Survival after vagotomy: results of the Aarhus County Vagotomy Trial

In order to investigate whether the previously found excess mortality in surgically-treated patients with peptic ulcer might be due partly to the resections employed, a survival analysis was undertaken in 824 patients 8-13 years after different types of vagotomy. These patients had been submitted to selective gastric vagotomy with drainage, selective gastric vagotomy with antrectomy or parietal cell vagotomy with or without drainage for duodenal ulcer, pyloric ulcer, prepyloric ulcer, or combined ulceration during the period from 1972 to 1977. A statistically significant excessive mortality was found for both sexes in the total material compared to the background population. Analysis of the material, subdivided according to the operative methods employed, revealed a significant excess mortality in men treated with selective gastric vagotomy and antrectomy, whereas the mortality rates were slightly and insignificantly raised in the nonantrectomy groups. No significant difference in the mortality could be demonstrated in relation to the site of the ulcers. Analysis of the cause-specific mortality revealed a significantly raised mortality from gastrointestinal diseases, including a significant excessive mortality in the subgroups of benign peptic ulcer and cirrhosis of the liver. Likewise, the death rate from accidents including the subgroup of suicide was significantly increased. The overall mortality from malignancies was insignificantly raised among patients, whereas cancer in the stomach was significantly increased. An increased mortality from cancer in the lungs and pancreas did not reach statistical significance. These findings are in reasonable accordance with other studies. A significantly increased mortality from gastric cancer has been usual, although not a constant finding after gastric resection.(ABSTRACT TRUNCATED AT 250 WORDS)
