Weight loss and malnutrition after conversion of the primary Roux-en-Y gastric bypass to distal gastric bypass in patients with morbid obesity

Background After Roux-en-Y gastric bypass (RYGB), 15% to 35% of patients fail to lose sufficient weight. Distalization of the limbs of the RYGB (D-RYGB) with shortening of the common channel (CC), has been used to induce additional weight loss. However, this may increase the risk of malnutrition. Objective The aim of this study was to assess postoperative outcomes after D-RYGB with an alimentary limb of 250 to 300 cm and CC of 100 cm. Setting...
