A prospective randomized trial of vagotomy in chronic duodenal ulceration: 4-year follow-up.

A total of 153 patients (124 male and 29 female) with uncomplicated chronic duodenal ulceration were studied in a prospective, randomized trial of proximal gastric vagotomy (PGV) and truncal vagotomy and pyloroplasty (TVP), conducted in four Manchester hospitals. Of these, 137 patients have now been followed up for 2.5 to 5.5 (mean 4.1) yr. There have been 15 (21 per cent) recurrent ulcers following PGV compared with 5 (7.5 per cent) after TVP (P less than 0.05). A satisfactory functional result was obtained in 82 per cent of patients after TVP compared with 73 per cent following PGV and there was little difference between the groups with regard to the incidence of dumping, heartburn and vomiting. There was significantly more diarrhoea following TVP (13 per cent) compared to PGV (1.4 per cent) but this represented only a minor clinical problem.
