- InterventionsCohort 1 (European Cohort): Laparoscopic Ventral Rectopexy;
Cohort 2 (US Cohort): Laparoscopic Resection Rectopexy.
- Primary outcomeImprovement of Quality of life, objectified by the Gastro-intestinal Quality of life Index (GIQLI).
- Secondary outcome1. To evaluate the optimal surgical strategy for laparoscopic rectal prolapse surgery in terms of improving constipation and incontinence (questionnaire, validated scoring systems: Cleveland Clinic Incontinence Score and Cleveland Clinic Constipation Score);
2. To evaluate and compare post-operative morbidity measured by reoperations, reinterventions, re-admissions and serious adverse events;
3. To evaluate the best surgical technique for rectal prolapse in terms of anatomic recurrence of the prolapse, measured by defecogram in rest and during Valsava manouvre;
4. To evaluate the rate of rectal prolapse recurrence and complications (complaints, physical examination, additional research, re-operation and readmission);
5. To evaluate pelvic floor function pre- and postoperatively (questionnaire);
6. To evaluate urogenital functioning pre- and postoperatively (questionnaire and urinary diary);
7. To evaluate quality of life pre- and postoperatively (faecal incontinence, obstructed defecation, voiding and quality-of-life scoring systems);
8. To evaluate length of hospital stay, peri-operative and post-operative in-hospital mortality and morbidity;
9. To evaluate the rate of extra outpatient visits because of complaints.
- TimepointsFollow-up will be performed on the following moments:
1. 3-6 months after operation;
2. 12 months after operation;
3. 24 months after operation.

- Brief summaryBackground:
Rectal prolapse (RP) is the descent of the upper rectum and is a common problem in the western world. Surgery is the only definite treatment and is preferably performed minimally invasive. High-level prospective studies on treatment strategies for RP currently are lacking and, thus, no consensus exist regarding the optimal treatment for patients with RP. Furthermore, remarkable transatlantic differences exist, as in Europe, laparoscopic ventral rectopexy (LVR) is regarded the treatment of choice, while in the USA Laparoscopic Resection Rectopexy (LRR) remains the golden standard.

To determine the optimal minimally invasive surgical treatment for patients with RP.

International, prospective, comparative double cohort study. The first cohort will consist of 120 European patients with a RP and will be treated with LVR. Centres in The Netherlands, Belgium and the UK are enlisted for participation. The second cohort will consist of 120 American patients with a RP, treated with LRR. Several US centres are enlisted. Pre-operative work-up consists of radiological imaging and standardised questionnaires. Follow-up (FU) is set on two years. During FU, pre-operative imaging and questionnaires will be repeated.

Primary & secondary outcomes:
Primary endpoint will be improvement on the Gastro-Intestinal-Quality-of-Life-Index (GIQLI). Secondary endpoints will be generic Quality-of-Life, functional results, morbidity, mortality, recurrences and cost-effectiveness.

Time frame:
Study and inclusion start will be on January the 1st, 2011 and will take approximately 18-24 months. Therefore, total study duration will be 42-48 months.
