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.

Background And Aims: The therapeutic management of fistulas presents significant challenges, often involving both conservative and surgical approaches. Despite these interventions, recurrence and postoperative mortality rates remain high. Endoscopic stent insertion into the fistula, along with the creation of a stent stoma, may offer a promising alternative for patients who fail surgical or conservative therapies.

We present a case of a woman in her 70s who arrived in the emergency department with signs of small-bowel obstruction. CT scanning revealed acute cholecystitis with a cholecystoduodenal fistula, pneumobilia and small-bowel obstruction possibly secondary to gallstone ileus although no radio-opaque gallstones were seen. The patient underwent an emergency operation and intra-operative findings revealed mechanical small-bowel obstruction of the proximal jejunum where a 4×2 x 3 cm gallstone was impacted.
