对手术病理证实的肝外胆管癌29例,进行回顾性分析。其中上段癌16例(55.2％);下段癌11例(37.9％);中上段癌2例(6.9％)。除2例为乳头状腺瘤癌变,1例为横纹肌肉瘤外,余均为腺癌。影像学诊断在发现肿瘤,明确病因及梗阻水平上依次为PTC3例(100％);ERCP26例(92.3％);CT18例(88.8％);B超29例(82.7％)。但B超简易、无创、经济方便,应首选;CT无痛苦,准确率高,可作为确定诊断的依据;PTC及ERCP虽为介入性影像学检查,但对肝外胆管癌早期诊断及肿瘤的定位、定性准确率高,且可清晰显示胆道系统的全貌,对治疗及手术方案选择有重要指导意义。
Twenty-nine cases of extrahepatic bile duct carcinoma confirmed by surgical pathology were retrospectively analyzed. Among them, 16 cases (55.2%) were upper carcinomas, 11 cases (37.9%) were lower carcinomas, and 2 cases (6.9%) were middle and upper carcinomas. In addition to 2 cases of papillary adenoma, 1 case of rhabdomyosarcoma, the rest were adenocarcinoma. Diagnosis of imaging revealed tumors in 3 cases (100%) of PTCs, 26 cases of ERCP (92.3%), 18 cases of CT (88.8%), and 29 cases of B-ultrasound (82.7%). However, B ultrasound is simple, non-invasive, and economical, it should be the first choice; CT has no pain, high accuracy, can be used as a basis for determining the diagnosis; PTC and ERCP although interventional imaging examination, but the early diagnosis of extrahepatic bile duct cancer and tumor It has high accuracy in positioning and qualitative accuracy, and can clearly show the complete appearance of the biliary system. It has important guiding significance for the choice of treatment and surgical plan.
