Results of highly selective vagotomy in a non-university teaching hospital.

Clinical and laboratory results are presented of 229 patients treated by highly selective vagotomy for duodenal ulcer in a non-university teaching hospital. Sixty-two per cent of the operations were performed by residents as part of their training. After 1-8 years follow-up (97 per cent complete) there were 22 recurrences (9.6 per cent). The residents had fewer recurrences than the consultants, but their patients follow-up was shorter. The usual Visick grading is presented (1, 2: 83.5 per cent; 3, 4: 16.5 per cent) as well as an additional way of grading described by Visick in 1948 which suggests that 4 per cent appear to be permanent failures. Mortality rate was 0.4 per cent, complications rate was low and side effects were in general of minor importance. Laboratory results are presented showing that the basal acid output (BAO) was reduced permanently by 65 per cent, and the PAO by 50 per cent. In patients with recurrences BAO was not reduced and the PAO was less reduced than in the non-recurrence group. Metabolic parameters did not deteriorate. Basal serum gastrin rose after operation while serum vitamin B12 remained constant with a minimal tendency to decrease.
