This video demonstrate laparoscopic surgery for ovarian dermoid performed by Dr R K Mishra at World Laparoscopy Hospital. They can cause torsion (twisting), infection, rupture, and cancer. These dermoid cysts can be removed with either conventional surgery or laparoscopy (surgery that uses small incisions and specially designed instruments to enter the abdomen or pelvis). We conclude that the risk of chemical peritonitis can be minimized when undertaking laparoscopic removal of ovarian dermoid cysts if the peritoneal cavity is washed out thoroughly from spillage of cyst contents. Drainage of peritoneal cavity should be performed in the patients with the ruptured dermoid cysts.
