经自然腔道内镜技术和单孔腹腔镜技术在结直肠外科手术中的应用

经自然腔道内镜手术（NOTES）和单孔腹腔镜手术（LESS）是当今国际微创外科领域的研究与临床应用热点。NOTES技术尚待进一步的发展．而LESS技术是现阶段最可行的体表“无疤痕”技术。是NOTES技术的过渡阶段。虽然腹腔镜辅助的NOTES结直肠手术和完全的NOTES结直肠手术已经见诸报道．但是该手术目前仍然主要处于动物试验阶段。LESS技术在结直肠手术中的应用已经较为广泛．其可行性已经为较多的文献资料证实．而其是否符合肿瘤根治原则尚需进一步的研究确定。

Application of natural orifice transluminal endoscopic surgery and laparoendoscopic single-site surgery techniques in colorectal surgery

The research on natural orifice transluminal endoscopic surgery （NOTES） and laparoendoscopic single-site surgery （LESS） are current worldwide focuses international areas of minimally invasive surgery. NOTES needs further investigation, and as the most available of no scar techniques, LESS provides a transition. Currently, both laparoscopy- assisted NOTES colorectal resection and totally NOTES colorectal resection have been reported, however, the techniques are still mainly under animal investigation. Multiple LESS colorectal resections have been reported worldwide, and the feasibility has been proved by those reports. What＇s more, whether LESS colorectal resection can fulfil the requirements of radical tumor resection needs further investigation.
