Laparoscopic Roux-en-Y gastric bypass (RYGB) is crucial for significant weight reduction and treating obesity-related issues. However, the impact of gastrojejunostomy (GJ) anastomosis diameter on weight loss remains unclear. We investigate this influence on post-RYGB weight loss outcomes. A systematic search was conducted. Six studies met the inclusion criteria, showing varied GJ diameters and follow-up durations (1-5 years). Smaller GJ diameters generally correlated with greater short-to-medium-term weight loss, with a threshold beyond which complications like stenosis increased. Studies had moderate-to-low bias risk, emphasizing the need for precise GJ area quantification post-operation. This review highlights a negative association between smaller GJ diameters and post-RYGB weight loss, advocating for standardized measurement techniques. Future research should explore intra-operative and AI-driven methods for optimizing GJ diameter determination.
腹腔镜 Roux-en-Y 胃旁路术（RYGB）对于显著减轻体重和治疗肥胖相关问题至关重要。然而，胃空肠吻合术（GJ）吻合口直径对减重的影响尚不清楚。我们研究了这种影响对 RYGB 后减重效果的影响。进行了系统检索。六项研究符合纳入标准，显示了不同的 GJ 直径和随访时间（1-5 年）。较小的 GJ 直径通常与更大的短期到中期减重相关，超过一定阈值后，狭窄等并发症会增加。研究存在中低偏倚风险，强调了术后需要对 GJ 区域进行精确量化。本综述强调了较小的 GJ 直径与 RYGB 后体重减轻之间的负相关关系，提倡使用标准化的测量技术。未来的研究应探索术中及 AI 驱动方法，以优化 GJ 直径的确定。
