In this systematic review, we aim to evaluate the reasons and outcomes behind remnant gastrectomy with or after gastric bypass procedures.
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.
在本次系统综述中，我们旨在评估胃旁路手术后或之后行残胃切除术的原因和结果。
共有 66 项研究纳入了 1918 例患者，其中女性占 70%。20 项研究报告了 1751 例患者的 RGB，46 项研究报告了 167 例患者胃旁路术后的残胃切除术。导致 RGB 的最常见病因与原位残胃肿瘤有关，在 10 项涉及 981 例患者的研究中，这主要是出于高发病地区的预防目的。胃旁路术后行残胃切除术主要是为了治疗胃轻瘫、胆汁反流性胃炎、癌症（主要是腺癌）等并发症。研究表明，与标准 Roux-en-Y 胃旁路术相比，RGB 的减重效果相似。
