Some people feel a lump in their neck on their own, others are found to have a thick neck by other people, and others are found by a physical exam. The common manifestation is a thyroid nodule found on ultrasound. The ultrasound descriptions vary from single, multiple, calcified, or with blood flow. Some have no blood flow, some are solid, some are cystic, and some are mixed cystic and solid. So how should these nodules be treated? Doctors say different things, some say it’s okay, your nodules are small and don’t need to be done, some say they need to be done, and some say it’s useless to do it and it will come back afterwards. Here I talk about my views based on my years of clinical experience and consensus for the majority of patients to refer to. 1, with thyroid nodules first of all to choose the appropriate examination. At present, the best test is ultrasound. Other tests such as CT, MRI, ECT, etc. are not as good as color ultrasound. But ultrasound is done by people, and the level of the doctor who does it is very important. I don’t need to say much about this. According to my years of clinical experience, the ultrasound level of China Medical University Hospital is the best. We can basically make a general determination of the benignity and malignancy of thyroid nodules based on our ultrasound. For example, nodules with poorly defined boundaries, multiple punctate calcifications (gravel-like calcifications or microcalcifications), and attenuation are suggestive of malignancy. Or lymph nodes with calcification or liquefaction suggesting lymph node metastasis. It can be said that ultrasound is the most important basis for determining whether a thyroid nodule requires surgery. In addition, we should test the thyroid function and inflammation to know whether there is hyperthyroidism, hypothyroidism, Hashimoto’s disease, etc. The first hospital of China Medical University, Department of Anorectal Surgery, Edward Yang 2. With the results of ultrasound and nail function and nail inflammation, we can initially determine whether surgery is needed. The danger of thyroid nodules 1. large nodules can compress the trachea to produce breathing difficulties or compress the esophagus to produce swallowing difficulties 2. can be secondary to hyperthyroidism 3. can be malignant 4. some nodules are difficult to determine the benignity or malignancy before surgery. Some people use the method of puncture has a very low positive rate, even if the intraoperative pathology of some are not confirmed, so I do not advocate fine needle puncture. Surgery is preferable. 3, some people think that multiple nodules are benign and cystic nodules are benign, but this is not true. Some of the multiple nodules may be malignant. We found in the clinic that some malignant nodules are hidden behind benign nodules, some cystic nodules are malignant in the following part of the implementation, and even suspected malignant nodules are benign and preoperative diagnosis of benign nodules intraoperative pathology is malignant. 4, the current thyroid disease is very complex. We often encounter several diseases mixed together in the clinic. For example, a person has nodules, thyroid adenoma, hyperthyroidism, Hashimoto’s disease, and thyroid cancer at the same time. There are also lesions that are multiple, with cancer in both the left and right lobe isthmus. 5. Most of the thyroid cancers at present are differentiated thyroid cancers, mostly papillary carcinoma, with good prognosis. Even if it is thyroid cancer, you do not have to worry about it, as long as timely and standardized treatment is given, you can expect to have long-term survival.
