摘　　要：为了解胆管癌肿瘤大小、回声与壁浸润程度的关系，本文对６４例胆管肿瘤进行了回顾性分析。超声测量肿瘤厚径、长径与壁浸润的手术病理结果相比较：以厚径１．５ｃｍ为界，≤１．５ｃｍ肿瘤３１例，与管壁浸润的三个程度Ｓ１（未侵及浆膜）、Ｓ２（侵及浆膜）、Ｓ３（侵及浆膜外）的关系分别为２５．８％（８例）、４８．４％（１９例）、２５．８％（８例）；肿瘤厚径＞１．５ｃｍ２４例，分别为１２．１％（４）、３６．４％（１２）、５１．５％（１７）。肿瘤长径≤３ｃｍＳ１、Ｓ２、Ｓ３的比例分别为２１．６％（８／３７）、４６％（１７／３７）、３２．４％（１２／３７）；＞３ｃｍ的肿瘤分别为１４．８％（４／２７）、３７％（１０／２７）、４８．２％（１３／２７）。结果显示，胆管肿瘤壁浸润的程度与肿瘤的大小无关。对肿瘤回声观察，可见弱回声肿瘤壁浸润程度的超声诊断率较高（８６％）；强回声肿瘤最低（４４％）；Sixty-four patients with extrahepatic cholangiocarcinoma were detected by ultrasonography and confirmed by operation.The tumor growth presented three manifestations:(1)localized within the duct wall(S 1),(2)serosa involved(S 2),(3)remotely involved beyond the serosa(S 3).Thirty one tumors thickness≤1 5cm,among them 8 were S 1,19 S 2 and 8 S 3.Twenty four tumors thickness>1 5cm,4 were S 1,12 S 2 and 17 S 3.Thirty seven tumors length≤3cm,8 were S 1,17 S 2 and 12 S 3.Twenty seven tumors length>3cm,4 were S 1,10 S 2 and 13 S 3.These figures proclaimed that no relationship between tumor size and extent of the tumor involvement,but higher occurrence(88%)of hypoechogenicity than hyperechogenicity(44%)of the tumor is of great significance in diagnosis of this kind of tumors.
