[Acute peptic lesions of the gastroduodenal mucosa in patients with obstructive jaundice].

Complex study of the gastric acid-producing activity, the condition of the gastroduodenal mucosa, and the serum gastrin concentration in 80 patients with obstructive jaundice showed that the appearance of acute erosive-ulcerative injuries of the mucosa of the gastroduodenal zone depended on the increase of activity of the peptic factor of the gastric medium. Peptic complications occurred in 27.1% of patients with initial normo and hyperacidity and a high level of blood gastrin. The absence of bile in the duodenum (obstructive jaundice, by-pass biliodigestive anastomoses) stimulated the peptic factor. This is evidently linked with secretin deficiency (absence of the effect of bile on the secretin producing S-cells) leading to weakened inhibiting effect of secretin on the serum gastrin content, which results in hypergastrinemia and hyperacidity.
