经肛门直肠镜下的微创外科技术在直肠癌治疗中的应用

The application of transanal endoscopic microsurgery in rectal cancer treatment

经肛门直肠镜下的微创外科(transanal endoscopic microsurgery,TEM)不仅是经肛切除直肠肿瘤的一种新方法,而且是一种可切除低位、中位和高位直肠的微创技术。和传统的经肛切除相比,TEM暴露的视野更大,复发率更低,并发症更少,具有更好的精准切除等优点。而且对于一些病例来说比开腹或腹腔镜和低位前切除更有效。在严格的病例选择和准确的术前分期的前提下,TEM是一种安全的、可重复的治疗低风险的T1期肿瘤技术。本文介绍了TEM在直肠癌治疗中的应用。

TEM is not only an additional tool for transanal resection of rectal tumor, but also a minimally invasive technique for treating tumors in the low, middle, and upper rectum.Compared with conventional transanal resection,TEM provides superior tumor exposure higher in the rectum,a lower local recurrence rate and a lower complication rate.With strict patient selection and precise preoperative staging, the use of TEM for the treatment of low-risk T1 carcinoma is a safe and reproducible technique.
