[Vagotomy in emergency surgery for duodenal ulcer].

We examined acid-producing stomach functions, local hemodynamics and motility of the stomach and duodenum in performing organ preservation surgery: combined gastric vagotomy, selective proximal vagotomy and extended selective proximal vagotomy. Changes of hemodynamics and motility in the early postoperative period are related to the technical peculiarities of performing various types of vagotomy. Restoration of the functional state of the stomach and duodenum takes place in the late postoperative period. The acid-producing function in the late postoperative period is reduced to the safe level concerning ulceration, irrespective of the vagotomy type.
