Abstract

The optimal size of Gastrojejunostomy (GJ) in Laparoscopic Roux-EnY Gastric Bypass (LRYGB) for a- preferential weight loss is still unknown. This study aimed to investigate the influence of linear-stapled GJ size in long-term LRYGB weight reduction results. We performed a retrospective analysis of 100 patients who underwent LRYGB surgery between January and July 2021. The patients were divided into two 50-patient groups based on the size of their linear-stapled GJ, either 30 or 45 mm. Their weight loss was observed and compared on day 15, and the following appointments were 1, 3, 6, 9, 12, 18, and 24 months after surgery. After 24 months, the 30-mm group reduced their BMI by an average of 19.23, compared with the 16.43 kg/m² of the 45-mm group (p < .001). Overall, repeated measures ANOVA showed a beneficial weight loss pattern for the 30-mm group in all four categories (weight, BMI, EWL, and TWL). Upon adjusting for age, biliopancreatic length, alimentary length, sex, history of diabetes, and a history of hypertension in repeated measures ANOVA, this difference remained significantly in favour of the 30-mm GJ. Based on the results of this study, performing a gastrojejunostomy with a 30-mm stapler compared to a 45-mm stapler increases weight loss in LRYGB patients.

造口越紧，减重越大：狭窄的胃空肠造口对roux-en-Y胃旁路术后的减重更有利。

在腹腔镜Roux-EnY胃旁路术（LRYGB）中，胃空肠造口术（GJ）的最佳尺寸仍不清楚。本研究旨在探讨线性钉钉GJ尺寸对LRYGB长期减重效果的影响。我们对2021年1月至7月间接受LRYGB手术的100例患者进行了回顾性分析。将患者分为两组，每组50名患者，分别为30 mm和45 mm。在术后第15天观察和比较体重减轻情况，并在术后第1、3、6、9、12、18和24个月进行随访。24个月后，30毫米组的BMI平均下降了19.23，而45毫米组的BMI平均下降了16.43 kg/m2
