[Computer tomography appearances of the enterocutaneous fistula classification].

OBJECTIVE

To discuss the computer tomography(CT) appearances of the enterocutaneous fistula classification.

METHODS

CT scan was performed on 754 patients with enterocutaneous fistula, which were divided into tube fistula and labiate fistula according to clinic classification, and the appearances of CT scan were analyzed respectively.

RESULTS

Five hundreds and eighteen patients (68.6%) were diagnosed as tube fistula, and CT appearance of which was a duct formed between internal hole and external hole. Two hundreds and thirty-six patients (31.4%) were diagnosed as labiate fistula,and CT appearance of which was a large external hole like labium.The basic appearance of intestine and celiac cavity in enterocutaneous fistula was inflammatory focus. The incidence of abscesses in tube fistula was higher than that in labiate fistula (P<0.01). The intestinal inflammation was more common in labiate fistula than that in tube fistula (P<0.01).

CONCLUSION

There are characteristic CT appearances in enterocutaneous fistula and CT scan is useful for classification of enterocutaneous fistula.
