BACKGROUND
We investigated the utility of a new imaging modality, three-dimensional intraductal ultrasonography (US), for staging bile duct cancer.
METHODS
In eight patients with extrahepatic bile duct carcinoma, two- and three-dimensional intraductal US was used to assess tumor invasion of the right hepatic artery, portal vein, and pancreatic parenchyma before resection. The findings were correlated with histologic information from the resected specimen.
RESULTS
Three-dimensional intraductal US enabled accurate assessment of tumor invasion of the right hepatic artery in 88% of cases, the portal vein in 100%, and pancreatic parenchyma in 100%. Two-dimensional intraductal US enabled accurate assessment of invasion of these structures in 88%, 88%, and 88% of cases.
CONCLUSIONS
Three-dimensional intraductal US is useful in assessing tumor stage in bile duct carcinoma.
背景
我们研究了一种新的成像方式——三维导管内超声检查（US）在胆管癌分期中的应用价值。
方法
对8例肝外胆管癌患者，在切除术前使用二维和三维导管内超声评估肿瘤对右肝动脉、门静脉和胰腺实质的侵犯情况。研究结果与切除标本的组织学信息进行对比。
结果
三维导管内超声能够在88%的病例中准确评估肿瘤对右肝动脉的侵犯情况，在100%的病例中准确评估对门静脉的侵犯情况，在100%的病例中准确评估对胰腺实质的侵犯情况。二维导管内超声能够在88%、88%和88%的病例中准确评估这些结构的侵犯情况。
结论
三维导管内超声有助于评估胆管癌的肿瘤分期。
