[Thyroid surgery in Japan].

Recent advances in the field of thyroid surgery include the release of the clinical practice guidelines for thyroid tumors, organization of multicenter collaborative research groups studying rare diseases such as multiple endocrine neoplasia (including hereditary medullary thyroid carcinoma) and anaplastic thyroid carcinoma, and development of surgical skills and devices that play a part in securing patients' safety and satisfaction. Endocrine surgeons are privileged to pose and solve many unanswered questions that are relevant to good clinical practice for patients with surgical thyroid disorders in the future.
