Male sexual function after laparosco-pic and laparotomye section in patients with lower rectal cancer / 实用医学杂志

ABSTRACT

Objective To investigate the effects of laparoscopic and open resection with pelvic autonomic nerve preservation (PANP) on sexual function of male patients with lower rectal cancer. Methods Total 177 male patients with lower rectal cancer received surgery from September 2008 to December 2013 were enrolled into two groups: the laparoscopic PANP group (n = 105) and the open PANP group (n = 72). The classifications of erectile and ejaculatory functions were used to evaluate the sexual functions of patients at 6 months and 12 months post-operation, respectively. The effect of different operation on the sexual function of the male patients was compared between the two groups. Results The incidence rates of erectile dysfunction at 6 months and 12 months post-operation in the laparoscopic group were lower than those in the laparotomy group (P < 0.05). The incidence rates of ejaculatory dysfunction at 6 months and 12 months post-operation in the laparoscopic group were also lower than those in the laparotomy group (P < 0.05). Conclusion The laparoscopic resection with PANP in patients with lower rectal cancer can not only clearly reveal pelvic autonomic nerve and effectively protect them, but also reduce the incidence of postoperative sexual dysfunction.
