[Intestinal ischemia after surgery of the infrarenal aorta. Apropos of 13 cases].
Ischemic damage of the gastrointestinal tract following aorto-iliac surgery was estimated in a retrospective study. Between 1984 and 1988, we observed 13 cases of intestinal ischemia from a total of 416 surgical patients (3 per cent): 7 cases of full-thickness necrosis and 6 cases of transient ischemia. They represent 23 per cent of complications in ruptured aneurysmal surgery, 2.8 per cent in elective aneurysmal surgery, and 1.6 per cent in operations for obstructive lesions. All deaths (5/13) followed necrosis. Diarrhea, sometimes bloody, was the main symptom. Its sensitivity was 70 per cent, and its specificity was 98 per cent. Leukocytosis (greater than 10000/mm3), was noted in 70 p. cent of the cases of ischemia. The diagnosis was established by colonoscopy in 7 cases and by surgical examinations in 6 cases. The endoscopic injuries were ulcerations, punctate hemorrhages, and pseudomembranes localized in the sigmoid (77 p. cent), left colon (38 per cent) and small bowel (15 per cent). Of 13 patients, 6 developed intraoperative hypotension. This study confirms the gravity of intestinal ischemia after aortic surgery. In high risk patients (ruptured aortic aneurysm, intraoperative hypotension, postoperative diarrhea) endoscopy offers the possibility of early diagnosis and appropriate treatment.
