Post Procedural Constipation | MiraLAX Versus Placebo to Prevent Constipation Following Urogynecologic Surgery

Post Procedural Constipation research study

What is the primary objective of this study?

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.

Study Arms

Research studies and clinical trials typically have two or more research arms. An arm is a group of people who receive the same treatment in the study.
