This prospective study aimed to identify different groups of patients with the rare pathology of biliary obstruction caused by hepatocellular carcinoma (HCC). Patients were evaluated with blood tests, chest radiography, ultrasound of the liver and endoscopic retrograde cholangiopancreatography/percutaneous transhepatic cholangiography. Patients who were potentially operable were further assessed with selective hepatic angiography and computed tomography (CT). Of the 38 patients with obstructive jaundice secondary to HCC, the levels of obstruction were extrahepatic in 19 patients and intrahepatic in 19 patients. The clinical presentations and blood biochemistry were similar in these two groups of patients. "Curative' resection was significantly more common in extrahepatic obstruction (8/19) than in intrahepatic obstruction (0/19) (chi 2 with Yates correction P = 0.001). All non-resectable tumours, except in four patients with terminally ill disease, were palliated with stents. Survival in patients who had "curative' liver resection was significantly better than in those who had no resection (median survival 25.3 vs. 2.1 months, log-rank test P = 0.004). Patients with extrahepatic biliary obstruction secondary to HCC had a better chance of being treated by liver resection, which resulted in a significantly improved survival rate compared to patients with intrahepatic obstruction.
这项前瞻性研究旨在识别因肝细胞癌(HCC)导致胆道梗阻这一罕见病理情况的不同患者群体。对患者进行了血液检查、胸部X光检查、肝脏超声检查以及内镜逆行胰胆管造影术/经皮经肝胆管造影术评估。对可能可手术的患者进一步进行选择性肝血管造影和计算机断层扫描(CT)评估。在38例继发于HCC的梗阻性黄疸患者中,19例患者的梗阻部位在肝外,19例患者的梗阻部位在肝内。这两组患者的临床表现和血液生化指标相似。“根治性”切除在肝外梗阻患者中(8/19)比在肝内梗阻患者中(0/19)更为常见(经Yates校正的卡方检验P = 0.001)。除4例终末期疾病患者外,所有不可切除的肿瘤均通过支架进行姑息治疗。接受“根治性”肝切除的患者的生存率明显高于未接受切除的患者(中位生存期25.3个月对2.1个月,对数秩检验P = 0.004)。继发于HCC的肝外胆道梗阻患者接受肝切除治疗的机会更大,与肝内梗阻患者相比,其生存率显著提高。
