Background: To compare the clinicopathological and cosmetic outcomes of robotic colectomy using the da Vinci SP and Single-Site for left-sided colon cancer.

Methods: The study included 31 and 52 patients who underwent robotic colectomy using the SP and Single-Site, respectively, between July 2011 and July 2023. The Patient Scar Assessment Questionnaire (PSAQ) was used to assess cosmetic outcomes.

Results: Patients who underwent colectomy using the SP had a shorter wound length, less bleeding, and fewer port usages compared with those who underwent colectomy using the Single-Site. The SP group required fewer analgesics on post-operative day 2, showed a shorter time to flatulence, sip water and soft diet, and a shorter hospital stay. Total PSAQ scores for the SP group were superior to those of the Single-Site group.

Conclusions: Robotic colectomy for left-sided colon cancer using the SP presents better short-term recovery, requires fewer analgesics and has better cosmetic outcomes than Single-Site.

背景： 比较使用达芬奇SP和Single-Site机器人进行左半结肠癌根治术的临床病理和美容效果。

方法： 本研究纳入了2011年7月至2023年7月期间，分别采用SP和Single-Site机器人进行机器人辅助结肠切除术的31名和52名患者。使用《患者疤痕评估问卷》（PSAQ）来评价美容效果。

结果： 与使用Single-Site组相比，使用SP组的手术切口长度更短、出血量较少且穿刺次数更少。术后第2天，SP组需要的止痛药用量更少，并表现出更快恢复排气、饮水和软食的能力以及更短的住院时间。总体PSAQ评分显示SP组优于Single-Site组。

结论： 使用达芬奇SP机器人进行左半结肠癌根治术具有更好的短期恢复效果，需要较少止痛药并且美容效果更好。
