[Perforative gastroduodenal ulcers].

Treatment results of 986 patients with perforative gastroduodenal ulcers were analyzed. The sequence of surgeon's acts was diagnostically effective in 99.5%. 776 (78.7%) of patients presented with duodenal ulcer; 210 (21.3%) had gastric ulcer. Ulcer closure was performed in 934 (94.7%) cases; gastric resection was made in 52 (5.3%) cases. Postoperative lethality rate was 4.3%. Tissue destruction proved to be partly connected with the level of the connective tissue metabolites in blood. The balance of factors of aggression and defense (Helicobacter invasion, level of mucus formation, mucosal leucocytal infiltration, acid level in stomach and level of necrosis factor in blood) was registered in long-term follow-up in dependence of the operation performed. Ulcer perforation recurrence was registered in 18.8% of simple closure cases and in 3.8% of patients after gastric resection.
