Condition(s) targeted: Post Procedural Constipation

Intervention: MiraLax (Drug); Placebo (Drug); Rescue Laxative (Drug)

Phase: N/A

Summary

A. Purpose To compare MiraLAX versus placebo for preventing constipation in the immediate postoperative period following pelvic reconstructive surgery in women taking routine docusate sodium. B. Objectives 1. Specific Aims Specific Aim 1: To compare time to first bowel movement (BM) between MiraLAX versus placebo in women receiving routine docusate sodium after pelvic reconstructive surgery. Specific Aim 2: To compare patient reported outcomes of BM quality and associated gastrointestinal (GI) symptoms between MiraLAX versus placebo using the Bristol stool scale and the validated Patient Assessment of Constipation Symptom Questionnaire (PAC-SYM) in women receiving routine docusate sodium after pelvic reconstructive surgery. Specific Aim 3: To evaluate GI-related quality of life between MiraLAX versus placebo utilizing the validated Patient Assessment of Constipation Quality-of-Life Questionnaire (PAC-QOL) in women receiving routine docusate sodium after pelvic reconstructive surgery. 2. Hypotheses The investigators hypothesize that MiraLAX will optimally prevent constipation following pelvic reconstructive surgery by decreasing time to first BM, decreasing GI symptoms associated with constipation, and increasing measures of GI-related quality of life, while minimizing the bothersome side effects associated with stimulant laxatives.

Clinical Details

Official title: Double-Blind Randomized Controlled Trial of MiraLAX Versus Placebo to Prevent Constipation Following Urogynecologic Surgery in Women Receiving Routine Docusate Sodium

Study design: Allocation: Randomized, Endpoint Classification: Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor), Primary Purpose: Prevention

Primary outcome: Time to first postoperative bowel movement

Secondary outcome:

Other postoperative medication use

Evaluation of symptoms and quality of life related to constipation

Symptoms of Over-Effectiveness

Evaluation of symptoms and quality of life related to constipation 6-weeks postoperatively

Detailed description: This is a randomized double-blind placebo-controlled clinical trial of MiraLAX versus placebo in women undergoing pelvic reconstructive surgery receiving routine docusate sodium. Subjects will be screened for eligibility during their preoperative visits and once enrolled, they will be randomized to receive MiraLAX or placebo starting on postoperative day (POD) 1 and continuing through POD 5. Subjects will be instructed to stop taking this medication if they experience any diarrhea. Subjects in both arms will be instructed to take milk of magnesia as a rescue laxative if they do not experience a BM by the morning of POD 6. All subjects will be provided a 30 day supply of docusate sodium and be instructed to begin this medication on POD 1.
