Colonic ischemia following surgery for sigmoid colon and rectal cancer: a study of 10 cases and a review of the literature

Abstract

Purpose: Colonic ischemia following colorectal surgery is an unusual and serious complication. As it has been reported that the incidence of colonic ischemia was higher after laparoscopic surgery, the aim of this report was to document the clinical features of postoperative colonic ischemia following colorectal surgery.

Methods: Among 1,201 surgeries for sigmoid colon and rectal cancer by a single surgeon from 2006 to 2010, 10 cases of postoperative colonic ischemia were retrospectively identified (0.83%). IMA high ligation was routinely made in all surgeries. The clinical findings and laboratory data of these 10 cases were evaluated.

Results: Of the 10 patients, 9 were male and 1 was female. The mean age was 66.9 years old. The mean BMI was 23.3. Three patients (30%) had a cardiovascular disease other than hypertension. Eight patients (80%) underwent laparoscopic surgery and two patients (20%) underwent open surgery. Intraoperative bleeding occurred in five patients (50%, mean 435 ml). The average day for occurrence of postoperative colonic ischemia was on the 5th day (range 2nd-10th day). A consistent postoperative fever was found in eight patients (80%). Mortality due to postoperative colonic ischemia was 10%.

Conclusions: Postoperative colonic ischemia may be considered one of the more important complications of colorectal resection.
