The present study aims to determine the mean duration of the conservative management that can be tolerated by the patients with intestinal obstruction secondary to the postoperative peritoneal adhesions, in order to postpone the surgical intervention. Material and method: The data of the patients with intestinal obstruction secondary to postoperative peritoneal adhesions were retrospectively collected and analysed. The number of readmissions, the type of the therapeutic management, the duration of the conservative treatment, the number of surgical reinterventions and the intraoperative aspect represented the studied variables. Results: 543 patients with intestinal obstruction secondary to postoperative peritoneal adhesions, admitted in the Surgical Department of Sfantul Pantelimon Emergency Hospital from Bucharest, Romania, between January 2014 and July 2018, were enrolled in the study. 233 patients underwent conservative treatment, 310 patients being surgically treated. The mean interval necessary for the monitoring of the patients non- operatively treated was 7 days, within a range of 2 to 14 days. For the surgically treated cases, the mean monitoring interval was 5 days, within a range of 1 to 14 days. Among the patients that underwent surgical treatment, there were 276 cases of adhesiolysis, 31 cases of intestinal resection with anastomosis and 3 cases of intestinal resection with terminal ileo- or colostomy. Conclusion: Under strict monitoring, a signifi cant number of cases of intestinal obstruction secondary to postoperative peritoneal adhesions can, successfully, be treated using conservative management, within 7-10 days.
