The Stability of the Insulin Test Result after Truncal Vagotomy and Drainage for Duodenal Ulcer

Abstract

The stability of the fasting, spontaneous and insulin-activated gastric acid secretion was investigated by comparing insulin test results 10 days after truncal vagotomy and drainage for duodenal ulcer, with test results 3–4 years later in 320 patients. The late performance was not based upon the clinical status, but was achieved by routine. Small, but significant changes occurred in fasting and activated secretions in patients without recurrence. while recurrence was associated with a clear increase of the activated secretion before reoperation. The value of the test in predicting recurrence was not better at the follow-up than on the 10th postoperative day.
