腹腔镜术相对于传统开腹手术,具有创伤小、出血少、腹壁瘢痕小、恢复快、术后可较早接受其他治疗等优点。但由于腹腔镜术者的手不能进入腹腔,从而失去了手的触觉反馈[1],使得术者对于结直肠的良性病变、早期恶性病变的定位以及肠管切除范围的界定存在局限性。术中结肠镜则可部分替代手的功能,对肿瘤切缘进行精确定位,从而使腹腔镜操作获得更为可靠的肿瘤根治性切除[2]。
Compared with the traditional laparotomy, laparoscopy has the advantages of less trauma, less bleeding, less scar on the abdominal wall, faster recovery and earlier treatment after surgery. However, due to laparoscopic hand can not enter the abdominal cavity, thus losing the hand tactile feedback [1], making the surgeon for the benign lesions of colorectal cancer, early malignant lesions localization and scope of bowel resection limitations. Intraoperative colonoscopy can partially replace the hand function, accurate positioning of the tumor margin, so that laparoscopic operation to obtain a more reliable radical tumor resection [2].
