目的    总结经脐单孔腹腔镜胆囊切除术的手术经验及技术改进。方法    回顾性分析首都医科大学附属北京友谊医院2008年5月至2009年12月120例经脐单孔腹腔镜胆囊切除术病人的临床资料。结果    1例（0.8%）因胆囊周围粘连严重中转常规腹腔镜胆囊切除术（4孔）。平均手术时间28～145（58.5±23.7） min，平均术中出血量2～100（15.3±8.6）mL，术后平均住院1.3（1～3）d，除4例出现切口脂肪液化，经换药后愈合外，其余病例伤口愈合良好，瘢痕隐蔽不易发现，美容效果满意。随访1～17个月,无胆漏、出血、胆管损伤、切口疝等严重并发症。
结论    经脐单孔腹腔镜胆囊切除术安全可行，具有“无瘢痕”、恢复快等优势，但是对技术和设备要求较高，必须不断改进，而且须严格选择病例。

Abstract    Objective    To evaluate the outcomes of transumbilical single-port laparoscopic cholecystectomy and review the technique improvement. Methods    From May 2008 to Dec 2009, 120 cases transumbilical single-port laparoscopic cholecystectomy were performed in our hospital. The clinical data and surgical outcomes were retrospectively reviewed. Results    One patient (0.8%) was converted to traditional laparoscopic cholecystectomy (4 ports) due to perigallbladder adhesion. The mean operating time was 58.5±23.7min (28-145min). The mean blood loss was 15.3±8.6ml (2-100ml). The mean postoperative hospital stay was 1.3 (range, 1-3d) days. All the incisions except 4 were healed well and the surgical scar was satisfied and virtually concealed within the umbilicus. No postoperative complications were observed at follow-up 1-17 months. Conclusions    Transumbilical single-port laparoscopic cholecystectomy is feasible when patients were well selected.
