目的探讨超声下经皮经肝胆管穿刺置管引流术在梗阻性黄疸的临床应用价值。方法应用彩色多普勒超声引导对51例梗阻性黄疸患者进行经皮经肝胆管穿刺置管引流术，并将治疗结果进行分析。结果51例梗阻性黄疸患者总成功率为94.1％（48/51），一针穿刺成功率达88.2％（45/51）。穿刺胆管直径范围4-11mm。平均直径为6.5mm，术后胆汁引流量平均为620ml/d ，并发症发生率为0.5％。结论彩色超声引导下的经皮经肝胆管引流术穿刺置管简便、安全、成功率高，可作为治疗梗阻性黄疸外引流的有效方法。“,”Objective To determine the clinical value of ultrasound-guided percutaneous transhepatic bile drainage (UPTBD)in treatment of obstructive jaundice. Methods UPTBD was performed in 51 patients with obstructive jaundice and tube was inserted to the bil ary duct in al patients. Results Among the 51 patients,the overal success rate was 94.1%(48/51),and the success rate of single centesis was 88.2%(45/51).The diameter of biliary duct ranged from 4mm to 11mm,the mean diameter was 6.5mm,the mean amount of daily bile drainage was 620ml ,and the rate of complication was 0.5%(3/51). Conclusions UPTBD is an effective alternative for bile duct drainage,with advantages of minimal invasion,simple performance ,little pain ,and a high success rate. Hence it is an important method for the treatment of biliary obstructive diseases.
