Radiological findings in 80 cases of gallbladder carcinoma are analysed retrospectively. Seventy-nine of the patients had been examined by US (ultrasonography), 37 by CT (computed tomography), 26 by PTC (percutaneous transhepatic cholangiography), 17 by ERCP (endoscopic retrograde cholangio-pancreaticography), nine by angiography and 27 by US-guided FNB (fine needle biopsy). US showed the primary tumour in 68% and CT in 57%. In 67 cases the tumour had spread outside the gallbladder area, causing bile duct obstruction in 41. US showed the bile duct obstruction in 39 of these cases and CT in 20 out of 22 cases. US showed 73% of the cases that had spread to the liver; the sensitivity being 68% for direct invasion and 88% for peripheral liver metastases. The corresponding percentages for CT were 68, 67 and 75%, respectively. In lymph node enlargement, US showed the nodes in 70% of cases and CT in 52%. PTC showed either stenosis or total obstruction in 25 cases and failed in one case. ERCP showed a tumour in 76% and failed in 24%. Angiography failed to show the primary tumour in two instances out of nine. The results indicate that current imaging methods are insufficient for the accurate staging of gallbladder carcinoma.
回顾性分析80例胆囊癌的放射学检查结果。79例患者接受了超声检查（US），37例接受了计算机断层扫描（CT），26例接受了经皮肝穿刺胆管造影（PTC），17例接受了内镜逆行胰胆管造影（ERCP），9例接受了血管造影，27例接受了超声引导下细针穿刺活检（US-guided FNB）。超声显示原发性肿瘤的比例为68%，CT为57%。67例患者肿瘤已扩散至胆囊区域以外，其中41例导致胆管梗阻。超声显示其中39例胆管梗阻，CT显示22例中的20例。超声显示73%的病例已扩散至肝脏；直接侵犯的敏感性为68%，肝外周转移的敏感性为88%。CT的相应比例分别为68%、67%和75%。在淋巴结肿大方面，超声显示70%的病例有淋巴结，CT显示52%。PTC显示25例有狭窄或完全梗阻，1例失败。ERCP显示76%有肿瘤，24%失败。血管造影9例中有2例未显示原发性肿瘤。结果表明，目前的成像方法不足以对胆囊癌进行准确分期。
