Abstract

Purpose: This study aimed to correlate multidetector-row computed tomography (MDCT) findings and postoperative prognosis in malignant large-bowel obstructions.

Materials and methods: Twenty-seven patients affected by malignant colonic obstruction underwent MDCT examination and were analysed for obstruction site, colon-wall morphology, intestinal content alterations and transverse diameter of ascending colon.

Results: Obstruction site was recognised in all cases (5/27 ascending colon; 1/27 transverse colon; 11/27 descending colon; 10/27 sigma-rectum). Intestinal content consisted of mainly air in 3/27 patients, mainly fluid in 11/27 and air-fluid levels in 13/27. In 9/27 cases, pneumatosis intestinalis was found. Mean maximum diameter of the ascending colon was 8.2 cm. Overall mortality rate was 37%. An intestinal content mainly consisting of air (3/3 living patients) or fluid (7/11 living patients) were indicative of good prognosis. Air-fluid level detection indicated poor prognosis in 7/13 cases. Pneumatosis intestinalis (7/9 deceased patients) and ascending colon diameter values > or =10 cm (7/7 deceased patients) were indicative of poor prognosis.

Conclusions: MDCT can identify the presence and site of malignant large-bowel obstructions and may provide useful prognostic information.
