Single-Port Versus Multiport Robotic Right Colectomy: Short-Term Outcomes and Impact of Extraction-Site Location on...

Robotic right hemicolectomy has been widely adopted, but the impact of extraction-site location on postoperative pain in single-port (SP) surgery remains unclear. We aimed to compare short-term outcomes between SP and multiport robotic surgery and to evaluate postoperative wound pain according to extraction-site location.

This retrospective single-center study included 49 consecutive patients who underwent robotic right hemicolectomy (January 2024-December 2025): 25 in the SP group and 24 in the Xi group. Postoperative pain was assessed using the cumulative pain score (sum of daily maximum NRS values, POD1-POD7). Pain outcomes were compared among SP_P (Pfannenstiel, n = 13), SP_Umb (umbilical, n = 12), and Xi_P (Pfannenstiel, n = 22).

Perioperative and oncological outcomes were comparable between the groups. The SP group had significantly shorter operative time (244 vs. 309 min, p = 0.0013) and console time (167 vs. 239 min, p = 0.0014). Postoperative pain differed significantly among the three subgroups (p = 0.0049). Pairwise comparisons showed significantly lower pain in SP_P than in SP_Umb (p = 0.0062), with no significant difference for the other two comparisons. The difference between SP_P and SP_Umb remained significant after adjusting for anastomotic technique and surgical procedure in multiple regression analysis.

SP-assisted right hemicolectomy was safe, with short-term outcomes comparable to the Xi platform. These findings suggest that postoperative pain following robotic right hemicolectomy may be influenced not only by the number of abdominal ports but also by the location of the extraction incision.
