摘要
目的:探讨介入治疗恶性梗阻性黄疸的效果及价值,并分析影响患者生存时间的相关因素。方法:回顾性分析我院2006年-2010年恶性梗阻性黄疸病例146例,其中男84例、女62例,平均年龄(63±13)岁,所有患者术前均行彩色B超或CT或MRI检查,并行实验室检查。先行经皮经肝胆道穿刺,随后针对不同部位的梗阻分别置入引流管行胆道引流(PTBD)或置入胆道内支架(PTBS);术后给予抗感染、保肝、抗肿瘤及对症治疗,复查影像学或生化变化;术后1周,37例行肝动脉化疗栓塞(TACE);并对其中139例通过门诊及电话随访;另外还对性别、年龄、病因、梗阻部位及生化指标等因素对生存时间的影响进行了分析。结果:146例病例均成功穿刺并置入引流管(105例)及植入支架(41例),手术成功率100%,术后129例患者黄疸等症状好转,总有效率88.4%;PTBD及支架引流术前总胆红素(TB)、血清丙氨酸转氨酶(ALT)、直接胆红素(DB)、血清碱性磷酸酶(ALP)、γ-谷氨酰转肽酶(γ-GT)及血清白蛋白水平较术后降低,进行独立样本t检验,三种不同引流方法在减轻黄疸,改善肝功能,延长生存期方面差异有统计学意义(P<0.05);PTBS减轻黄疸的幅度优于PTBD,但黄疸缓解的比例组间无差异;37例患者术后1周接受了TACE治疗,对治疗前后TB.DB.ALT.ALP行t检验,有统计学差异(P<0.05);三种引流方式对生存率影响有显著性差异(P=0.000);单纯外引流组、内外引流组及胆道支架组的中位生存期分别为3.3月、5.0月及7.3月,PTBS组在生存期方面亦优于PTBD组,术前TB及白蛋白水平对预后有意义。结论:PTBD/PTBS是治疗恶性梗阻性黄疸的一种有效的姑息性治疗方法,能有效减轻黄疸,缓解临床症状,尽可能在早期行PTBD/PTBS,以最大程度改善患者生活质量。术后行TACE治疗可明显加快胆红素水平下降的幅度,术前TB及白蛋白水平是影响术后生存时间的主要因素,对患者的预后可做初步预测。
Objecfive:Malignant obstructive jaundice is a common disease clinically, and when diagnose, most of the patients have lost the opportunity of operative eradication, operation. PTBD/PTBS have become one of the main therapeutic method of malignant obstructive jaundice which has lost operative opportunity. They have certain curative effect, small trauma and liess complication. This study aim at the clinical outcome and its relative influencing factors of interventional therapy in dealing malignant obstructive jaundice(MOJ). Methods:Between October 2006 and February 2010, one hundred and forty six MOJ patients,84 males and 62 females, aged(63±13), underwent interventional therapy:105 patients received percutaneous transhepatic biliary drainage(PTBD) including external drainage or external-internal drainage, and 41 underwent percutaneous transhepatic biliary stent(PTBS) implantation. No major complications associated with the execution of PTBD occurred. The various symptoms caused by jaundice, such as anorexia, itching, nausea, abdominal pain and fever, were relieved in one hundred and twenty nine patients within one week after PTBD.3-7days after the procedure, total bilirubin(TB), direct bilirubin(DB), alanine transaminase(ALT), alkaline phosphatase(ALP), y-glutamyl transpeptidase(y-GT) and albumin were examined. One week after,37 of the patients underwent transcatheter arterial chemoembolization(TACE). Results:One week after drainage, the levels of ALT, TB, DB, ALP,γ-GT and albumin of the patients underwent PTBD and PTBS all decreased in comparison with the baseline level(P<0.05). The levels of the PTBS group were significantly lower than those of the PTBD group, but the difference was not statistically significant among these 3 groups. The levels of ALT, TB, and DB of 37 patients underwent TACE all decreased in comparison with those before the treatment(P<0.05). The mean survival time of the external drainage group and external-internal drainage group was 3.3 and 5.0 months respectively, the PTBS group was 7.3 months. Conclusions:PTBD/PTBS is a technically feasible, and safe and clinically efficacious treatment for malignant biliary obstruction. It can relieve the clinical symptom and alleviate jaundice effectually; Therefore, the patients should receive PTBD in the early time in order to improve the life quality maximumly. Furthermore, TACE therapy following PTBD and PTBS will be significantly beneficial to decrease TB of MOJ patients.
