This video shows Laparoscopic Endometrioma Surgery by Dr. R.K. Mishra at World Laparoscopy Hospital. The endometrioma is endometriosis of ovary. Endometriosis is the inner lining of the uterus; it is where a fertilized egg will implant during the early days of pregnancy. The endometrium normally sheds during each menstrual cycle if the egg released during ovulation has not been fertilized. Endometriosis is a condition that occurs when cells from the endometrium begin growing outside the uterus. The outlying endometrial cells respond to the hormones that control the menstrual cycle, bleeding each month the way the lining of the uterus does. This causes irritation of the surrounding tissue, leading to pain and scarring. For more detail.
