[Efficacy of hyperselective vagotomy on duodenal ulcer. 284 cases].

Two hundred and eighty-four patients who underwent highly selective vagotomy for duodenal or prepyloric ulcer were followed up for at least 1 year, and 47.9% of them for at least 5 years (mean : 58 months). The actuarial recurrence rates were 4.7% at 3 years, 9.6% at 5 years and 13.1% at 7 years. These results do not agree with the recently published figure of 20%. The authors insist on the necessity to dissect the lower oesophagus on a length of at least 5 cm. In duodenal ulcers, this technical detail should result in a cure rate of about 90% at 5 years.
