Gastric Bypass with Long Pouch and Transit Bipartition for Endoscopic Access to the Remaining Stomach

Introduction: obesity has a complex and multifactorial etiology, difficult treatment and increasing incidence rates in recent decades. The treatment involves clinical and pharmacological approaches and, in case of lack of results, surgical interventions. Roux-en-Y gastric bypass (RYGB) is one of these surgical interventions in which the stomach is divided, creating a small pouch, and the remaining portion of the stomach become excluded and left without endoscopic access. Objective: to evaluate the results of modified RYGB with long pouch and endoscopic access to the remaining stomach. Materials and Methods: prospective clinical trial with sample selected among patients seen at the Alberto Rassi General State Hospital of Goiânia (HGG) and indicated for bariatric and metabolic surgery confirmed by the medical and multidisciplinary team. The study was conducted from January 2020 to August 2021. Clinical history and laboratory test results of the selected patients were collected through consultations with the medical and multidisciplinary team. Results: twelve participants were included in the study. Of these, 11 (91.7%) were women and the mean age was 46.3 years. The weight before surgery was 112.17 kg (92.00 - 150.00) and the Body Mass Index (BMI) was 44.89 (35.06 - 74.39). After 18 months of surgery, the mean weight was 80.77 kg (±11.92) and the mean BMI was 29.46 (±11.00), showing a significant reduction in both (p = 0.003 and p = 0.002, respectively). All patients underwent endoscopic evaluation of the pouch, remaining stomach and duodenum at 12 months postoperatively. The mean percentage of lost excess weight loss was 68.21%. Conclusion: We conclude that the proposed changes in RYGB (GBLP + GIB – Roux-en-Y gastric bypass with long pouch and gastrointestinal bipartition) did not compromise weight loss or control of type 2 diabetes and other comorbidities and proved to be a safe and effective alternative without gastroduodenal exclusion, enabling a better postoperative follow-up.
