[Emergency surgery of complicated gastroduodenal ulcers: risk factors and results].

Between 1972 and 1981, 290 patients underwent emergency surgery in this Department for hemorrhagic (n = 104) or perforated (n = 186) gastric or duodenal ulcer. The introduction of cimetidine in 1977 did not influence the annual number of operations for complicated ulcer. Operative mortality was 15% for haemorrhage and 11% for perforation.
