ABSTRACT

Objective To evaluate the effects of laparoscopic radical resection of mid-low rectal cancer on sexual and urinary functions of male patients. Methods The clinical data of 150 patients with mid-low rectal cancer who were admitted to the PLA General Hospital from May 2006 to March 2009 were retrospectively analyzed. Sixty-eight patients were allocated to laparoscopic group and 82 to open group. The incidences of erectile and ejaculatory dysfunction and the short- and long-term urinary dysfunction of patients in the 2 groups were compared seperately at 6 and 12 months after the operation. All data were analyzed using the chi-square test. Results The incidences of erectile and ejaculation dysfunction at 6 months after operation, incidence of ejaculation dysfunction at 12 months after operation, and long-term urinary dysfunction were 15% (10/68), 16% (11/68), 10% (7/68) and 0 in the laparoscopic group, and 22% (18/82), 23% (19/82), 21% (17/82) and 2% (2/82) in the open group, respectively, no significant difference between the two groups was found (x2 = 1. 285, 1. 137, 3. 013, 1.681, P>0. 05). The incidences of erectile dysfunction at 12 months after operation and short-term urinary dysfunction were 7% (5/68) and 4% (3/68) in the laparoscopic group, and 17% (14/82) and 20% (16/82) in the open group, respectively, a significant difference between the two groups was observed (x = 4. 565, 5.930, P <0.05). Conclusion Laparoscopic radical resection of mid-low rectal cancer can reduce the injury of pelvic autonomic nerve and improve the life quality of patients.
