux (EBAR). We report the concept of the Long Pouch Roux-en Y Gastric Bypass (LPRYGB) meaning a Roux-en-Y with a long pouch and a 100 cm alimentary limb to avoid EBAR, with a long biliopancreatic limb to increase metabolic effects.

Methods: A total of 300 LPRYGB cases in a four-year period, with a 90% follow up rate, were analyzed. Anthropometric, technical feasibility, morbidity, weight loss and comorbidity outcomes were analyzed.

Results: The percentage total weight loss (%TWL) was 30.5% at 4 years of follow up (32.3% in primary and 28.3% in revisions). Six intra-operative (2%) and 28 post-operative complications (9.3%) were seen. Out of this 28 complications 11 (3.6%) were late complications. Reoperations were performed in 15 patients (5.0%). Clinically relevant EBAR was present in 3 cases only (1%) 4 years after the operation.

Conclusions: The LPRYGB combines the main advantages of the OAGB (light restriction and moderate malabsorption) with the anti-reflux effect from the Roux-en-Y diversion.
