Anterior lesser curve seromyotomy with posterior truncal vagotomy versus proximal gastric vagotomy: results of a prospective randomized trial 3-8 years after surgery.

Abstract

In a prospective randomized trial, anterior lesser curve seromytomy with posterior truncal vagotomy (ASPTV, n = 50) was compared with proximal gastric vagotomy (PGV, n = 50). Most of our patients were young men with ASA grade I risk, and 80% were expatriates. They were followed up for 3 to 8 years after surgery. The mean reductions of basal acid output (BAO) and insulin-stimulated peak acid output (IPAO) were 85% and 88%, respectively, soon after surgery for both ASPTV and PGV groups. These values remained at 70% and 60% of their preoperative level for 1 year. Good to excellent results (Visick I and II) were recorded in 76% of cases in both groups. The recurrent ulcer rate was 14% for PGV and 12% for ASPTV. This trial suggests that for the treatment of duodenal ulcer ASPTV is as good an operation as PGV.
