Abstract
BACKGROUND: Colonic ischaemia is a well documented complication of abdominal aortic reconstruction. In this prospective study patients had routine preoperative and postoperative colonoscopy and biopsy, in order to determine the true incidence and implications. METHODS: Fifty-six patients undergoing elective infrarenal aortic surgery, 28 for aneurysm and 28 for occlusive disease, had colonoscopy and biopsy before and 1 week after operation. RESULTS: Colonic ischaemia was identified histologically in biopsies from 16 (30 per cent) of 53 patients. Almost half the patients had normal macroscopic appearances. Two factors exhibited a statistically significant association with the development of ischaemia: prolonged cross-clamp time (P < 0.05) and postoperative diarrhoea (P< 0.001). Co-morbidity was much higher in patients with colonic ischaemia (P< 0.005). Overall morbidity was significantly greater in the aneurysm group (P < 0.05). CONCLUSION: Colonic ischaemia is common after aortic reconstruction. When suspected, colonoscopy with biopsy is diagnostic.
