[The gastrin-producing function of the stomach and intestinal digestion in patients with peptic ulcer].

Assessment of serum gastrin, digestion and absorption of protein, fat 10-15 days after operative treatment in 119 patients with gastric ulcer revealed that independent of the observation time the gastrin level remains low in patients following gastric resection and high following selective proximal vagotomy. The processes of digestion and absorption of proteins, fats are inhibited in the early period after operative intervention with a tendency towards normalization in the remote period.
