BackgroundThe main advantage of the Roux-en-Y (RY) operation is that it prevents bile and pancreatic juice from reaching the gastric mucosa, although the gastrojejunostomy may cause functional delayed gastric emptying (DGE), known as RY stasis syndrome. Rho-shaped Roux-en-Y reconstruction (rRY), an RY reconstruction with a rho-shaped anastomosis, is an established operation that has been found to be effective in preventing DGE.MethodsWe conducted the randomized trial of RY versus rRY reconstruction after gastric cancer resection. The primary endpoint was the frequency of DGE, and secondary endpoints were the length of postoperative hospital stay, morbidity, and nutritional status. Seventy patients were enrolled, with 35 in each group.ResultsThe incidences of postoperative mortality and morbidity did not differ significantly between the two groups. There were no significant differences in nutritional status between the two groups after discharge. Delayed gastric emptying occurred in two patients (6%) in the RY group and four patients (11%) in the rRY group (P = 0.67). Logistic regression analysis revealed that truncal vagotomy was significantly associated with DGE inhibition.ConclusionsOur findings showed that RY reconstruction after gastrectomy may be as simple and sufficient as conventional reconstruction.
