About this study
Prior to surgery, gynecologists and urogynecologists have routinely prescribed preoperative mechanical bowel preparations in attempts to decrease the risk of infection, while also providing easier bowel manipulation and better visualization during surgery. However, many of these proposed benefits have never been proven, and usage of bowel preparations amongst surgeons remains highly variable. In both the general surgery and gynecology literature, researchers have begun to question the need for the vigorous preparations.
Aside from surgical visualization, urogynecologists have additional concerns about how bowel preparations may impact postoperative bowel function given up to half of women with pelvic floor disorders have baseline constipation and straining is known to impact surgical recovery. Many studies have addressed various postoperative fiber and laxative preparations in attempts to improve postoperative bowel-related symptomatology, but none have specifically looked at preoperative bowel preparations.
This study aims to determine if mechanical bowel preparation prior to minimally invasive sacral colpopexy affects patients' postoperative recovery, specifically related to bowel symptomatology; operative or post-operative complications; surgeons' perceptions of surgical difficulty directly attributed to the bowel; and post-operative return of normal bowel function.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Bowel preparationOther
Also called Magnesium citrate
Subjects randomized to the mechanical bowel preparation arm will be instructed to consume 300cc of magnesium citrate no later than 3PM on preoperative day number one.
No bowel preparationOther
Subjects randomized to no bowel preparation will be instructed to continue a regular diet on preoperative day number one.
| Study group | Role | What they receive |
|---|---|---|
| Bowel Preparation | Other | Women randomized to the bowel preparation arm will be instructed to consume 300cc of magnesium citrate no later than 3PM on preoperative day number one. They will also be placed on a clear liquid diet on preoperative day number one. Receives: Other: Bowel preparation |
| No bowel preparation | Other | Subjects randomized to no bowel preparation will be instructed to continue a regular diet on preoperative day number one. Receives: Other: No bowel preparation |
What is being measured
The primary outcome is the main question the study is designed to answer.
PAC-SYM
Bowel symptomatology and bowel-related discomfort will be assessed with the Patient Assessment of Constipation Symptom Questionnaire (PAC-SYM), a 12-item questionnaire covering three domains: abdominal, rectal, and stool.
Measured: 1 year
Secondary outcomes (3)
Surgeon perception of bowel preparation
Immediately after completing the surgical case, surgeons will complete a 13-item surgeon questionnaire assessing degree of surgical difficulty and how it relates to the bowel. Operative time and consultations will also be recorded as objective measures of surgical difficulty.
Measured: 1 year
Return of normal bowel function
A seven-day bowel diary will be obtained at baseline and in the first week after surgery. This log will include daily assessment of bowel frequency, type of bowel movement using the validated Bristol stool scale, degree of straining, and used of narcotics or laxatives.
Measured: 1 year
Perioperative complications
Complications occurring in both groups will be recorded. These include, but are not limited to infections, bowel obstructions, visceral organ injuries, and readmissions.
Measured: 1 year

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Prior to surgery, gynecologists and urogynecologists have routinely prescribed preoperative mechanical bowel preparations in attempts to decrease the risk of infection, while also providing easier bowel manipulation and better visualization during surgery. However, many of these proposed benefits have never been proven, and usage of bowel preparations amongst surgeons remains highly variable. In both the general surgery and gynecology literature, researchers have begun to question the need for the vigorous preparations.
Aside from surgical visualization, urogynecologists have additional concerns about how bowel preparations may impact postoperative bowel function given up to half of women with pelvic floor disorders have baseline constipation and straining is known to impact surgical recovery. Many studies have addressed various postoperative fiber and laxative preparations in attempts to improve postoperative bowel-related symptomatology, but none have specifically looked at preoperative bowel preparations.
This study aims to determine if mechanical bowel preparation prior to minimally invasive sacral colpopexy affects patients' postoperative recovery, specifically related to bowel symptomatology; operative or post-operative complications; surgeons' perceptions of surgical difficulty directly attributed to the bowel; and post-operative return of normal bowel function.

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Bowel preparation and No bowel preparation in people with Pelvic Organ Prolapse and Prolapse, run by Halina M Zyczynski, MD at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 10 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 9 Jan 2018. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
PAC-SYM (time frame: 1 year). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 9 Jan 2018; AzTrials last refreshed its copy on 7 Nov 2026.
