摘      要：AIM:Pelvic magnetic resonance imaging(MRI)and endoanal ultrasound which are established imaging methods for perianal inflammatory lesions in patients with Crohn s disease require expensive specialized equipments and *** investigated the feasibility and sensitivity of transcutaneous perianal ultrasound(PAUS)using regular ultrasound probes in the imaging of perianal inflammatory *** sonographic findings were correlated to pelvic MR]-scans. METHODS:We performed PAUS in 25 patients with Crohn s disease and clinical signs of perianal inflammatory disease. Wibhin a median of 10 d(range 0-75)these patients underwent MRI of the *** convex and linear high resolution probes were used for *** sonographic findings were correlated to the MRI findings by blinded investigators. RESULTS:The sonographic investigations were well tolerated by all *** typically presented as hypoechoic ***-nine fistulae were detected in 22 *** were detected in 7 patients and presented as hypo-or anechoic ***-six of 29 fistulae and 6 of 7 abscesses could be confirmed by *** statistics showed an excellent agreement (kappa0.83)between the two imaging methods. CONCLUSION:PAUS is a simple,painless,feasible,real- time method that can be performed without specific patient preparation which is comparable in its sensitivity to pelvic MRI in the detection of perianal fistulae and/or abscesses. PAUS can especially be recommended as a screening tool in acute perianal disorders such as perianal abscess and for follow-up studies of perianal inflammatory disease.
