肝外胆管癌是一种较为少见的原发于肝外胆管上皮的恶性肿瘤,临床上无特殊症状,不易早期识别,为此对我院1991～1995年手术病理证实的30例肝外胆管癌进行回顾性分析,以探讨在影像学诊断方面的选择与应用。一、临床资料 30例病人均为住院患者,男16例,女14例,年龄5～79岁,其中50岁以上者27例。全部病人均表现有黄疸,其中伴搔痒24例,大便色淡22例,乏力20例,食欲不振18例,上腹饱胀15例,直接胆红素/总胆红素比值>60%20例,ALT 升高8例。全部病例均经手术病理证实,同时术前作 B 超、ERCP 及腹部 CT 等影像学检查。二、结果手术证实上段胆管癌16例、下段12例、中上段2例,病理证实腺癌27例、乳头状腺瘤癌变2例、横纹肌肉瘤1
Extrahepatic cholangiocarcinoma is a relatively rare malignant primary tumor in the extrahepatic bile duct epithelium. There are no special clinical symptoms and it is difficult to identify early. Therefore, 30 cases of extrahepatic bile duct carcinoma confirmed by surgery and pathology in our hospital from 1991 to 1995 were diagnosed. A retrospective analysis was performed to explore the selection and application of imaging diagnostics. First, clinical data 30 patients were hospitalized patients, 16 males and 14 females, aged 5 to 79 years old, of which more than 50 years of age in 27 cases. All patients showed jaundice, including 24 cases with pruritus, 22 cases with pale stools, 20 cases with fatigue, 18 cases with loss of appetite, and 15 cases with full abdominal bloating. The direct bilirubin/total bilirubin ratio was >60% in 20 cases. ALT increased in 8 cases. All cases were confirmed by surgery and pathology. Imaging examinations such as B-ultrasonography, ERCP, and abdominal CT were performed before surgery. 2. Results The operation confirmed 16 cases of upper bile duct carcinoma, 12 cases of lower segment, and 2 cases of middle and upper segment. Pathologically confirmed 27 cases of adenocarcinoma, 2 cases of papillary adenoma, 2 cases of rhabdomyosarcoma 1
