NCT02282943

Brief Summary

The purpose of this study is to compare laser CO2 ablation/excision of Endometriosis (AFS stages 1-3) with excision of endometriosis using the Ethicon Harmonic ACE device. Pain scores at 6 months was the primary outcome, but secondary outcomes assessed pain scores at 1, 3 and 5 years as well as psychological state and quality of life.
