目的:探讨彩超引导下PTBD术的临床应用价值。方法:在带有穿刺附加器的彩超引导下,用18g针穿入预定扩张的胆管内,通过导丝置入引流导管。结果:38例病人共穿刺50次,一次穿刺成功46例,一次置管成功40例,失败1例。38例病人中,黄疸均有不同程度减退,11例降至正常,肝功能和临床症状有不同程度改善,1rn例带管存活一年余。5例择期手术,16例行肝动脉介入治疗。结论:超声引导PTBD术直观、简便、准确、有效,彩超引导PTBD术能进一步提高手术成功率。“,”OBHECTIVE: To explore the value of the clinic application of percutaneous transhepatic biliary drainagern(PTBD) under the color Doppler ultrasound guidance for the patients with obstructive jaundice. METHODS: 50 times PTBDrnwere done in the 38 cases under the color Doppler ultrasound with puncture-guide equipment by 18g needle, and the 7 - 8Frnduct was inserted in bile duct punctured by “J” type guide wire. RESULTS: 46 times of puncture and 40 times of insertingrnconduit were successful on the first time. Only one case was failed. The jaundice of 38 eases was relieved in different degree,rncropping to normal 11 cases. Clinical signs and liver functions of the patients were improved. Survive with conduit over onernyear was 1 case. CONCLUSION: PTBD in US-guided is simple, direct, current, and effective. Application of color Dopplerrnultrasound can further improve the rate of PTBD success.
