中低位直肠癌患者新辅助放化疗后行腹腔镜切除与开腹手术疗效比较的开题报告

摘要

目的:比较中低位直肠癌患者新辅助放化疗后行腹腔镜切除和开腹手术的疗效。

方法:选择2015年1月至2019年12月在我院接受治疗的中低位直肠癌患者78例,其中腹腔镜组40例,开腹组38例。两组患者均接受新辅助放化疗,并进行全肠道准备。比较两组患者手术时间、失血量、术后并发症、病理学参数和随访结果等。

结果:两组患者的手术时间和失血量差异无统计学意义(P0.05)。腹腔镜组的术后并发症发生率(10.0%vs.21.1%)和平均住院时间(8.9±1.5vs.11.5±1.4)明显优于开腹组(P0.05)。腹腔镜组的瘤体清缘率(93.8%vs.87.5%)和纵向切缘阴性率(91.4%vs.81.6%)也明显优于开腹组(P0.05)。随访1年,两组患者的总体生存率和无病生存率差异无统计学意义(P0.05)。

结论:中低位直肠癌患者新辅助放化疗后行腹腔镜切除与开腹手术相比,具有术后并发症少、恢复快、手术创伤小的特点,并且病理学参数良好。因此,腹腔镜切除是一种值得推广的治疗手段。
