A minimally invasive surgery called laparoscopy uses a thin, lighted viewing instrument (laparoscope). The laparoscope is inserted into the pelvic area through a tiny incision made in the belly button. This process allows the doctor to look at endometrial tissue in the reproductive area. The laparoscope can also be used to surgically remove endometrial tissue.
On ultrasound, sometimes we can see cysts filled with cloudy fluid within the ovary. These cysts are filled with old blood and known as "chocolate cysts" as the old blood looks a lot like chocolate syrup. If we see these characteristic cysts on ultrasound, we will diagnose endometriosis. Moreover, surgery is required if there is significant pelvic pain. Some advocate removal of cysts if they show signs of growth over time or for cysts larger than 5 centimeters
