Abstract: Objective To evaluate the value of intra-cavitary contrast-enhanced ultrasound (IC-CEUS) via abdomen in fistulas difficult to diagnose before operation.Methods Clinical data of 12 patients with preoperative clinical suspicion of Crohn's Disease (CD) complications of fistula were enrolled in the study.Colonoscopy,cystoscope,or CT/MR has not confirmed the diagnosis of intra abdominal fistulas.IC-CEUS were performed by locally-injection of contrast agent in abdominal abscess,observing fistula and the relationship with the adjacent organs in CEUS mode.Diagnostic criteria were surgical findings.Results Fistulas in 10 patients were detected by IC-CEUS,including 7 cases of Ileo-mesenteric fistuls,2 cases of il eo-vesical fistulas,and 1 case of colo-vesical fistula.The accuracy rate of IC-CEUS in diagnosis of fistulas difficult to diagnose before operation in Crohn's disease was 83.3％ (10/12).No severe adverse events occurred during and after IC-CEUS procedure.Conclusions Our preliminary study shows that IC-CEUS is feasible in detecting abdominal fistula with high accuracy.It might be used as the alternative imaging tech nique for detecting fistulas when CT and MR are insufficient.
