About

The purpose of this study is to determine a difference in participant reported pain after endometriosis surgery in participants given oral metronidazole versus placebo.

Full description

The study is a prospective, randomized, placebo-controlled trial. Women scheduled for endometriosis surgery between 18-50 years of age will be invited to participate in the study. Participants with surgically staged endometriosis will be randomized to the metronidazole plus routine postoperative care arm or the placebo plus routine postoperative care arm. Participants will take study or placebo drug for a total of 14 days. Participants will complete surveys at baseline and postoperatively at 6 weeks, 6 months, 1 year, 2 years, 3 years, 4 years, and 5 years reporting intensity of endometriosis associated pain on a visual analog scale, pregnancy outcomes, quality of life, and sexual health.
