Proximal gastrectomy reconstructed by jejunal pouch interposition for upper third gastric cancer: Prospective randomized study

Proximal gastrectomy with jejunal pouch interposition (PGJP) has been advocated as an alternative operation for upper third gastric cancer. However, there has been no prospective randomized trial comparing PGJP with total gastrectomy with Roux-en-Y esophagojejunostomy (TGRY). The aim of this study was to compare the short- and medium-term results of PGJP and TGRY in a randomized clinical trial. Fifty-one patients with upper third gastric cancer were randomized to either PGJP (n = 25) or TGRY (n = 26). Outcome measures were postoperative complications, nutritional status assessed by serum nutritional parameters, and postgastrectomy symptoms. There were no significant differences in operating time, hospital stay, and postoperative complications. Blood loss was significantly less in the PGJP group (P = 0.036). Nineteen patients (73%) in the TGRY group had one or more postgastrectomy symptoms, which was significantly more frequent than in the PGJP group (32%; P = 0.012). There were also significant differences between the two groups with regard to food intake, weight recovery, hemoglobin, and serum vitamin B-12 levels in favor of PGJP. In conclusion, proximal gastrectomy with jejunal pouch interposition for upper third gastric cancer is safe, and is associated with a greater reduction in postgastrectomy symptoms and better nutritional status compared with conventional total gastrectomy.
