The argon beam coagulator can be an effective means of treating the uterus during a myomectomy, a type of laparoscopic surgery designed to remove or reduce the size of swollen muscle cells that can cause uncomfortable pressure in the pelvis and unusually severe, frequent periods. The device is also used during laparoscopic surgery for endometriosis, a condition in which lesions in the area surrounding the uterus can cause pain, excessive bleeding, and reproductive difficulties. When medical personnel fail to follow guidelines regarding the argon beam coagulator's use, potentially serious problems may arise, including difficulty having children and embolisms possibly leading to a heart attack. Surgeons are expected to have the proper training and experience to ensure optimal results during argon beam coagulation.
