Thirty cases of uncomplicated duodenal ulcer treated by anterior superficial lesser curvature seromyotomy and posterior truncal vagotomy were studied to evaluate the efficacy of this procedure. There was completeness of vagotomy in all the cases as shown by endoscopic Congo Red test. Twenty-seven cases were asymptomatic at 1-48 months (Mean 22.3) follow up, while 3 patients had controllable side effects such as dumping and diarrhoea. There was no mortality. This procedure is safe, effective and is a favourable alternative to highly selective vagotomy.
