Patient: Description (onset, main symptoms, hospital visited, etc.): The left thyroid swelling was found 3 years ago, no pain, no fear of heat, excessive sweating, no hyperphagia, no weight loss, no palpitations, no blindness, no dreams, no treatment, no significant enlargement of the swelling. He had an ultrasound examination, which indicated that “cystic thyroid adenoma on the left side with clear borders, envelope, hypoechoic fluid, and no enlargement of surrounding lymph nodes”. On December 19, 2010, he underwent laparoscopic cholecystectomy, choledochotomy and T-tube drainage for “lower bile duct stone combined with biliary pancreatitis”. After surgery, he was hospitalized again in March 2011 for “recurrent pancreatitis” and was discharged after one month of conservative treatment. So far, there is no significant attack of pancreatitis. (I am also a general surgeon at Maoming People’s Hospital.) I would like to know about my minimally invasive lumpectomy of the thyroid gland. 1. whether an ultrasonic knife or an electric knife is used to remove the tumor during the surgery; 2. what are the chances of damaging the parathyroid glands and the laryngeal nerve; 3. whether the subcutaneous space, the subcutaneous tunnels for entering the mirror and operating instruments during the original surgery will be shrunken and wrinkled after the surgery; 4. how long will the hospital stay be? What is the total approximate cost? Doctor: 1. The surgery is performed with an ultrasonic knife, not an electric knife. 2, the chance of damaging the parathyroid glands and the recurrent laryngeal nerve exists, but we have hundreds of surgical cases here, and none of them have been damaged by the parathyroid glands or the recurrent laryngeal nerve. (We are all personally operated by Director Qiu Ming, so there are few complications). 3.No contraction or wrinkle change in the subcutaneous space and entry channel during the original surgery after the surgery. 4, hospitalization time of about 7 days, the cost is about 15,000.
