Brief Summary

There are Billroth-I, Billroth-II, Billroth-II with Braun, and Roux-en-Y reconstruction after distal gastrectomy.

Hypothesis: Billroth-II modified method is non-inferior to Roux-en-Y method in terms of reducing reflux esophagitis after distal gastrectomy for gastric cancer patients.

Detailed Description

Since the first gastrectomy by Theodore Billroth in 1881, this procedure remained a curative treatment for gastric cancer. Reconstruction method after gastrectomy may affect complication rates, post-operative nutritional status, and quality of life (QoL). There are several reconstruction methods for distal gastrectomy, including Billroth I (B-I), Billroth II (B-II), Roux-en-Y (R-Y). B-I and B-II were considered better than R-Y in terms of shorten operation time and lessen blood loss due to technical simplicity. In contrast, R-Y was better in terms of preventing bile reflux and remnant gastritis, which can increase remnant stomach cancer and worsen QoL. However, long term QoL was similar between B-I and R-Y in some randomized controlled trials. Although bile reflux was higher in B-I and B-II groups, remnant gastric cancer was similar between 3 groups in this study. In brief, which one is the ideal reconstruction after distal gastrectomy is still controversial.

At our center, reconstruction after distal and sub-total gastrectomy including B-I, B-II, B-II with Braun anastomosis, and R-Y, depended mostly on surgeons' preferences. From 2018, to decrease bile reflux rate while not increasing operation time, we applied modified B-II technique with 3-5 sutures between the afferent loop to the gastric remnant. This study was conducted to evaluate the efficacy of this method by comparing it with the R-Y method.

Arm && Interventions
GroupInterventionDescription
Roux-en-YDistal gastrectomyJejunum will be transected 25 to 30 cm from Treitz's ligament. Marginal vessels will be transected if needed to make sure the loop will reach the stomach without tension. Isoperistaltic gastrojejunostomy will be made at posterior wall of the stomach. After checking for bleeding, common entry hole will be closed using running suture. Jejunojejunal mesenteric defect and Petersen's defect will be closed.
Billroth-II modifiedDistal gastrectomyAn opening will be made at jejunum 25 cm from Treitz's ligament. Another at greater curvature of the stomach right above transected line. A straight stapling device will be used to make isoperistaltic anastomosis at posterior wall of the stomach. After checking for bleeding, common entry hole will be closed using running suture and 3 -5 sutures to attach afferent loop to the remnant stomach
