Brief Summary

Endometriosis is a chronic disease defined as the existence of endometrium like lesions outside of the uterine cavity. The diagnosis is based on examination of lesions under the microscope and capturing endometrial gland and stroma. The mostly used surgical technique to diagnose and treat endometriosis is laparoscopic surgery. In our novel technique for endometriosis surgery, we used methylene blue for its natural blue color to make endometriotic lesions more visible and to filter red, yellow and white colors reflecting from the peritoneal surface.
