动脉化疗栓塞治疗恶性梗阻性黄疸

目的：探讨胆道支架置放后动脉化疗栓塞治疗恶性梗阻性黄疸(MOJ)的并发症和疗效，研究影响黄疸复发时间和患者生存期的预后因素。方法：51例MOJ患者放置胆道支架后接受动脉化疗栓塞术(TACE)，观察手术并发症，血清胆红素下降程度，随访黄疸复发时间和患者生存期。分析性别，年龄，肿瘤类型，术前血清胆红素浓度、碱性磷酸酶、谷丙转氨酶、白蛋白、血红蛋白浓度，梗阻时间，梗阻水平10个因素对黄疸复发时间和患者生存期的影响。结果：51例共计放置支架64枚，行TACE术86次，技术成功率为100％。1例于术后1个月死亡，在治疗过程中，4例出现肝脓肿。4例失访，51例生存期为1～34个月，平均9．0个月，中位值8．0个月。22例黄疸复发，复发率43．2％，黄疸复发时间2～14个月，平均11．0个月，中位值9．0个月。单因素(P=0．010)和多因素(P=0．010)分析均显示术前血清总胆红素浓度是影响患者生存期的重要因素。单因素分析显示对黄疸复发有显著影响的因素为肿瘤类型(P=0．035)。结论：MOJ患者放置胆道支架后进行TACE术，可以延缓黄疸复发，延长患者生存期。术前血清总胆红素浓度高的患者生存期较短；肝细胞肝癌患者的黄疸复发时间较非肝细胞肿瘤患者明显延长，黄疸复发率亦低于后者。

金属内支架置入联合三维适形放射治疗肝癌合并门静脉癌栓

Objective To study the clinical efficiency of metallic stent implantation in combination with three-dimensional conformal radiation therapy in the treatment of hepatocellular carcinoma (HCC) pa-tients with portal vein tumor thrombus. Methods 22 cases of HCC patients with portal vein tumor thrombus were devided into 2 groups: 10 patients (group A) recieved stent implantation in combination with conformal radiation therapy, 12 patients (group B) recieved stent implantation and transcatheter arterial chemoembolization. The adverse reactions, and liver function before and after treatment were compared between the two groups. The stent patency rate at 4, 6 and 12 months and the survival rate at 3, 6 and 12 months were followed up. Comparison of liver function was analyzed by Wilcoxon signed rank test. Compari-son of stent patency rate curves and survival curves was analyzed by Log rank test. Results The portal vein catheterization was successful in all the patients. The stents were successfully implanted by transhepatic portal vein approach, and portal vein stenosis was re-opened. There was no abdominal hemorrhage in all the patients, but there were symptoms of abdominalgia, fever, nausea, vomiting and flatulence of varying de-grees after interventional operation, and these symptoms were relieved by symptomatic treatment in one week. All patients in group A completed the treatment. Ⅰ-Ⅱ degree gastrointestinal tract reactions occurred in 3 cases, Ⅰ-Ⅱ degree myelosuppression occurred in 2 cases, and they were all completely relieved after treatment. The stent patency rate at 4, 6 and 12 months was 90%, 70%, 30% in group A; and 50%, 25%, 16.7% in group B (P < 0.05). The survival rate at 3, 6 and 1 2 months was 100%, 80%, 30% in group A and 91.7%, 41.7%, 16.7% in group B (P < 0.05). Conclusion Stent implantation combined with three-dimensional conformal radiation therapy is a good treatment for hepatocellular carcinoma with portal vein tumor thrombus and causes less damage to liver.

目的:探讨经直肠超声造影(CEUS)和磁共振成像(MRI)诊断前列腺癌(PCa)有关问题,评价二者的诊断价值。方法:选取有完整相关临床资料的患者48例,对患者行前列腺超声造影及MRI检查,并与病理检查结果进行比较。结果:48例患者经病理检查证实为PCa 30例。经直肠CEUS诊断符合率为77.08%,敏感性为80.00%,与MRI的符合率(79.16%)、敏感性(76.67%)比较,差异无统计学意义(P>0.05),但其特异性(72.22%)低于MRI的特异性(83.33%),差异有统计学意义(P<0.05)。二者联合诊断的符合率为89.58%,敏感性为90.00%,特异性为88.89%,与单独一种诊断比较,差异均有统计学意义(P<0.05)。结论:经直肠CEUS及MRI对PCa的诊断各有优势,经直肠CEUS联合MRI可提高PCa的检出率。
