title: Gastrinemia, serum minerals and calciotropic hormones following highly selective vagotomy in duodenal ulcer patients. Results of a 1-year study.
abstract: Duodenal ulcer patients with normal (n = 36) or increased (n = 24) gastric acid production during maximal pentagastrin stimulation, were examined preoperatively and at different intervals (up to 1 year) after highly selective vagotomy (HSV). Fasting levels of gastrin, parathormone, calcitonin, proteins, calcium and magnesium fractions, inorganic phosphate and alkaline phosphatase were determined in serum, those of glucagon in plasma. Both types of patients have the same gastrin levels preoperatively (approx. 36 pg-equiv./ml). Magnesium and alkaline phosphatase are significantly higher in patients with a normal secretory response than in those with hypersecretion. The postoperative gastrin increase is significantly higher in the former than in the latter, while postoperative glucagon levels drop in both groups. The analysis of calcium fractions and the dissociation constant did not show any HSV-mediated change in calcium metabolism. The magnesium levels, however, are lower one year after the operation than in the pre-operative period in patients with normosecretion. In this group parathormone and calcitonin remain unchanged while in patients with a hypersecretory response a slight (parathormone) or moderate (calcitonin) tendency towards low values can be recognized in the post-operative period. We conclude that the duodenal ulcer patients probably belong to groups with different pathophysiological behaviour which do not have identical reactions to HSV. Imbalances in the metabolism of minerals and that of related hormones could not be demonstrated up to one year after HSV.
