The role of obstructive resection in the treatment of acute intestinal obstruction complicated by bowel necrosis

Abstract

Methods of surgical intervention in acute intestinal obstruction with necrosis of the strangulated area of the intestine are the subject of ongoing discussions. There is no doubt that every patient with this disease should undergo emergency surgery. However, diagnosing necrosis of the strangulated area is not easy. For this reason, a number of authors recommend refraining from emergency surgery for all patients with intestinal obstruction during dynamic follow-up, which can last up to 14 days. Over the past century, the etiology of intestinal obstruction has shifted from strangulated hernia to postoperative adhesive disease, which has led to a paradigm shift in methodological approaches. In order to successfully manage acute intestinal obstruction with suspected strangulation, the clinician today must be able to distinguish between patients requiring urgent surgery and those who should receive conservative therapy.In this paper, we consider the surgical approach of delayed anastomosis formation on significant clinical material, including tactical approaches, timing and necessary conditions for anastomosis formation in patients with intestinal obstruction complicated by necrosis of the strangulated area.The complex of therapeutic measures in the treatment of patients with acute intestinal obstruction complicated by necrosis of the strangulated area of the intestine, intraoperative perforation of the intestine during separation of adhesions, both in conditions of peritonitis and without it, should include obstructive resection of the intestine in combination with the formation of an anastomosis in a delayed order, as well as or planned sanitation of the abdominal cavity. All this makes it possible to reduce the incidence of interintestinal anastomosis failure from 86.7 to 0.96% of cases, and postoperative mortality from 41.8 to 14.4%.
