目的：经肛门内镜直肠癌根治术是近年来新兴的经自然腔道内镜外科手术。本研究评价该术标本的直肠系膜完整性，以了解该术的根治性。方法：收集经肛内镜直肠癌根治术与传统腹腔镜直肠癌根治术的手术标本，分别分为经肛内镜组（A 组）与传统腹腔镜组（B 组），比较两组大体标本系膜完整性评分及环周切缘状态的差异。结果：36例直肠癌患者标本，A 组16例，B 组20例。大体评分 A 组2级2例、3级14例；B 组2级2 例、3级18例；差异无统计学意义（P＞0.05）。环周切缘检查两组各有2例阳性，差异无统计学意义（11.1%比12.5%，P＞0.05）。结论：从手术标本直肠系膜完整性来看，经肛内镜直肠癌根治术的根治性和腹腔镜直肠癌根治术无明显差异。

Objective:Transanal endoscopic radical resection for rectal cancer has become a novel technique in natural orifice transluminal endoscopic surgery(NOTES)during the recent years. This study aimed to evaluate the completeness of mesorectum in the resected specimen from such procedure as an approach to confirm its oncologic adequacy. Methods:The specimens of transanal endoscopic(group A)and laparoscopic(group B) radical resection for rectal cancer were collected. These specimens were evaluated for completeness of mesorectum and the circumferential margin.Results:A total of 36 specimens( group A,n = 16;group B,n = 20)were collected. Macroscopically,group A consisted of 2 cases of grade 2 and 14 of grade 3 specimens;group B consisted of 2 of grade 2 and 18 of grade 3 specimens,with no statistical difference in the grading(P>0.05). There were two case each in the two groups with circumferential margin positivity(11.1% vs 12.5%,P>0.05). Conclusion:Transanal endoscopic radical resection for rectal cancer can achieve oncologic adequacy as comparable to laparoscopic procedure based on the completeness of mesorectum.
