Objective To study the clinical treatment effects of typical Ivor-Lewis and modified Ivor-Lewis in the treatment of pa-tients with esophagus cancer. Methods 75 patients with esophagus cancer admitted in our hospital between January 2010 and Jan-uary 2015 were selected and divided into research group and control group according to different surgical options. The research group adopted modified Ivor-Lewis and the control group adopted typical Ivor-Lewis. The general operation conditions (time of op-eration, intraoperative blood loss, dissected lymph nodes), postoperative complications and postoperative hospitalization duration of the two groups were observed. Results The operation time of research group and of the control group was (186.2±33.2) min and (232.3±33.9) min, and the difference was statistically significant (P<0.05). The number of mediastinal lymph-nodes dissection in the research group and in the control group was 4.8±4.5 and 18.6±4.2, and the difference was statistically significant (P<0.05). Conclusion For dissection of lymph nodes in middle and inferior mediastinum, the typical Ivor-Lewis is better than modified Ivor-Lewis. However, the modified Ivor-Lewis is easy to operate and can reduce the operation time.%目的：观察经典Ivor-Lewis术与改良Ivor-Lewis术治疗食管癌患者的临床疗效。方法临床纳入该院2010年1月-2015年1月收治的食管癌患者75例，根据入院后手术方案的不同分为研究组与对照组，研究组采用改良Ivor-Lewis术，对照组采用经典Ivor-Lewis术。结果研究组手术时间为（186.2±33.2）min，对照组为（232.3±33.9）min，差异有统计学意义（P<0.05）；研究组纵膈清扫淋巴结（4.8±4.5）个，对照组纵膈清扫淋巴结（18.6±4.2）个，差异有统计学意义（P<0.05）。结论经典Ivor-Lewis术清扫食管中下段癌淋巴结的能力优于改良Ivor-Lewis术，可以应用于管中下段癌患者。而改良Ivor-Lewis术手术操作相对简单，能够缩短手术时间。
