Background Laparoscopic total mesorectal excision (LapTME) is a validated technique for the treatment of rectal cancer. However, the ergonomic limitations of pure laparoscopy could lead to high conversion rates and a high rate of autonomic disorders. For these reasons the robot-assisted TME (RobTME) has been proposed to overcome the limitations of LapTME. The aim of this study is to compare surgical outcomes, medium-term oncologic results, and postoperative autonomic function of LapTME versus RobTME, in a single surgeon experience. Patients and Methods The first 26 LapTME were compared with the first 26 RobTME performed by a single surgeon between January 2009 and May 2013. Perioperative outcomes were prospectively collected and compared. The impact of minimally invasive TME on autonomic function and quality of life (QOL) was analyzed with the ICIQ-FLUTS and the ICIQ-MLUTS (International Consultation on Incontinence–Male/Female Lower Urinary Tract Symptoms) and IIEF (International Index of Erectile Function)/FSFI (Female Sexual Function Index) questionnaires. Pathological aspects and oncological outcomes were also collected. Results Of the 26 LapTME, 22 were anterior resections (ARR), 2 intersphincteric resections (ISR), and 2 abdominoperineal resections (APR), while of the 26 RobTME, 17 were ARR, 5 ISR, and 4 APR. Mean operative time was significantly higher (p<0.001) while conversion rate to hand-assisted or open surgery was significantly lower in the robTME group (p<0.05). There were no significant differences in sexual and urinary scores between the two groups before surgery and at 1 year after surgery. There were no differences in 3 year overall survival, disease free survival, and recurrence rate as well as the other parameters analysed. Conclusion RobTME is a safe and effective technique and the results compare favourably to the results obtained with laparoscopic procedures. It seems a promising alternative to preserve autonomic function and results in a low conversion rate even when used for more high risk procedures such as ISR or APR.

Abstract
Background Laparoscopic total mesorectal excision (LapTME) is a validated technique for the treatment of rectal cancer. However, the ergonomic limitations of pure laparoscopy could lead to high conversion rates and a high rate of autonomic disorders. For these reasons the robot-assisted TME (RobTME) has been proposed to overcome the limitations of LapTME. The aim of this study is to compare surgical outcomes, medium-term oncologic results, and postoperative autonomic function of LapTME versus RobTME, in a single surgeon experience. Patients and Methods The first 26 LapTME were compared with the first 26 RobTME performed by a single surgeon between January 2009 and May 2013. Perioperative outcomes were prospectively collected and compared. The impact of minimally invasive TME on autonomic function and quality of life (QOL) was analyzed with the ICIQ-FLUTS and the ICIQ-MLUTS (International Consultation on Incontinence–Male/Female Lower Urinary Tract Symptoms) and IIEF (International Index of Erectile Function)/FSFI (Female Sexual Function Index) questionnaires. Pathological aspects and oncological outcomes were also collected. Results Of the 26 LapTME, 22 were anterior resections (ARR), 2 intersphincteric resections (ISR), and 2 abdominoperineal resections (APR), while of the 26 RobTME, 17 were ARR, 5 ISR, and 4 APR. Mean operative time was significantly higher (p<0.001) while conversion rate to hand-assisted or open surgery was significantly lower in the robTME group (p<0.05). There were no significant differences in sexual and urinary scores between the two groups before surgery and at 1 year after surgery. There were no differences in 3 year overall survival, disease free survival, and recurrence rate as well as the other parameters analysed. Conclusion RobTME is a safe and effective technique and the results compare favourably to the results obtained with laparoscopic procedures.
