Effects Of Pelvic Autonomic Nerve Preservation In Robotic And Laparoscopic Total Mesorectal Excision On Urinary And Sexual Function

Objective: To investigate the feasibility and treatment effect of robotic total mesorectal excision(RTME)and pelvic autonomic nerve preservation(PANP)for rectal carcinoma on postoperative urinary and sexual function.Methods: During the period of Jue.2016 to Sep.2017,in the department of Laparoscopic Gastrointestinal Surgery of the First Affiliated Hospital of Medical University of Anhui,98 cases of patients with rectal carcinoma were selected and they were divided into two groups: robotic group(RTME+PANP)and laparoscopic group(LTME+PANP).Questionnaire survey was used to evaluate urinary ability(IPSS),sexual function(IIEF-15 for males,FIFS-19 for females)during preoperative and postoperative time within one year after operation.To compare the scores of the three scales after operation between the two groups,and to carry out statistical analysis.Result: Group RTME+PANP patients postoperative IPSS score was lower than that in LTME+PANP group,while in the 3 months(10.2±0.6 vs 10.8±1.2)and 6 months(8.2±0.6 vs 8.6±0.5)after the operation,the difference was statistically significant(P<0.05).Group RTME+PANP patients postoperative IIEF-15 score was higher than that in LTME+PANP group,The difference was statistically significant in the 6 months(46.8±6.2 vs 40.4±8.4)and 1 year(52.2±10.9 vs 46.4±8.8)after the operation(P<0.05).Group RTME+PANP patients postoperative FIFS-19 score was all higher than that in LTME+PANP group in the 1 year period after the operation,the differences were dramatically significant(P<0.001).There was no significant difference among the three score in the two groups(P>0.05).Conclusion: RTME+PANP reduces patients' suffering in urogenital dysfunction in the short-term,RTME+PANP improve life quality of female patients to the greatest extent.
