Patient: female, 40 years old, physical examination found thyroid nodules. Color ultrasound showed that the size and shape of the thyroid gland of both lobes were possible, the isthmus was not thick, and the parenchyma had uniform echogenicity, the right lobe of the thyroid gland was a very solid nodule, about 1.6*1.4CM, with clear borders, regular morphology, and a small amount of colored blood flow signals around the edges and in the inner part of the right lobe, and the left lobe of the thyroid gland was a very hypoechoic small nodule, with a diameter of about 0.2 CM, and there were several flat lymph nodes in the cervical region of both lobes, with a large size of about 1.5*0.5 on the right side and about 1.4*0.4CM on the left side, and no abnormal colored blood flow signals. 1.4*0.4CM, the corticomedullary structure was clear, and no abnormal colored blood flow signal was seen. Ultrasound: right lobe thyroid solid nodule left lobe thyroid hypoechoic nodule bilateral neck several flattened lymph nodes show At present, only the color ultrasound, the other examination doctor did not allow to do May I ask: whether there is a surgical indication? Is there any indication for surgery? Do I need to do blood test and puncture? Professor of General Surgery: Thyroid function should also be checked. A puncture biopsy can be performed in hospitals that are able to do so, which can help to clarify the scope of the surgery beforehand. Patient: Thank you. Do you mean that this nodule should be removed? In your experience, what does it look like? An adenoma? Or something else? Professor of General Surgery: Oh, yes, I mean it should be done. Generally, surgery is recommended for thyroid nodules larger than 1cm. Surgery not only removes the nodule, but also removes the heart disease, right? As you described, according to our clinical experience, benign possibility is high. Patient: Thank you for responding to my question so late in the evening, indeed this has become a heart disease. What I am worried about now is that if I have surgery, how do I have to remove it in my case? Will it cause hypothyroidism? Will it cause hypothyroidism? And if there are any internal adhesions after the surgery, will this cause any problems with future ultrasounds? Will it be more difficult to perform a second surgery if the remaining portion still has nodules in the future? Professor of General Surgery: Generally, the thyroid gland with lumps is removed and the surgery is completed if the lumps are benign. This does not cause hypothyroidism. The local trauma caused by the surgery, including adhesions, has little effect on the appearance and subsequent examination. Although there is a possibility of secondary surgery, the percentage is very small, so there is no need to worry too much. Patient: I checked thyroid function 2, thyroid function 3, and thyroglobulin, and they were all within normal values. The doctor suspects nodular goiter? It is suggested that we can continue to observe. Some people say that if it is a nodular goiter, the remaining part of the goiter can easily grow after it is removed. Is this true? But your reply has made me less fearful of possible future surgeries, thank you so much for your reply.
