Summary

This trial will test whether a preoperative 10-day bowel regimen of PEG daily can improve postoperative bowel function after minimally invasive hysterectomy.

Who is the study for?
This trial is for women aged 18 or older who are about to have minimally invasive hysterectomy surgery and can understand the consent process. It's not for those who regularly use laxatives, have swallowing difficulties, bowel obstructions, certain medical conditions like chronic kidney disease or insulin-dependent diabetes mellitus, or are having emergency surgery.
What is being tested?
The study tests if taking a bowel-cleaning agent called Polyethylene Glycol (PEG) 3350 daily for 10 days before surgery improves postoperative bowel function in women undergoing minimally invasive hysterectomy compared to no preoperative regimen.
What are the potential side effects?
Polyethylene Glycol is generally well-tolerated but may cause side effects such as bloating, gas, upset stomach, dizziness or increased thirst. Severe allergic reactions are rare.
