【摘要】:目的:探讨胆道梗阻并发胆道感染的相关因素,为胆道感染的诊断、治疗及预防提供参考。方法:回顾性分析2015年9月~2016年10月于遵义医学院附属医院接受PTCD/PTGD术治疗的胆道梗阻患者114例,其中男65例,女49例,年龄35~91岁,平均65.57岁,术前梗阻时间平均24.51天。所有病例均行超声、CT或MRI等影像学检查,同时行肝功能、血常规、肿瘤抗原标志物等实验室检查,并在术中抽取胆汁行细菌培养。根据临床表现、影像学检查、实验室检查及胆汁细菌培养结果诊断是否存在胆道感染。收集患者胆道梗阻相关临床资料:性别(男、女)、年龄(≥60岁、60岁)、病因(肿瘤性、结石性)、病程时间(≥10、10天)、梗阻部位(高位梗阻、低位梗阻)、梗阻程度(完全性、不全性)、胆道手术史(有、无)、肝功能Child-Pugh评分(11、≥11分)、术前碱性磷酸酶浓度(300 U/L、300-600 U/L、≥600 U/L)、胆汁细菌培养结果(阳性、阴性)等10项指标作为研究参数。应用SPSS17.0统计软件进行分析,P0.05差异有统计学意义。结果:114例胆道梗阻患者合并胆道感染67例,感染率为58.9%(67/114),共分离出微生物98株,常见的微生物依次为大肠埃希菌28.6%(28/98)、肺炎克雷伯杆菌12.2%(12/98)、粪肠球菌7.1%(7/98)、屎肠球菌5.1%(5/98)、阴沟肠杆菌5.1%(5/98)。胆道感染相关因素单因素分析:性别(c2=0.023,P=0.394)、年龄(c2=0.136,P=0.432)、术前碱性磷酸酶浓度(c2=5.593,P=0.054)三项参数差异无统计学意义(P0.05);梗阻病因(c2=18.958,P=0.000)、病程时间(c2=17.365,P=0.000)、梗阻部位(c2=4.634,P=0.026)、梗阻程度(c2=8.144,P=0.004)、胆道手术史(c2=5.530,P=0.015)、肝功能Child-Pugh评分(c2=5.955,P=0.012)、胆汁细菌培养阳性(c2=6.958,P=0.009)是胆道梗阻并发胆道感染的相关因素,差异有统计学意义(P0.05),其中结石性梗阻、起病急、低位梗阻、不全性梗阻、有胆道手术史、肝功能Child-Pugh评分≥11分、胆汁细菌培养阳性是胆道梗阻并发胆道感染的高危因素。上述高危因素采用多因素Logistic分析结果显示结石性梗阻、有胆道手术操作史、肝功能评分≥11分、胆汁细菌培养阳性是胆道梗阻并发胆道感染的独立危险因素。结论:胆道梗阻易并发胆道感染,结石性梗阻、病程时间短、低位梗阻、不全性梗阻、有胆道手术史、肝功能Child-Pugh评分≥11分、胆汁细菌培养阳性是胆道梗阻并发胆道感染的高危因素;其中结石性梗阻、胆道手术史、肝功能评分高、胆汁细菌培养阳性是胆道梗阻并发胆道感染的独立危险因素。
[Abstract]:Objective: to investigate the related factors of biliary tract infection in biliary obstruction, and to diagnose biliary tract infection. Methods: from September 2015 to October 2016, 114 patients with biliary obstruction treated with PTCD/PTGD in affiliated Hospital of Zunyi Medical College were analyzed retrospectively, including 65 males and 49 females, aged 35 to 91 years, with an average of 65.57 years old. The mean time of obstruction before operation was 24.51 days. All the patients were examined by CT or MRI, and the liver function, blood routine, tumor antigen markers and other laboratory examinations were performed simultaneously, and the bile was extracted during the operation for bacterial culture. Imaging examination, laboratory examination and bile bacterial culture were used to diagnose the presence of biliary tract infection. Clinical data related to biliary obstruction were collected: sex (male, female, age 鈮,
