Obstructive defecatory syndrome (ODS) or inability to completely empty bowel is characterized by a combination of straining, incomplete evacuation, and the use of digital manipulation with bowel movement. This is a common condition with estimated incidence of 15-20% in the adult female population. Laparoscopic abdominal ventral rectopexy is an established surgical technique aimed at restoring rectal support in women with this condition. It is the most common surgery used nowadays to treat ODS. Transvaginal sacrospinous rectopexy, is an innovative procedure which has been shown to be safe and effective in the treatment of stool entrapment. Currently it is unknown whether one of the procedures mentioned is superior to the other regarding surgical outcomes and patient experience. The purpose of this research is to compare the outcomes of these two procedures considering their efficacy to improve symptoms. During the study, participants will be randomized to undergo one of two procedures for treatment of inability to completely empty their bowel and/or rectal prolapse: 1) laparoscopic abdominal ventral rectopexy; 2) transvaginal sacrospinous rectopexy. Following the procedure, participants will be asked to return to the office for a follow-up visit 2-weeks, 2-, 12- and 24-months after the surgery. During each follow-up visit participants will undergo symptom evaluation, pelvic exam and transvaginal pelvic ultrasound to evaluate surgical success.

| Type | Measure | Description | Time frame | Safety issue |
|---|---|---|---|---|
| Primary | Degree of rectal hypermobility | The degree of rectal hypermobility measured via ultrasound (i.e. compression ratio). | 24 months post-operatively | |
| Secondary | Postoperative pain by pain scale | Participants will complete the Pain Scale. No pain will indicate the best outcome whereas the most intense pain imaginable will indicate the worst outcome. | 24 months post-operatively | |
| Secondary | Postoperative pain by an assessment of pain medication use | Participants will be asked to indicate whether or not they are taking pain medication. | 24 months post-operatively | |
| Secondary | Postoperative functional activity level | Participants will complete the Activity Assessment Scale which measures functional activity. The activity level will be measured on a scale of no difficulty, a little difficulty, some difficulty, a lot of difficulty, not able to do it, and did not do it for other reasons. | 24 months post-operatively | |
| Secondary | Global improvement in bladder function | Participants will complete the Patient Global Impression of Improvement. The improvement will be measured on a scale of very much better, much better, a little better, no change, a little worse, much worse, and very much worse. | 24 months post-operatively | |
| Secondary | Pelvic Organ Prolapse Distress Inventory (POPDI) | As a part of the pelvic floor distress inventory (PFDI) questionnaire, participants will complete the POPDI. The symptoms will be measured on a scale of 0, present, to 4, quite a bit. A higher score will indicate a higher symptom burden. | 24 months post-operatively | |
| Secondary | Colorectal-Anal Distress Inventory (CRADI) | As a part of the pelvic floor distress inventory (PFDI) questionnaire, participants will complete the CRADI. The symptoms will be measured on a scale of 0, present, to 4, quite a bit. A higher score will indicate a higher symptom burden. | 24 months post-operatively | |
| Secondary | Urinary Distress Inventory (UDI) | As a part of the pelvic floor distress inventory (PFDI) questionnaire, participants will complete the UDI. The symptoms will be measured on a scale of 0, present, to 4, quite a bit. A higher score will indicate a higher symptom burden. | 24 months post-operatively | |
| Secondary | Pelvic floor Impact Questionnaire (PFIQ) | Participants will complete PFIQ, a condition-specific health-related quality of life questionnaire. The measurement will be on a scale of 0, not at all, to 3, quite a bit. Higher scores indicate greater impact. | 24 months post-operatively | |
| Secondary | Short Form 36 Health Survey Questionnaire (SF-36) | Participants will complete SF-36 which measures eight scales: physical functioning (PF), role physical (RP), bodily pain (BP), general health (GH), vitality (VT), social functioning (SF), role emotional (RE), and mental health (MH). Higher scores indicate better health status. | 24 months post-operatively | |
| Secondary | EuroQol-5D (EQ-5D) | Participants will complete EQ-5D, an instrument that evaluates quality of life on five dimensions: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. The measurement will be on a scale of 1 to 5. | 24 months post-operatively | |
| Secondary | Brink Scale | Participants will complete the Brink Scale, a digital assessment of pelvic floor muscle strength. It consists of 3 separate 4-point rating scales for pressure, vertical finger displacement, and duration. | 24 months post-operatively |
