- Abstract
Aim: The aim of this work was to investigate the risk factors associated with the incidence of sexual dysfunction in patients who underwent robot‐assisted surgery with several treatment options, such as neoadjuvant chemoradiotherapy and lateral lymph node dissection, and clarify the longitudinal course of erectile function in risk groups. Method: A total of 203 male patients who underwent robot‐assisted total mesorectal excision for rectal cancer between 2013 and 2019 were included. The risk factors for erectile and ejaculatory dysfunction as well as the longitudinal course of erectile function were retrospectively investigated in all cohorts and several risk groups, including those who underwent neoadjuvant chemoradiotherapy, lateral lymph node dissection and adjuvant chemotherapy. Erectile dysfunction was assessed using the International Index of Erectile Function and ejaculatory dysfunction was assessed using original questions. The survey was performed preoperatively and at 3, 6 and 12 months postoperatively. Results: Erectile and ejaculatory dysfunction occurred in 46.8% and 15.7% of the patients, respectively. Multivariate analysis showed that neoadjuvant chemoradiotherapy was an independent risk factor for erectile dysfunction. Erectile function recovered longitudinally to the preoperative level overall, as well as in lateral lymph node dissection and postoperative adjuvant chemotherapy subgroups; however, recovery was poor in the neoadjuvant chemoradiotherapy group, even at 12 months postoperatively. Conclusion: Neoadjuvant chemoradiotherapy was found to be a risk factor for erectile dysfunction after robot‐assisted surgery for rectal cancer. Erectile function recovered postoperatively in patients undergoing lateral lymph node dissection; however, those receiving neoadjuvant chemoradiotherapy showed poor recovery, even at 12 months postoperatively.
