Scientific titleA prospective clinical trial of autonomic pelvic nerve damage in women with sexual dysfunction after restorative proctocolectomy with ileal pouch anal anastomosis (IPAA)
Study acronymPlexlab
Study objectivesSexual dysfunction after ileal pouch anal anastomosis (IPAA) is common. The most systematic physical reaction to sexual stimulation is an increase in vaginal vasocongestion. Damage to the autonomic nerves disrupt this process. Genital response can be assessed by vaginal pulse amplitude using vaginal photoplethysmography. To date, little is known about the contribution of damage to the pelvic autonomic nerves. Aim of this prospective study was to assess whether IPAA is associated with autonomic pelvic nerve damage and changes in subjective indices of sexual function in women.
Ethics approval(s)Medische Ethische Commissie approved on the 25th February 2004 (ref: MEC 03/281 # 04.17.0283)
Health condition(s) or problem(s) studiedUlcerative colitis
InterventionDuring sexual stimulation (visual and vibrotactile) changes in vaginal vasocongestion were measured by vaginal photoplethysmography. This is currently the most sensitive, specific and reliable instrument for measuring vaginal vasocongestion. Vaginal pulse amplitude (VPA) fluctuations reflect phasic changes in the blood content of the illuminated capillary bed of the vaginal wall at each heart beat, with greater amplitudes indicating increased vasoengorgement. Concurrently, quality of life (36-item short form health survey [SF-36]) and sexual functioning (Female Sexual Function Index [FSFI], Female Sexual Distress Scale [FSDS]) were assessed using validated questionnaires.
