影响腹腔镜胆囊切除术胆管损伤的相关危险因素研究

目的：探讨腹腔镜胆囊切除术并发胆管损伤的相关危险因素，以减少胆管损伤的发生率，改善患者预后。方法察看2003年12月至2013年12月在该院行腹腔镜胆囊切除手术的1244例患者的病历及病程记录。对患者性别、年龄、行LC术时间、病理、胆囊壁厚度、术前肝功水平、是否存在胆囊三角解剖异常情况和医师经验等因素与LC并发胆管损伤的相关性进行Logistic回归分析。结果LC手术时间早、急性胆囊炎患者、合并胆囊积液的胆结石患者、胆囊壁厚度大于4mm、胆囊三角解剖存在变异情况和医师经验不足是LC手术并发胆管损伤的高危险因素（P＜0．05）。结论针对LC并发胆管损伤的高危因素，术中采用合理手段降低胆管损伤的发生率，术后积极交流学习增加医师LC术的技巧与经验。

Research on correlated risk factors of bile duct injury induced by laparoscopic cholecystectomy

Objective To explore the correlated risk factors of bile duct injury induced by laparoscopic cholecystectomy ,and to reduce the rate of bile duct injury companied with LC and improved patients condition after LC .Methods One thousand two hun‐dred and forty four patients who had been done the laparoscopic cholecystectomy in our hospital were searched from December 2003 to December 2013 for their case notes .The relationship between rate of bile duct injury induced by laparoscopic cholecystectomy and gender ,age ,time of LC surgery ,pathology ,gallbladder wall thickness ,liver function levels ,the existence of the gallbladder triangle anatomical anomalies and physician experience were analyzed by logistic regression method .Results Logistic regression analysis showed that patients did LC surgery at early time ,with acute cholecystitis ,with gallstones combined effusion ,with gallbladder wall thicker than 4 mm and with gallbladder triangle anatomical anomalies were likely to have bile duct injury induced by LC (P<0 .05) .And doctor′s experience on LC is another important factor as well (P<0 .05) .Conclusion According to the correlated risk factors of bile duct injury caused by laparoscopic cholecystectomy ,methods should be employed to reduce the bile duct injury .And sharing experience between doctors and learning new techniques could be helpful ,too .
