Brief Summary:

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.

Layout table for study information
Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 116 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Masking Description: The study surgeon is providing clinical care to enrolled subjects, thus masking the surgeon to treatment allocation or subject symptoms is not practical or feasible, other than the allocation concealment prior to surgical randomization. Given the surgical procedure requires a transvaginal or abdominal incision, it is clinically not possible to mask the participant or other research personnel. Every attempt will be made to keep the research coordinator blinded when assessing symptoms via questionnaires during follow-up visits.
Primary Purpose: Treatment
Official Title: Prospective Randomized Controlled Trial Comparing Transvaginal Rectopexy and Ventral Mesh Rectopexy for Obstructed Defecation in Pelvic Organ Prolapse (PROD Trial)
Estimated Study Start Date : May 2024
Estimated Primary Completion Date : June 2027
Estimated Study Completion Date : February 2028

Arm Intervention/treatment
Experimental: laparoscopic abdominal ventral rectopexy Procedure: Laparoscopic abdominal ventral rectopexy
Laparoscopic abdominal ventral rectopexy is an established surgical technique used to restore rectal support in women with obstructive defecatory syndrome (ODS). It is the most common surgery used to treat ODS. It involves a series of small cuts in the abdomen and the use of mesh to hold the rectum in the correct position.

Experimental: transvaginal sacrospinous rectopexy Procedure: Transvaginal sacrospinous rectopexy
Transvaginal sacrospinous rectopexy is an innovative procedure which has shown to be safe and effective in the treatment of stool entrapment. This is a mesh-free and vaginal route procedure.




Primary Outcome Measures :
  1. Degree of rectal hypermobility [ Time Frame: 24 months post-operatively ]
    The degree of rectal hypermobility measured via ultrasound (i.e. compression ratio).


Secondary Outcome Measures :
  1. Postoperative pain by pain scale [ Time Frame: 24 months post-operatively ]
    Participants will complete the Pain Scale. No pain will indicate the best outcome whereas the most intense pain imaginable will indicate the worst outcome.

  2. Postoperative pain by an assessment of pain medication use [ Time Frame: 24 months post-operatively ]
    Participants will be asked to indicate whether or not they are taking pain medication.

  3. Postoperative functional activity level [ Time Frame: 24 months post-operatively ]
    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.

  4. Global improvement in bladder function [ Time Frame: 24 months post-operatively ]
    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.

  5. Pelvic Organ Prolapse Distress Inventory (POPDI) [ Time Frame: 24 months post-operatively ]
    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.

  6. Colorectal-Anal Distress Inventory (CRADI) [ Time Frame: 24 months post-operatively ]
    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.

  7. Urinary Distress Inventory (UDI) [ Time Frame: 24 months post-operatively ]
    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.

  8. Pelvic floor Impact Questionnaire (PFIQ) [ Time Frame: 24 months post-operatively ]
    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.

  9. Short Form 36 Health Survey Questionnaire (SF-36) [ Time Frame: 24 months post-operatively ]
    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.

  10. EuroQol-5D (EQ-5D) [ Time Frame: 24 months post-operatively ]
    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.

  11. Brink Scale [ Time Frame: 24 months post-operatively ]
    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.
