Abstract：
Randomized studies showed that robotic surgery was short-term useful and safe for cancer patients. We investigated whether robots improve deep resection margins or superficial resection margins for radial resection margins in terms of short-term results. From an institutional database, we selected all superficial groups (≤ 3 mm) and deeper groups (≥ 4 mm) with rectal cancer treated with resection for a year. We evaluated the short-term post-operative 90-day outcomes on a radial resection size-based margin differentiation, including the first bowel movement, length of hospital stay, sepsis, and harvested lymph node. The main results were grades III-IV on the Clavien-Dindo scale and complications. We found 120 patients who had oncologic resection of rectal cancer; 42 patients with a superficial radial resection margin of ≤ 3 mm, all the following outcomes improved: the harvested lymph node, proximal resection margin, TME, flatus time, liquid diet duration, anastomotic leakage, and sepsis. Among these advantages were a reduced risk of metastasis and an overall reduction in local recurrence.
摘要：
随机研究表明，机器人手术对癌症患者是短期有用和安全的。我们调查了从短期结果来看，机器人是否可以改善radial骨切除边缘的深切除边缘或浅切除边缘。从机构数据库中，我们选择了所有浅表组(≤3mm)和较深组(≥4mm)接受直肠癌切除术治疗1年.我们评估了基于放射状切除大小的切缘分化术后90天的短期结果，包括第一次排便,住院时间,脓毒症,并收集淋巴结。主要结果为Clavien-Dindo量表的III-IV级和并发症。我们发现120例接受直肠癌肿瘤切除术的患者；42例径向浅切缘≤3mm的患者，以下所有结果均得到改善：收集的淋巴结，近端切除边缘，TME,排气时间,流质饮食持续时间，吻合口漏,还有败血症.这些优势之一是降低了转移风险和局部复发的整体减少。
