Comparative study of outcomes of Roux-en-Y reconstruction and Billroth Ⅰ reconstruction performed after radical distal gastrectomy

Summary: Background: Billroth Ⅰ (BⅠ) reconstruction and Roux-en-Y (RY) reconstruction are both commonly performed after distal gastrectomy (DG). We conducted a retrospective study to evaluate which is the better option. Methods: Included in our study were 162 patients who, between April 2011 and October 2015, underwent DG followed by BⅠ reconstruction (n = 93) or RY reconstruction (n = 69). All patients were followed up for at least 1 year. We compared perioperative outcomes, postoperative complications, gastrointestinal (GI) symptoms, endoscopic findings, and nutritional status between the 2 groups of patients. Results: Patient characteristics did not differ between the 2 groups, with the exception of the incidence of gastric body tumors, which was significantly higher in the RY group (73.9% vs. 19.4%; p
