The delta-shaped anastomosis in laparoscopic distal gastrectomy: analysis of the initial 100 consecutive procedures of intracorporeal gastroduodenostomy.

BACKGROUND: We developed a new method of intracorporeal gastroduodenostomy, the delta-shaped anastomosis, in which only endoscopic linear staplers are used. In this report, we present the short- and long-term outcomes of our initial experience with this procedure.
METHODS: We retrospectively analyzed 100 consecutive gastric cancer patients who underwent the delta-shaped anastomosis procedure from May 2001 to November 2006. All of them underwent a laparoscopic distal gastrectomy with regional lymph node dissection. Quality of life was assessed with a questionnaire 6 months or more postoperatively, and the gastric remnant was evaluated by endoscopy one year following the surgery.
RESULTS: Eight surgeons successfully performed the delta-shaped anastomosis without any conversion to laparotomy. The learning curve for all surgeons was steep and the mean time for the anastomosis was 13 min. Only one patient developed an anastomotic leak, and the leak was minor. Sixty-five patients tolerated a 1500 kcal/day soft diet at the time of discharge. The mean follow-up period was 54.9 months. Only one patient reported symptoms indicative of dumping. Two patients were diagnosed with reflux esophagitis, and approximately 70% had evidence of bile reflux, but severe gastritis of the remnant stomach on endoscopy was uncommon.
CONCLUSIONS: The wide lumen of the delta-shaped anastomosis led to early, adequate postoperative oral intake without a significant incidence of dumping syndrome. The delta-shaped anastomosis is safe and simple and provides satisfactory postoperative results.
