Bowel, Urinary and Sexual Function After Laparoscopic Colorectal Surgery

Research Populations: Male patients scheduled for laparoscopic colorectal surgery Study Method: Questionnaire and function tests Hypothesis: A laparoscopic nerve-sparing operation is not inferior to reported open surgery in preserving urinary and sexual function.

There have been some reports that laparoscopically assisted rectal resection is associated with a higher rate of male sexual dysfunction compared with the open approach. But these reports are studied retrospectively. We examine the frequency of bowel, urinary and sexual dysfunction prospectively in patients who received laparoscopic colorectal surgery. We examine before operation, 7 days after, 3 months after, 6 months after and 12 months after operation, by questionnaires (International Index of Erectile Function (IIEF) 、Short Form-8 (SF8)、International Consultation on Incontinence Questionnaire-Short Form(ICIQ-SF)、International Prostate Symptom Score(IPSS)、Gastro-Intestinal Functional Outcome(GIFO)) and function tests (uroflowmetry and US).
