Endocrine Surgery

The American Association of Endocrine Surgeons defines endocrine surgery as "the discipline of surgical management of endocrine disorders including the understanding of the disease process, technical mastery, and comprehensive care of surgical endocrine disease of the neck and abdomen." As such, endocrine surgery is a sub-specialty of general surgery that focuses on both benign and malignant disorders of the thyroid, parathyroid, and adrenal glands. Endocrine surgeons also specialize in the treatment of neuroendocrine tumors of the gastrointestinal tract.

Thyroid

An endocrine surgeon will perform comprehensive management of all types of thyroid nodules, including biopsy, surveillance, and surgery. Conditions that typically require surgery include thyroid cancers, symptomatic goiters, and toxic thyroid nodules. Thyroid conditions that are not effectively controlled medically may also benefit from surgical intervention, including refractory Grave’s Disease.

Parathyroid

Primary hyperparathyroidism is often underdiagnosed and is typically discovered incidentally after detecting a high serum calcium level on routine bloodwork or during workup for osteoporosis. Patients with long standing renal failure are at risk for the development of secondary hyperparathyroidism. Surgery is curative for hyperparathyroidism and can help prevent serious health complications as well as promote bone recovery.

Adrenal Glands

Adrenal gland tumors are often also found incidentally and as such are referred to as "incidentalomas." These tumors when discovered require further testing to determine if they are either hormone producing or malignant. Hormonally active adrenal tumors can have serious health consequences including refractory hypertension or Cushing’s syndrome. These tumors are usually removed laparoscopically and generally only require a one night stay in the hospital.

Gastrointestinal Neuroendocrine Tumors

An endocrine surgeon is uniquely trained to workup and treat neuroendocrine tumors of the gastrointestinal tract. Most commonly, these include small bowel or appendiceal carcinoid tumors. Hormonally active pancreatic neuroendocrine tumors (PNETs) are also treated.
