Remnant Gastrectomy and Gastric Bypass: A Systematic Review of Indications and Outcomes of Resectional Gastric Bypass. Obes Surg 2024; 34:2634-2649. [PMID: 38735966 DOI: 10.1007/s11695-024-07240-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/13/2024] [Revised: 04/09/2024] [Accepted: 04/16/2024] [Indexed: 05/14/2024]
Abstract
BACKGROUND In this systematic review, we aim to evaluate the reasons and outcomes behind remnant gastrectomy with or after gastric bypass procedures. RESULTS A total of 66 studies examining 1918 patients were included in this study with 70% of female predominance. Twenty studies reported RGB on 1751 patients and 46 studies reported remnant gastrectomy after gastric bypass in 167 patients. The most common etiology of RGB was related to the in situ remnant stomach neoplasia in 10 studies on 981 patients; mostly for preventive intentions in high prevalence areas. Remnant gastrectomy after gastric bypass was performed to treat a complication such as GGF, retrograde bile reflux gastritis, cancer mostly adenocarcinoma. Studies revealed that RGB has similar weight loss in comparison to standard Roux-en-Y gastric bypass.

Kumbhari V, le Roux CW, Cohen RV. Endoscopic Evaluation and Management of Late Complications After Bariatric Surgery: a Narrative Review. Obes Surg 2021; 31:4624-4633. [PMID: 34331187 DOI: 10.1007/s11695-021-05603-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/07/2021] [Revised: 07/09/2021] [Accepted: 07/14/2021] [Indexed: 10/20/2022]
Abstract
Despite ongoing evolution in technique and a low mortality rate, clinicians may care for patients who suffer late complications (> 90 days of surgery) after bariatric surgery. Endoscopic techniques are used to identify and manage many of the late complications of the two most commonly performed bariatric surgeries: sleeve gastrectomy and Roux-en-Y gastric bypass. Stenosis at the incisura angularis and gastroesophageal reflux disease may occur in patients who have undergone a sleeve gastrectomy. Patients who underwent a Roux-en-Y gastric bypass can suffer marginal ulceration, gastrojejunal anastomotic stricture, and gastro-gastric fistula. Clinicians may also encounter biliary pathologies such as choledocholithiasis, chronic abdominal pain, and weight regain. This narrative review provides an update on the endoscopic evaluation and management of patients with late complications after sleeve gastrectomy or Roux-en-Y gastric bypass.

Ulcer Disease in the Excluded Segments after Roux-en-Y Gastric Bypass: a Current Review of the Literature. Obes Surg 2020; 31:1280-1289. [PMID: 33230760 PMCID: PMC7921036 DOI: 10.1007/s11695-020-05123-w] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/16/2020] [Revised: 11/10/2020] [Accepted: 11/11/2020] [Indexed: 02/08/2023]
Abstract
Ulcer disease in excluded segments after Roux-Y gastric bypass (RYGB) is rare but can evolve into a life-threatening situation. The excluded segments exhibit a different behavior from that of non-altered anatomy; perforated ulcers do not result in pneumoperitoneum or free fluid, and therefore must be met with a low threshold for surgical exploration. The anatomical changes after RYGB impede routine access to the remnant stomach and duodenum. There are various options to address bleeding or perforated ulcers. While oversewing and drainage preserves the anatomy and forgoes resection, remnant gastrectomy offers a definitive solution. The importance of traditional risk factors such as smoking or use of non-steroidal anti-inflammatory drugs is unclear. Eradication of Helicobacter pylori and secondary prophylaxis with proton-pump inhibitors is advisable, albeit in double-dose.
