- Scientific TitleRecovery after hysterectomy: A study into influencing factors.
- ACRONYMHysterectomy&CPSP
- hypothesisPrimary Objective:
The identification of (somatic and psychological) risk and protective factors for postoperative recovery, including the development of chronic post operative pain (CPSP), defined as persistent pain 3 and 12 months after the intervention.

Secondary Objective(s):
1. Determination of the prevalence of CPSP after hysterectomy;
2. Determination of the prevalence of sexual dysfunctions after hysterectomy;
3. The identification of risk and protective factors for sexual dysfunctions after hysterectomy;
4. Exploration of the mechanisms (behavioural, cognitive, biological) of CPSP.

- Brief summaryThe prevalence of chronic postoperative pain (CPSP) after hysterectomy ranges from 5 up to 32%.
Etiologic/prognostic research on postoperative recovery traditionally focussed on surgical and anesthesiological factors.

This prospective, observational, multicenter study aims to assess influencing factors for postoperative recovery in a wider perspective.
Apart from somatic factors the interaction between genotype and psychological factors like optimism and resilience will be assessed. Whether surgical intervention leads to epigenetic changes will be studied as well. Finally, the effect of the immunologic response on recovery will be studied.

Primary outcome measure:
Chronic postsurgical pain.

Secondary outcome:
Physical and psychological recovery, sexual functioning.

500 woman (18-65 years) undergoing elective hysterectomy for benign indication.
Baseline data 1 week before surgery, data during hospital stay day 0-4.
Follow-up at 3 and 12 months postoperative.
