【摘 要】目的：研究探讨预防性末端回肠造瘘在超低位直肠癌保肛手术中的应用价值。方法：选择我院就医的60例直肠癌患者(2017年1月～2018年7月)进行前瞻性研究，随机分为2组各30例，所有患者均实施超低位直肠癌保肛手术治疗，观察组术中还实施预防性末端回肠造瘘，比较两组的手术情况、术后恢复时间、血清炎症因子指标、术后并发症发生率。结果：组间手术时间、术中出血量比较均无统计学差异(P>0.05)，其术后血清炎症因子各项指标、术后吻合口瘘发生率、术后并发症总发生率均低于对照组(P<0.05)。结论：在超低位直肠癌保肛手术中实施预防性末端回肠造瘘可有效抑制术后炎症反应，减少吻合口瘘等并发症的发生，有利于加快患者术后恢复。

    Abstract Objective：To investigate the value of prophylactic terminal ileostomy in anal sphincter preservation for ultralow rectal cancer. METHODS： Sixty patients with rectal cancer (January 2017 to July 2018) who were admitted to our hospital were enrolled in a prospective study.They were randomly divided into two groups of 30 patients.All patients underwent ultra-low rectal cancer anal sphincter surgery. Preventive terminal ileostomy was also performed in the observation group. The operation status ......
