Methods and Materials
We retrospectively reviewed CT images and medical records of 45 cases of nontraumatic colonic perforations with histopathologically proven by surgery from May 2004 to April 2011.
Among 45 cases,
15 cases were excluded:
11 cases with perforated colon cancer;
2 case with bowel ischemia by TAE;
and 2 case with sigmoid colonic diverticulitis.
The rest 30 cases of 29 patients were spontaneous colonic perforations.
(one patient had two independent events.)
(M : F = 18 : 11,
Mean age: 68years,
range 39-92years)
We focused our attention on
- Clinical manifestations,
- Pathologic examination
- Perforation site
- CT findings
1.
Specific findings of colonic perforation
- colonic focal wall defects
- fecal spillage
- extraluminal free air
2. Secondary peritonitis signs
- edematous colonic wall thickening
- pericolonic fat infiltration
- fluid collection
- peritoneal thickening with enhancement
