摘要

以real-time echo對13名正常者或病患（男5，女8，年齡自32至60歲）做檢查，並與IVC之結果相比較。10名正常者之real-time echo總肝管內徑為2至6mm，IVC者為3至10mm；3名膽道結石症病患之real-time echo總肝管內徑為4至11mm，IVC者為4至12mm。IVC總肝管內徑為real-time echo者之1至1.7倍。13名受檢者中，有10名之real-time echo可顯現主膽道由窄而寬而後窄的整體變化，其總膽管內徑最寬處為4至13mm（正常者7名，為4至9mm；病患3名，為9至13mm），其相對IVC總膽管最寬內徑為5至14mm（正常者為5至12mm，病患為12至14mm）；IVC結果為real-time echo者之1至1.5倍。real-time echo測定之總肝管與總膽管內徑與IVC者相符合或較小，其原因在本文中亦詳加探討。real-time echo與IVC皆能將主膽道之擴張表現出來。

並列摘要

Thirteen persons were studied by real-time abdominal echography (echo) and intravenous cholangiography (IVC) to detect the internal dimension of common hepatic duct (CHDd) and common bile duct (CBDd). Among them 10 were normal and 3 had cholelithiasis with or without choledocholithiasis. The echo-CHDd was measured as the dimension of CFID at the posterior hepatic margin just anterior to the portal venous system; it was 3 to 6mm in normal subjects and 4 to 11mm in diseased ones. The IVC-CHDd was measured at the most narrow portion of the CHD; it varied from 3 to 10mm in the normals and 4 to 12mm in the diseased. The CBDd represented the greatest internal dimension of CBD. Echo-CBDd was 4 to 9mm in 7 normal subjects and 9 to 13mm in the diseased; IVC-CBDd was 5 to 12mm and 12 to mm correspondingly. Although IVC-CHDd and -CBDd were found equal to or greater than echo-CHDd and CBDd respectively, both methods were able to disclose dilation of the main bile duct.
