摘要: 目的 探讨使用不同造影剂剂量行逆行胰胆管造影术(ERCP)对恶性胆道梗阻患者肝功能指标的影响及疾病预后分析。方法 2013年8月~2016年8月我院收治的行ERCP术的134例胆道梗阻患者,其中胆管癌50例,胰头癌34例和胆囊癌50例。随机将患者分为两组,小剂量组应用50%碘海醇小于15 ml行ERCP患者67例,大剂量组应用造影剂量大于15 ml者67例。分别检测患者术前和术后肝功能指标变化,包括碱性磷酸酶(ALP)、谷草转氨酶(AST)、谷丙转氨酶(ALT)、总胆红素(TBIL)和谷氨酰转肽酶(GGT)。比较两组患者ERCP术后不良反应发生情况,以及两组患者总生存期的变化。结果 小剂量组患者血清ALT水平术后7 d(131.3±16.9 U/L)、术后14 d(111.1±17.2 U/L)、术后21 d(104.3±13.5 U/L)和术后28 d(88.1±12.9 U/L)比术前(151.3±26.4 U/L)均降低(P<0.05),而大剂量组患者血清ALT水平术后7 d(150.3±16.2U/L)、术后14 d(148.3±17.2U/L)、术后21 d(146.3±13.4U/L)和术后28 d(146.1±12.2U/L)比术前(153.3±26.4U/L)无明显变化(P>0.05);小剂量组患者血清ALP水平术后7 d(143.3±16.5 U/L)、术后14 d(121.1±17.2 U/L)、术后21 d(104.3±13.7 U/L)和术后28 d(90.3 ±12.2 U/L)比术前(163.1±31.4 U/L)呈逐渐降低(P<0.05),而大剂量组患者术后7 d(161.1±16.5 U/L)、术后14 d(160.1±17.2 U/L)、术后21 d(158.3±13.7 U/L)和术后28 d(157.1±12.2 U/L)比术前(162.3±31.4 U/L)比,无显著变化(P>0.05);小剂量组患者术后胆道感染发生率(4.5%)较大剂量组(14.9%)明显减低(P<0.05);大剂量组术后总生存期(19.96±9.39)个月,显著短于小剂量组总生存期的(31.2±11.4)个月;多重变量分析表明,造影剂剂量是影响患者总生存期(HR=2.383,95% CI 1.262~4.503,P=0.003)的独立危险因素。结论 应用小剂量(小于15 ml)50%碘海醇行ERCP手术对胆道梗阻患者肝功能指标几乎无影响,而应用大剂量(大于15 ml)50%碘海醇行ERCP手术可能对患者造成肝损伤,且术后胆道感染发生率高,疾病预后差,应注意斟酌。

Abstract: Objective To investigate the impact of different doses of contrast agent iohexol in undergoing endoscopic retrograde cholangiopancreatography(ERCP) on liver function index and prognosis in patients with malignant biliary obstruction. Methods 134 patients with malignant biliary obstruction(including 50 with cholangiocarcinoma,34 with pancreatic carcinoma and 50 with gallbladder caicinoma) underwent ERCP in our hospital between August 2013 and August 2016 were recruited in this study,and the patients were divided into low-dose of contrast agent group (n=67) and large-dose of contrast agent group(n=67). Serum levels of ALT,AST,ALP,GGT and TBIL were determined preoperatively and postoperatively in these patients. Complications and overall survival were observed and compared between them. Results At 7 d,14 d,21 d and 28 d after ERCP,serum alanine aminotransferase levels in low-dose of iohexol were(131.3±16.9 U/L),(111.1±17.2 U/L),(104.3±13.5 U/L) and (88.1±12.9 U/L),much lower than (151.3±26.4 U/L) before ERCP (P<0.05),while in large-dose iohexol were (150.3±16.2 U/L),(148.3±17.2 U/L),(146.3±13.4 U/L)and(146.1±12.2 U/L),no significant change as compared to (153.3±26.4 U/L) before ERCP (P>0.05);serum ALP levels in low-dose group were(143.3 ±16.5 U/L),(121.1±17.2 U/L),(104.3±13.7 U/L) and(90.3±12.2 U/L),much lower than(163.1±31.4 U/L) before ERCP(P<0.05),while in large-dose group were (161.1±16.5 U/L),(160.1±17.2 U/L),(158.3±13.7 u/L) and (157.1±12.2 U/L),no significant change as compared to(162.3±31.4 U/L)before ERCP (P>0.05);the infection of biliary tract in low-dose of contrast agent group were 4.5%,significantly lower than in high-dose of contrast agent group(14.9%,P<0.05);the overall survival in large-dose group were(19.96±9.39) months,significantly lower than(31.2±11.4) months in low-dose of contrast agent group(P<0.05);multivariate analysis showed than the dose of contrast agent was an independent factor for poor prognosis (HR=2.383,95% CI 1.262~4.503,P=0.003) in patients with malignant biliary obstruction. Conclusion Low-dose of contrast agent iohexol underwent ERCP does not affect liver function tests,while large-dose of contrast agent might lead to liver dysfunction and poor prognosis.
