[Combined selective proximal vagotomy in the surgical treatment of duodenal ulcer].

Preservation of adequate blood supply to a gastric wall and resistance of mucosa of the gastroduodenal region with simultaneous full-value parasympathetic denervation of its acid-producing zone in performance of selective proximal vagotomy contributes to decrease in incidence and pronouncement of ischemic disorders in motor-evacuatory function of the stomach at the early postoperative period, effective and stable reduction in acid production, shortening of duration of the postoperative treatment and rehabilitation of the patients, prophylaxis of ulcer recurrences.

[Status of the protective mucous barrier of the stomach after organ-sparing operations for duodenal ulcer].

A protective mucous barrier of the stomach was studied in 153 patients with duodenal ulcer disease. Before the operation in 70 patients, decrease in concentration of protective factors of gastric mucus, especially in complicated form of ulcer disease was noted. More complete restoration of a protective barrier was noted after organ-preserving operations with excision of ulcerous substrate (in 54 patients) than after those without its excision (in 29).
