肝外胆管癌、壶腹部癌和胰头癌常导致梗阻性黄疽,诊治较为棘手。近年来、随着影象学诊断技术的发展,术前诊断率已显著提高,疗效亦有改善。1984年以来,作者采用B超,CT和PTC等影象技术诊断梗阻性黄疸,发现肝外胆管癌、壶腹部癌和胰头癌60例,现将经手术和病理证实的30例分析如下,并就有关诊治问题进行讨论。临床资料 Extrahepatic bile duct carcinoma, ampullary carcinoma and pancreatic head cancer often lead to obstructive jaundice, and diagnosis and treatment are more difficult. In recent years, with the development of diagnostic imaging techniques, the preoperative diagnosis rate has been significantly improved, and the curative effect has also improved. Since 1984, the authors have used B ultrasound, CT, and PTC imaging techniques to diagnose obstructive jaundice and found 60 cases of extrahepatic bile duct, ampulla, and pancreatic head cancer. The 30 cases confirmed by surgery and pathology are analyzed as follows. And discuss the relevant problems of diagnosis and treatment. clinical information
