目的

探究恶性胆道梗阻患者行经皮经肝胆道支架植入术后并发胆道感染的系列影响因素,以在今后临床工作中降低胆道感染并发症的发生。

方法

对2015年1月-2019年8月在我院行经皮经肝胆道支架植入术的恶性胆道梗阻患者共69例行回顾性分析。根据术后1个月之内是否并发胆道感染分成两组(胆道感染组和非胆道感染组)。两组中患者因素和手术因素被评估分析(其中连续变量采用t检验,分类变量采用χ2检验,二元Logistic多因素分析得出独立危险因素)。

结果

69例(胆道感染组17例,非胆道感染组52例)患者入组,单因素分析显示:支架类型(P = 0.038)、125I粒子数量(P = 0.028)、手术操作时间(P = 0.007)、术中是否并发胆道出血(P = 0.003)、术后支架通畅时间(P = 0.025)与经皮胆道支架植入术后胆道感染相关。单纯粒子支架组内分析显示:125I粒子数量(P = 0.048)、手术操作时间(P = 0.001)与术后胆道感染呈正相关。最后行二元Logistic多因素分析得出手术操作时间(OR = 1.040,P = 0.043)是术后并发胆道感染的独立危险因素。

结论

经皮胆道125I粒子支架较裸支架术后胆道感染发生率增高,并且随着125I粒子数量增加感染率随之提高。随着手术操作时间增加,胆道感染的发生率增加。

Objective

To investigate the factors associated with biliary tract infection after percutaneous biliary stent implantation in order to reduce the incidence of biliary tract infection.

Methods

A total of 69 patients with malignant biliary obstruction who underwent percutaneous biliary stent implantation in our hospital from January 2015-August 2019 were retrospectively analyzed. The patients were divided into biliary tract infection group and non-chiliary tract infection group. patient factors and surgical factors were assessed and analyzed in both groups. the continuous variables were tested by t test, and the classified variables were tested by χ2 test, and the meaningful indexes in single factor analysis were analyzed by binary Logistic multivariate regression analysis to screen out independent risk factors.

Results

Among 69 patients, 17 were biliary tract infection and 52 were non-biliary tract infection. Univariate analysis showed that: stent type (P = 0.038), 125I particle number (P = 0.028), operative time (P = 0.007), intraoperative concurrent biliary bleeding (P = 0.003), postoperative stent patency (P = 0.025) were associated with postoperative biliary infection after percutaneous biliary stent implantation. 125I intra-group analysis showed that the number of 125I particles (P = 0.048) and operation time (P = 0.001) were positively correlated with postoperative biliary tract infection. Binary Logistic multivariate regression analysis revealed that operation time (OR = 1.040, P = 0.043) was an independent risk factor for biliary tract infection after percutaneous biliary stent implantation.

Conclusions

Percutaneous biliary tract 125I seed stent placement has a higher incidence of biliary tract infection than bare stent placement, and the infection rate increases as the number of 125I seeds increases. Longer operation time could increase, the higher the incidence of biliary tract infection.
