Randomized trial of elective highly selective or truncal vagotomy in chronic duodenal ulceration.
Between 1973 and 1976, 153 patients (124 men, 29 women) with uncomplicated, chronic, duodenal ulcer were entered into a prospective randomized trial of highly selective vagotomy (HSV) or truncal vagotomy and pyloroplasty (TVP). The study was conducted in four Manchester hospitals and the operations were performed by consultants or chief registrars. The follow-up was conducted by personal interview using a standardized questionnaire. The medical gastroenterologist did not know which type of operation the patient had had. The patients who had symptoms were referred back to the surgeon who performed the operation. The clinical laboratory and follow-up data were analysed by computer. There were no operative deaths. Three patients died from unrelated causes, 13 were lost to follow-up; 137 (89.5%) were followed up for a mean of 4.1 years (range from 2.5 to 5.5 years). A modified Visick grading was used to assess the results of surgery. The outcome was good in 82% after TVP and 73% after HSV. This difference and those in the incidences of early or late postprandial dumping, bilious vomiting, weight loss, anemia and heartburn were not significant. Diarrhea was more frequent after TVP (13.4%) than after HSV (1.4%); although the difference was significant (p less than 0.025), this complaint did not present a serious clinical problem. Ulcers recurred in 15 (21.4%) patients following HSV and in 5 (7.5%) after TVP; this difference was statistically significant (p less than 0.05).
