Abstract

Aim: This study was performed to clarify the relationship between robotic rectal resection and postoperative ileus (POI) by comparing robotic surgery with laparoscopic surgery. Materials and Methods: We retrospectively reviewed 238 patients who underwent robotic (n=41) or laparoscopic (n=197) rectal resection for rectal cancer in our institution from January 2013 to June 2020. First, we compared the background factors and short-term surgical outcomes between robotic and laparoscopic surgery. Next, we investigated the postoperative complications of robotic and laparoscopic rectal resection. Finally, we identified the risk factors for POI following rectal cancer resection. Results: The percentages of patients with an Rb tumor location, treatment by abdominoperitoneal resection/intersphincteric resection/low anterior resection, a temporary diverting ileostomy, and a long operation time were significantly higher in robotic than laparoscopic surgery (P<0.0001, P=0.0002, P=0.0078, and P=0.0001, respectively). There was no significant difference in any individual postoperative complication between robotic and laparoscopic surgery. Risk factors for POI were male sex (P=0.0078), neoadjuvant chemoradiotherapy (P=0.0007), an Rb tumor location (P=0.0005), treatment by abdominoperitoneal resection/intersphincteric resection/low anterior resection (P=0.0044), a temporary diverting ileostomy (P<0.0001), and operation time of ≥240 minutes (P=0.0024). Notably, robotic surgery was not a risk factor for POI following rectal resection relative to laparoscopic surgery. Conclusion: Although patients who underwent robotic surgery had more risk factors for POI, the risk of POI was similar between robotic and laparoscopic rectal resection.
