[摘要] 目的 分析新辅助放化疗后行腹腔镜下低位直肠癌保肛术的临床效果。 方法 选取2016年1月～2019年12月60例低位直肠癌患者，采用随机分组法，将研究对象划分A组(n=30)和B组(n=30)，两组均实施新辅助放化疗，A组行开腹手术，B组行腹腔镜下保肛术，比较两组手术指标、保肛率、并发症发生率。 结果 两组患者手术时间差异不显著(P>0.05);B组患者术中出血量少于A组;B组患者保肛率高于A组;B组患者切口感染、肠梗阻、尿潴留、吻合口痿等并发症发生率低于A组，两组之间数据比较差异有统计学意义(P<0.05)。 结论 在低位直肠癌患者中实施新辅助放化疗联合腹腔镜下保肛术，术中出血量少，保肛率高，很少出现并发症。
