目的比较腹腔镜下左半肝切除与左肝外叶切除治疗左肝内胆管结石的效果。方法回顾性分析鄞州医院2011年6月~2016年1月收治的腹腔镜手术治疗左侧肝内胆管结石患者45例,其中腹腔镜左外叶切除24例,腹腔镜左半肝切除21例,比较两组的手术时间...目的比较腹腔镜下左半肝切除与左肝外叶切除治疗左肝内胆管结石的效果。方法回顾性分析鄞州医院2011年6月~2016年1月收治的腹腔镜手术治疗左侧肝内胆管结石患者45例,其中腹腔镜左外叶切除24例,腹腔镜左半肝切除21例,比较两组的手术时间、术中出血、并发症、住院时间、术后残石率和结石复发率。结果两组间的术中出血量(P=0.861)、手术时间(P=0.097)、并发症(P=0.792)、住院时间(P=0.672)、及术后结石残留率(P=0.677)均无统计学差异,腹腔镜左半肝切除组的结石复发率低于腹腔镜左肝外侧叶切除组,但亦无统计学差异(0 vs 8.33%,P=0.738)。结论腹腔镜左半肝切除治疗左侧肝内结石并未增加手术风险,是安全有效可行的。展开更多
