Anterior or posterior gastro-jejunostomy with truncal vagotomy for duodenal ulcer--are they functionally different?

ABSTRACT

Truncal vagotomy with gastrojejunostomy (GJ) is the standard treatment for chronic cicatrizing duodenal ulcer with gastric outlet obstruction. We tried to determine if a significant functional difference exists in the early and late outcomes following anterior and posterior types of GJ to treat this condition. The case records of 106 patients who underwent truncal vagotomy and GJ at our institute from 1 January 1995 to 31 December 1999 were studied retrospectively. Patients were followed up with a personal interview. Perioperative and long-term parameters were compared in the anterior and posterior G.I. groups. Sixty-five patients (61.32%) were followed up; 31 in the anterior group and 34 in the posterior group. The median follow-up was 5 years (range 2.5-7.5 years). Except for a significant difference in length of afferent loop (p < 0.0001), there were no significant differences in the duration of hospital stay, nasogastric aspirates on postoperative days 1, 2, 3 and 4 and the day the nasogastric tube was removed. Early postoperative complications were uncommon and not different in the two groups and long-term outcomes were similar. The Anterior GJ, being technically easier and needing less operative time, may be advocated in all cases of chronic duodenal ulcer, with gastric outlet obstruction requiring truncal vagotomy and drainage.
