Single-Stage Stapled Conversion of Gastric Bypass to Sleeve Gastrectomy
Exploring the Efficacy of Single Stage Stapled Conversion of Gastric Bypass to Sleeve Gastrectomy, More Leak?
Source: ClinicalTrials.gov · Last updated 3 Nov 2026
Brief summary (registry, in English)
Some patients who have had a gastric bypass (Roux-en-Y gastric bypass or one anastomosis gastric bypass) develop long-term problems such as nutritional deficiencies, intractable dumping syndrome, retrograde intussusception or weight regain, and some cannot afford the lifelong vitamin supplements the bypass requires. When these problems do not respond to non-surgical treatment, the bypass can be reversed to normal anatomy, but many patients refuse reversal because they fear regaining weight. Converting the bypass to a sleeve gastrectomy is an alternative that restores food passage through the duodenum while keeping a restrictive operation. This single-arm study evaluates the efficacy, safety and patient outcomes of single-stage laparoscopic stapled conversion of gastric bypass to sleeve gastrectomy in adults at Kasr Al-Ainy hospitals, Cairo University. Patients are followed for 6 months after surgery for nutritional status, weight regain, quality of life, reflux (GERD) symptoms and postoperative complications, including leak.
