目的：探讨双吻合器技术（DST）在低位直肠癌全直肠系膜切除（TME）保肛术中的应用。方法52例低位直肠癌保肛患者，24例应用传统手术治疗（传统组），28例应用DST治疗（DST组）。对两组患者的平均手术时间、术中失血量、住院天数、吻合口瘘、排尿、性功能、局部复发率及术后1年生存率进行统计分析。结果两组手术时间、术中失血量、局部复发率、泌尿功能障碍及性功能障碍的差异有统计学意义（P＜0．05），住院天数、术后并发症及1年生存率差异无统计学意义（P＞0．05）。结论应用DST技术配合TME治疗低位直肠癌，其手术时间短、出血少、并发症少、局部复发率低，可有效保存肛门功能，是治疗低位直肠癌的首选技术。

Objective To evaluate the role of double stapling technique (DST)in anal sphincter preservation surgery by total meso-rectal excision (TME)in low colorectal cancer.Methods A total of 52 cases of low rectal cancer patients underwent anus preserving surgery were selected,among whom there were 24 cases with application of traditional surgical treatments (conventional group)and 28 cases of double stapling technique in the treatment (DST group).The average operative time,intraoperative blood loss,length of stay in hospital,anastomotic leak,urination,sexual function,postoperative local recurrence rate,and 1-year survival rates for both groups of patients were statistically ana-lysed.Results The mean operative time,intraoperative blood loss,the local recurrence rate,urinary dysfunction,and sexual dysfunction had statistically significant difference between conventional group and DST group (P<0.05 ).There was no statistical significant difference in hospitalization days,the postoperative complications and 1-year survival rate in both groups (P>0.05 ).Conclusion Application of DST technology with TME in low rectal cancer treatment has shorter operative time,less blood loss,fewer complications,lower local recurrence rate, long survival time and it can effectively preserve anal function,thus it is a preferred choice for the treatment of low rectal cancer.
