Billroth-II modified with hinged anti-peristaltic afferent loop versus Roux-en-Y reconstruction after distal gastrectomy for gastric cancer: A propensity-score match analysis

Abstract

BackgroundThis study aimed to evaluate the effectiveness of modified Billroth-II with a hinged anti-peristaltic afferent loop by comparing it with the Roux-en-Y method. MethodsWe retrospectively analyzed 344 patients with gastric cancer who underwent distal gastrectomy between 2016 and 2021. Propensity score matching was conducted to balance baseline characteristics. ResultsAfter propensity score matching, there were 117 patients in each group. The Billroth-II group was significantly better regarding operating time (184.7 vs 225.3 minutes), postoperative hospital stays (7.9 vs 9.2 days), and time to semi-solid diet tolerance (2.8 vs 3.8 days). The Billroth-II group demonstrated comparable results with the Roux-en-Y group in weight loss, hemoglobin changes, reflux esophagitis, food residue, and gastritis severity. Presentation of bile in gastric remnant was significantly higher in the Billroth-II group (42.9% vs 10.3%). ConclusionThere were no significant differences in functional outcomes between Billroth-II and Roux-en-Y reconstructions. The Billroth-II was superior to Roux-en-Y in operating time, hospital stays, and time to semi-solid diet tolerance. The Billroth-II could be considered an acceptable alternative reconstruction after distal gastrectomy.
