Treatment results of postoperative peritonitis (PP) in 89 patients have been analyzed. All repeated laparoscopy interventions in early postoperative period both after laparoscopic and conventional laparotomy interventions are combined under term "re-laparoscopy". The patients were divided into two groups depending on a kind of repeated operative intervention. The 1st group formed 62 (69.7%) patients with PP sustained relaparotomy in postoperative period. The 2nd main group joined 27 (30.3%) patients experienced beginning interventions with video endoscopy study. Repeated laparoscopy intervention in PP allowed diagnosing a postoperative intraabdominal complication in 85.4% patients, 55.2% of them avoided laparotomy due to application of laparoscopy methods, 30% of them avoided relaparotomy. Indices of lethality in patients underwent laparoscopy (3 of 27 patients died) were reliably lower compared (χ2= 8.62, df=1, р=0.003) to patients in control group (43 of 62 patients died); the result was determined with an earlier low invasive intervention as well as by lower level of its surgical aggression.
