[Perforated gastric and duodenal ulcer (635 cases) (author's transl)].

Perforation could be observed in 10.14% of all patients with gastroduodenal ulcer admitted to our clinic from 1946 to 1976. 23.16% of these patients were older than 61 years, whereas 15.9% were younger than 30 years. 91.18% had typical symptoms of perforation, symptomless were 6.93%. 1.81% arrived moribund in the hospital. During the last 30 years as a rule the perforation was only sutured, primary resection was being performed only in rare cases. Nowadays, in cases of perforated duodenal ulcer we add vagotomy plus pyloroplasty to the suture. The total mortality rate came up to 22%, with a significant decrease from 1946 to 1975.
