Objective. To evaluate postoperative complications using the modified Slavien–Dindo scale in elderly and senile patients with acute peritonitis.
Materials and methods. The results of treatment of 145 patients with gastric and duodenal ulcer complicated by perforation were analysed. The modified Slavien–Dindo scale (2004, 2009) was used to assess postoperative complications.
Results. The analysis of the results of treatment of elderly and senile patients with acute peritonitis showed that a significant proportion of them had postoperative complications – 76 (52.4%): 53 (36.6%) had non–surgical complications, 23 (15.9%) – surgical complications (p = 0.00027).
Conclusions. The Slavien–Dindo scale makes it possible to establish the presence of postoperative complications, but does not allow to find out why they occurred and prevent them. Assessment of postoperative complications using the modified Slavien–Dindo scale is possible only for analysis for the purpose of collecting statistical data, but it cannot be used in general clinical practice to analyse the quality of treatment of elderly and senile patients with acute peritonitis.
