title: Postoperative bile duct strictures: ultrasound and endoscopic retrograde cholangiopancreatography/percutaneous transhepatic cholangiography evaluation.
abstract: This retrospective study was undertaken to assess the role of ultrasound (US) and to compare it with endoscopic retrograde cholangiopancreatography (ERCP) and percutaneous transhepatic cholangiography (PTC) in the evaluation of post-operative common bile duct (CBD) strictures. Seventy-four patients with postoperative CBD strictures were evaluated by ERCP and/or PTC. Of these, US scans were available in 52 patients. Ultrasound findings of CBD strictures were: proximal dilatation of CBD with smooth tapering stenosis (41%); abrupt cut off of CBD (18%); and echogenic nodule, without acoustic shadowing, in 16%. Of the remainder, mild proximal dilatation of the CBD was seen in 6%, and 19% of the patients had normal US scans.
