Background:Robotic surgery can help to identify and preserve the autonomic nerves during total mesorectal excision (TME) compared with open surgery or laparoscopy due to the 3-dimensional image and high dexterity of the robotic system. Therefore, this study aimed to assess voiding and sexual function after robotic TME with autonomic nerve preservation. In particular, we focused on the long-term results in male patients operated by a single experienced surgeon.Materials and Methods:We surveyed male patients aged 50 years and below at the time of robotic rectal cancer surgery between November 2011 and July 2018. Patients who died and those who had a recurrence and underwent abdominoperineal resection were excluded. The questionnaire covered the International Prostate Symptom Score (IPSS) and the 5-item version of the International Index of Erectile Function (IIEF-5) for voiding and sexual function, respectively.Results:Thirty-nine patients (median age, 44 y) were surveyed. IPSS and IIEF-5 scores were 5.7±5.3 and 14.7±8.4, respectively. Only 6 patients (15.4%) complained of poor quality of life due to their urinary symptoms. In sexual function, 10 patients (25.6%) complained severe reduction compared with their preoperative status. The average of postoperative days defined from surgery to the questionnaire was 37.8 months. A significant change in the IIEF-5 score was observed between 1 and 2 years postoperatively (5.8±6.9 vs. 16.5±8.8; P=0.027).Conclusions:As we only included male patients who were operated by a single experienced surgeon, the results of robotic TME with pelvic autonomic nerve preservation showed acceptable data in preserving both voiding and sexual functions. Although related clinical factors for poor functional outcomes was not statistically significant due to the small sample size, we could observe an improvement in sexual function between 1 and 2 years after surgery with long-term functional results.
