欲对胆道损害所致阻塞性黄疸病人作外科处理,首先应明确病变是良性或恶性。正确的术前诊断也有利于姑息性化疗时选择药物.在超声波引导下的抽吸术和/或针刺活检通常用作肝胰疾病的术前诊断方法.但此法并不完全适用于胆道及有关疾病。因为肿瘤太小以至穿刺不到或癌细胞已侵润胆管壁使适当取材已无可能。用此法诊断胆道系统癌症的成功率仅为53%.本文作者介绍用一种特制胆道导管经皮肝穿作胆道脱落细胞学检查和胆道活检的技术及实用价值。本组病例为男15例,女4例。年龄38～79岁,均
For surgical treatment of patients with obstructive jaundice caused by biliary lesions, it should be clear that the lesions are benign or malignant. Correct preoperative diagnosis also favors the choice of drugs for palliative chemotherapy. Ultrasound-guided aspiration and/or acupuncture biopsy are commonly used as preoperative diagnostic methods for hepato-pancreatic diseases. However, this method is not entirely applicable to biliary tracts. And related diseases. Because the tumor is too small to puncture or cancer cells have invaded the bile duct wall, it is no longer possible to obtain suitable materials. The success rate of using this method for diagnosing biliary system cancer is only 53%. The authors of this paper introduced the technique and practical value of percutaneous transhepatic biliary exfoliative cytology and biliary biopsy using a special biliary duct. This group of cases were 15 males and 4 females. Age 38 to 79 years old, both
