A hernia specialist repairs hernias through either open surgery or laparoscopic surgery. Open surgery involves making an incision in the skin close to the bulge and repairing it. Laparoscopic surgery involves making minute incisions where devices such as cameras are inserted into the patient's body, as Hernia Resource Center explains.
During laparoscopic surgery, the surgeon inflates the patient's abdomen with gas after making the incisions. He then inserts a camera to give him an internal view of the patient's abdomen by portraying it on television screens. With the help of the camera view and other specialized instruments, the hernia specialist repairs the hernia and releases the gas to deflate the patient's abdomen, as Hernia Resource Center states.
