Radiologic Evaluation and Structured Reporting Form for Extrahepatic Bile Duct Cancer: 2019 Consensus Recommendations from the Korean Society of Abdominal Radiology.

ABSTRACT: Radiologic imaging is important for evaluating extrahepatic bile duct (EHD) cancers; it is used for staging tumors and evaluating the suitability of surgical resection, as surgery may be contraindicated in some cases regardless of tumor stage. However, the published general recommendations for EHD cancer and recommendations guided by the perspectives of radiologists are limited. The Korean Society of Abdominal Radiology (KSAR) study group for EHD cancer developed key questions and corresponding recommendations for the radiologic evaluation of EHD cancer and organized them into 4 sections: nomenclature and definition, imaging technique, cancer evaluation, and tumor response. A structured reporting form was also developed to allow the progressive accumulation of standardized data, which will facilitate multicenter studies and contribute more evidence for the development of recommendations.

Project description:IntroductionThe peribiliary gland is an accessory bile duct gland. Hyperplasia of these tissues may lead to elevation of the mucosa in the bile ducts and bile duct stenosis. We herein report a case of peribiliary gland hyperplasia that required preoperative differentiation from bile duct cancer, with a discussion of the literature.Case presentationThe patient had an adenomatous lesion in the ascending colon that was difficult to treat endoscopically; therefore, surgery was planned. Preoperative abdominal ultrasonography revealed a bile duct tumor, and endoscopic ultrasonography revealed a mass lesion around the confluence of the cystic duct. Computed tomography revealed localized wall thickening in the middle bile duct, and the upstream bile ducts were slightly dilated. In addition, continuous thickening of the bile duct wall from the gallbladder to the confluence of the cystic duct was observed. No distant metastases, such as liver metastases, or nearby enlarged lymph nodes were observed. Endoscopic retrograde cholangiopancreatography and magnetic resonance cholangiopancreatography revealed a papillary-like elevated lesion in the bile duct near the confluence of the cystic duct, and a biopsy and bile cytology from the same area showed no malignant findings. As a result, the possibility that the patient had gallbladder or bile duct cancer could not be ruled out; therefore, a policy of surgery together with the ascending colon tumor was decided after receiving sufficient informed consent. During surgery, the patient underwent extrahepatic bile duct resection, reconstruction of the biliary tract using the Roux-en-Y method, and right hemicolectomy. Both duodenal and hilar bile duct transects were subjected to a fast frozen section analysis during surgery, and the results were negative for cancer. A histopathological examination of the resected specimen revealed no malignant findings in the bile duct lesions, and a diagnosis of peribiliary gland hyperplasia with chronic inflammatory cell infiltration and fibrosis of the extrahepatic bile duct wall was made.ConclusionsWe encountered a case of peribiliary gland hyperplasia that was difficult to distinguish from bile duct cancer.
