Laparoscopic antiperistaltic versus isoperistaltic gastrojejunostomy for palliation of gastric outlet obstruction in advanced cancer.

The purpose of the study was to compare the impact of the peristaltic orientation of laparoscopic gastrojejunal anastomoses (LGJ) in patients with malignant gastric outlet obstruction (GOO) on postoperative delayed-return gastric emptying (DRGE) rates. GOO was defined as complete holdup of contrast at barium meal and/or failure of gastroscope to pass beyond stricture. DRGE was defined as inability to eat regular diet by day 10. Thirty-four patients undergoing antiperistaltic LGJ were compared with 21 patients undergoing isoperistaltic LGJ at two institutions during the same period. Thirty-day mortality was 5.4%, and median survival was 6.2 months. Thirty-day morbidity was 20%, and conversion rate was 3.6%. DRGE rates were increased after isoperistaltic LGJ (0 vs. 3; P < 0.05), but patient groups were not well matched for type of primary cancer (P < 0.05). All patients with DRGE resumed food intake 12 to 16 days after surgery. There were 21 admissions before death, with a reoperation rate of 11.5% and a recurrent GOO rate of 3.8%. Although no conclusions could be drawn about whether the peristaltic orientation of the anastomosis had a bearing on DRGE rates, LGJ resulted in an overall 6% rate of DRGE.
