单切口腹腔镜手术(SILS)作为一项新的微创技术,常用于治疗良性结直肠疾病,但其在治疗结直肠癌方面的经验很少。因此,研究者纳入了68例行SILS切除术的结直肠癌患者作为研究对象,并与行传统手术的结直肠癌患者进行比较:比较两组患者的淋巴结清扫数目、标本长度和手术时间。结果显示:两组的环周切缘阳性例数以及肿瘤距切缘距离的差异无统计学意义,但是纳入患者中出现的2例环周切缘阳性者均仅出现在SILS手术组,而传统手术组无该类案例出现;SILS术后住院时间 Single-incision laparoscopic surgery (SILS), a new minimally invasive technique commonly used in the treatment of benign colorectal disease, has little experience in the treatment of colorectal cancer. Therefore, the researchers enrolled 68 patients with colorectal cancer who underwent SILS resection and compared them to colorectal cancer patients undergoing conventional surgery: The number of lymph node dissections, specimen length, and duration of surgery were compared between the two groups. The results showed that there was no significant difference between the two groups in the number of positive peripheral margins and the distance from the margins of the margins in the two groups. However, two cases of positive peripheral margins were included in the SILS group only, There was no such case in the operation group; hospital stay after SILS
