直肠癌腹腔镜手术的环周切缘阳性率较高,近年来发展起来的机器人手术有望改善患者的预后。为比较机器人手术与腹腔镜手术的治疗效果,D’Annibale A等遵循全直肠系膜切除(TME)原则对100例直肠癌患者施行了微创前切除术,其中50例患者行机器人全直肠系膜切除术(R-TME),另50例行腹腔镜全直肠系膜切除术(L-TME)。比较2种术式的效果。结果显示,R-TME组和L-TME组的中位手术时间分别为270 min和275 min,清扫淋巴结数量分别为(16.5±7.1)枚和 Laparoscopic surgery for rectal cancer with a higher positive rate of circumferential margins, robotic surgery developed in recent years is expected to improve the prognosis of patients. To compare the effects of robotic surgery and laparoscopic surgery, D’Annibale A et al performed minimally invasive anterior resection in 100 patients with rectal cancer following the principle of total mesorectal excision (TME). Fifty patients underwent total mesorectal excision (R-TME) and another 50 cases underwent laparoscopic total mesorectal excision (L-TME). Comparison of two kinds of surgical results. The results showed that the median operation time of R-TME group and L-TME group were 270 min and 275 min, and the number of lymph nodes was (16.5 ± 7.1) and
