Intestinal infarction: report of 98 cases.

The Authors conducted a retrospective study on 98 patients with intestinal infarction observed from 1987 to 1999 in the Emergency Care Unit of the Loreto Hospital, Naples. In our hospital there are over 20,000 admissions, 3,900 of whom in the Emergency Care Unit. Intestinal infarction accounts for 0.049% of all admissions and 0.45% of emergency surgery admissions. About 500 laparotomies are performed annually, 1% of which for intestinal infarction. All patients in this series were operated on within 10 hours of admission. The following procedures were performed: 31 jejuno-ileal resections; 26 right hemicolectomies associated with small intestine resection; 5 upper mesenteric artery embolectomies plus wide gut resections (3 also underwent second-look operations within 36 hours of the initial surgery with further gut resection); 1 Hartmann's and 5 Volkmann's operations (all of these patients had colonic gangrene); 30 (30.5%) underwent exploratory laparotomy due to massive infarction. The prognosis of intestinal infarction is still ominous. Our mortality rate is 68%. Both clinical and laboratory data are non-specific and delayed diagnosis is the main cause of this mortality rate. Abdominal CT is an accurate and sensitive diagnostic tool. TPN enables us to achieve good nutritional support even for wider resections.
