| Scientific title | Is postoperative first pregnancy rate higher after laparoscopic restorative proctocolectomy than after open restorative proctocolectomy? |
| Study objectives | Adhesions to the fallopian tubes are thought to be the main cause of infertility after ileal pouch-anal anastomosis (IPAA) surgery, a so-called 'tubal factor infertility'. Recent studies demonstrated a significant decrease in adhesion formation after laparoscopic abdominal surgery. Based on those study results, our hypothesis is that a higher pregnancy rate will be observed after laparoscopic IPAA compared to open IPAA, due to a reduction in adhesions of the Fallopian tubes |
| Ethics approval(s) | The study protocol was approved by the ethics committee of the University Hospitals of the Catholic University in Leuven, Belgium on 30 November 2010, (B32220109939) In the Netherlands ethics approval is not required for this study design. |
| Health condition(s) or problem(s) studied | Restorative proctocolectomy and pregnancy |
| Intervention | 1. All potential participants will be contacted for consent and thereupon a questionnaire will be sent 2. The questionnaire is developed by the departments of Obstetrics and Gynaecology and the department of Surgery at the Academic Medical Centre and it addresses patients general medical history and their desire for children both before and after IPAA 3. If patients report that there ever was a desire for children, fertility and obstetric history will be inquired after in detail 4. All self-reported patient data will subsequently be verified and completed by checking the available medical records at the hospital of the IPAA 5. Pregnancy is defined as a clinical pregnancy i.e. the presence of a fetus with a heartbeat demonstrated by ultrasound 6. Time to pregnancy is defined as the number of cycles or months between stopping contraceptives until pregnancy occurred, defined as the first day of the last menstrual period 7. Most likely, several patients will report more than one pregnancy, these pregnancies however cannot be considered as independent and therefore only the time to first pregnancy will be used in this study 8. Kaplan-Meier survival curves will be plotted for time to first pregnancy after laparoscopic or open IPAA and will be compared with a log-rank test |
| Intervention type | Procedure/Surgery |
| Primary outcome measure(s) |
Time (months) to first natural pregnancy after IPAA |
| Key secondary outcome measure(s) |
1. Time (months) to any first pregnancy after IPAA, including pregnancies after fertility treatment |
