The paper is concerned with the results of multiprojectional ultrasound investigation of the biliferous system in 68 patients at varying time after cholecystectomy. In most cases (77.9%) signs of dilated biliary ducts were undetectable. Dilatation of the hepaticodoch was most frequently determined by choledolithiasis, stricture or stenosing papillitis, rarely--by pancreatic head cancer. Investigation of the biliary ducts in patients after cholecystectomy should be started with ultrasound tomography; endoscopic retrograde cholangiopancreatography or iv cholangiography and dynamic cholescintigraphy were indicated after the detection of the signs of dilated ducts (the anteroposterior diameter of the common hepatic duct was over 6 mm).
本文关注的是对68例胆囊切除术后不同时间的患者进行多平面超声检查胆管系统的结果。在大多数情况下（77.9%），未检测到胆管扩张的迹象。肝外胆管扩张最常见的原因是胆总管结石、狭窄或乳头狭窄性炎，很少由胰头癌引起。对胆囊切除术后患者的胆管检查应首先进行超声断层扫描；在检测到胆管扩张迹象（肝总管前后径超过6mm）后，应进行内镜逆行胰胆管造影或静脉胆管造影以及动态胆系闪烁造影。
