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 i.v. 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68例胆囊切除术后不同时间的患者胆系多平面超声检查结果。在大多数病例（77.9%）中，未检测到胆管扩张迹象。肝外胆管扩张最常见的原因是胆总管结石、狭窄或乳头狭窄炎，很少由胰头癌引起。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。
