目的 分析复杂肝内胆管结石患者行腹腔镜肝叶切除治疗术后肝断面感染的危险因素及其处理策略。 方法 回顾性分析 2014 年 1 月至 2017 年 4 月期间川北医学院附属医院对复杂肝内胆管结石行腹腔镜肝叶切除治疗的 45 例患者的临床资料,统计肝断面感染、感染病原菌分布情况、患者一般情况、手术情况、抗生素使用时间、引流管放置时间及引流量情况,并分析引起肝断面感染的危险因素。 结果 45 例行腹腔镜肝叶切除治疗复杂肝内胆管结石患者术后发生肝断面感染 13 例,感染率为 28.89%;13 例感染患者分离出 24 株病原菌,其中革兰阳性菌 9 株,革兰阴性菌 15 株;术后肝断面发生胆汁漏 16 例,断面积液、积脓 5 例;平均引流量 200 mL;术中放置双套管 10 例;术后 B 超或 CT 介入下重置引流管 23 例,引流管放置时间平均为 8 d,引起全身感染 2 例。单因素分析结果显示,既往多次胆道手术史、合并肝硬化、术中放置双套管、手术时间及术后胆汁漏与复杂肝内胆管结石行腹腔镜肝叶切除术后肝断面感染有关(P<0.050);多因素分析结果显示,既往多次胆道手术史及术后胆汁漏是腹腔镜肝叶切除治疗复杂肝内胆管结石术后发生肝断面感染的危险因素(P<0.050),而术中放置双套管是其保护因素(P<0.050)。 结论 对于复杂肝内胆管结石行腹腔镜肝叶切除治疗患者,可针对其术后肝断面感染的相关危险因素加强术前管理和术中精细操作进行预防,若术后发生了肝断面感染应采取积极有效的治疗策略。

Objective To explore risk factors and treatment strategies of liver resection surface infection following laparoscopic hepatolithiectomy for patient with complicated intrahepatic bile duct stones. Methods The clinical data of 45 patients with complicated intrahepatic bile duct stone underwent laparoscopic hepatectomy from January 2014 to April 2017 in this hospital were analyzed. The liver resection surface infection rate, pathogenic bacteria distribution, factors of operation, antibiotic use time, volume of drainage, and tube placement time were analyzed. Results A total of 13 cases of liver resection surface infection occurred following aparoscopic hepatolithiectomy in the 45 cases, the infection rate was 28.89%. Totally 24 strains of pathogens were isolated from the infected patients, including 9 strains of gram-positive bacteria and 15 strains of gram-negative bacteria. The mainly postoperative complications included 16 cases of biliary fistula, 5 cases of effusion and empyema, the average drainage volume was about 200 mL after surgery. The double pipe were placed in the 10 patients during intraoperation. The drainage tubes were placed in the 23 patients under the ultrasound or CT intervention after the surgery, the average time of drainage tube placement was 8 d. The results of univariate analysis showed that past biliary surgery, combined with liver cirrhosis, double pipe drainage, operation time and postoperative bile fistula were associated with the liver section surface infection following laparoscopic hepatolithiectomy (P<0.05). The results of multivariate analysis identified that the past biliary surgery and postoperative bile fistula were the risk factors, while the double pipe drainage was the protective factor for liver resection surface infection following laparoscopic hepatolithiectomy. Conclusions Prophylactic treatment such as perfect preoperative management and careful intraoperation should be taken for risk factors of liver section surface infection following laparoscopic hepatolithiectomy. Actively effective treatment strategies should be given if postoperative liver section infection existence.
