胸腹腔镜食管癌切除术学习曲线分析 陈焕文 杜铭 吴庆琛 王显平 唐文风 赖光湖 【摘要】目的：探讨胸腹腔镜食管癌切除术学习曲线。方法：分析2009年9月至2010年12月由作者本人完成的38例胸腹腔镜食管癌切除术。按手术先后次序分4组(A、B、C、D)，每组约10例，比较各组手术时间、术中出血量、淋巴结清扫总数、中转开胸率、并发症。结果：各组手术时间术中出血量虽然有下降趋势，但是没有统计学意义(P0．05)。无中转开腹，中转开胸率、淋巴结清扫个数，术后并发症率差异没有显著意义。而前两组（A组+B组）手术时间、术中出血量和后两组（C组+D组）手术时间、术中出血量有统计学差异(P均0．05)。结论：无胸腹腔食管癌切除经验医师完成胸腹腔镜食管癌切除术的学习曲线大约为20例。 【关键词】 学习曲线；胸腔镜;腹腔镜 【中图法分类号】 【文献标志码】 A The learning curve of Esophagectomy With thoracoscopy and laparoscopy for esophageal carcinoma .
