Quick Answer
Endocrine surgery is an operation that removes part or all of a diseased hormone-making gland, most often the thyroid, parathyroid or adrenal glands. It treats problems such as thyroid cancer, an overactive gland and adrenal tumors, using small-incision laparoscopic or robotic methods or open surgery; most people stay in hospital at least one night. [1]
What the research says
Surgeon experience matters in thyroid and parathyroid surgery. A systematic review of 33 studies found that surgeons who perform more thyroid and parathyroid operations have fewer surgical and medical complications, shorter hospital stays and lower total costs than lower-volume surgeons. (Bedi et al., Surgical Oncology, 2021) [2]
Small-incision surgery shortens hospital stays for large adrenal tumors. In a meta-analysis of 10 studies (898 patients) with adrenal tumors 5 cm or larger, minimally invasive surgery cut hospital stay by about 3.5 days and blood loss by about 314 mL compared with open surgery, with no significant difference in complications. (Gan et al., International Journal of Surgery, 2022) [3]
Robotic and laparoscopic adrenal surgery have similar safety. A meta-analysis of 28 studies found no significant difference in complications or 30-day mortality between robotic and laparoscopic adrenal gland removal; robotic surgery had slightly less blood loss and shorter stays but cost about US$4,100 more per hospitalization. (Esposito et al., Cancers, 2025) [4]
Key takeaways
Endocrine surgery treats diseased hormone glands, mainly the thyroid, parathyroid and adrenal glands, and sometimes the pancreas. [1]
The four main operations are thyroidectomy, parathyroidectomy, adrenalectomy and pancreatectomy. [1]
Surgeons use laparoscopic, robotic or open methods; small incisions can mean faster recovery with less pain and scarring. [1]
Some people need medicine afterward, for a short time or for life, such as thyroid hormone, calcium and vitamin D, or steroids. [1]
Most people return to work or school after one to two weeks. [1]
Call your doctor for breathing trouble, voice changes, tingling in the face, lips, hands or feet, or signs of infection. [1]
What is endocrine surgery?
Endocrine surgery is a group of operations that treat disorders of the glands in your endocrine system, mostly the thyroid, parathyroid and adrenal glands. [1]
Glands are organs that release hormones into your bloodstream. Hormones carry messages that tell tissues what to do to keep your body healthy. [1]
You may need surgery when a gland stops working correctly. It may release too much hormone, or not enough. [1]
What does the endocrine system do?
The endocrine system makes hormones your body uses for growth, breathing, metabolism and many other daily functions. [1]
Body growth and sexual development
Breathing
Movement
Pregnancy and reproduction
Sensory perception [1]
Which glands does endocrine surgery treat?
Endocrine surgery mainly treats three glands: the thyroid, the parathyroid glands and the adrenal glands. [1]
Gland | Where it sits | What it controls |
Thyroid | Butterfly-shaped gland at the front of your neck | Metabolism: how your body makes heat and uses energy and oxygen |
Four small glands behind the thyroid | Calcium and phosphorus levels, which are vital for bone development | |
One above each kidney | Cortisol (stress hormone), androgens (sex hormones) and aldosterone (blood pressure) |
What conditions are treated with endocrine surgery?
Endocrine surgery treats tumors, cancers and overactive glands in the thyroid, parathyroid and adrenal glands, plus some inherited and neuroendocrine tumors. [1]
Gland | Conditions that may need surgery |
Thyroid | Hyperthyroidism, goiter, Graves' disease, toxic (overactive) thyroid nodules, thyroid nodules, thyroid cancer, PTEN hamartoma tumor syndrome (Cowden syndrome) |
Parathyroid | Hyperparathyroidism, parathyroid adenomas, parathyroid cancer |
Adrenal | |
Other endocrine sites |
Who performs endocrine surgery?
Endocrine surgery is performed by endocrine surgeons, who are general surgeons with extra training in operating on hormone glands. [1]
An endocrinologist is a medical doctor who diagnoses hormone diseases and treats them with medicines. If you need an operation, your endocrinologist may refer you to an endocrine surgeon. [1]
Endocrine surgery is a relatively new subspecialty of general surgery, so not every hospital has an endocrine surgeon. At some hospitals, a general surgeon performs these operations alongside other surgeries. [1]
Because experience matters, it is worth choosing a surgeon who has treated your specific condition before. [1] [2]
What are the types of endocrine surgery?
The four main types of endocrine surgery are thyroidectomy, parathyroidectomy, adrenalectomy and pancreatectomy. [1]
Operation | What is removed | Medicine you may need afterward |
Thyroidectomy | The whole thyroid, or one lobe (thyroid lobectomy) | Thyroid hormone |
Parathyroidectomy | One or more of the four parathyroid glands | Calcium and vitamin D |
One or both adrenal glands | Steroids | |
Part or all of the pancreas | Depends on how much is removed |
What happens before endocrine surgery?
Before endocrine surgery, you follow your surgeon's instructions and have tests that show how the gland is working and where the problem is. [1]
Your surgeon may ask you to:
Fast (not eat or drink) for a set time before surgery.
Stop certain medicines, including vitamins and herbal supplements.
Quit smoking. [1]
Test | Why it is done |
Blood tests | Check how well the gland is working |
CT scan, ultrasound or MRI | Show the size and location of the gland or tumor |
Bronchoscopy | Checks whether a tumor affects your windpipe (trachea) |
Laryngoscopy | Checks the health of your vocal cords |
Needle biopsy | Looks for cancer cells |
Upper endoscopy or barium swallow | Examines your food pipe (esophagus) |
What happens during endocrine surgery?
During endocrine surgery, you are asleep under general anesthesia while the surgeon removes the diseased gland in a hospital or surgical center. [1]
Your surgeon chooses one of three approaches, depending on your condition. [1]
Approach | How it works | When it is used |
Laparoscopic | A few small cuts; a thin tube with a light and camera (laparoscope) guides removal | Minimally invasive; may mean faster recovery with less pain and scarring |
Robotic | Robotic and laparoscopic tools work through small cuts | Another minimally invasive option |
Open | One cut directly over the gland | May be needed for a large, cancerous tumor |
How long does endocrine surgery take?
Endocrine surgery can take from about one hour to three hours, depending on the condition and how complex the operation is. [1]
Removing part of the thyroid may take about one hour. A total thyroidectomy for thyroid cancer that also removes nearby lymph nodes may take up to three hours. Your surgeon will tell you what to expect. [1]
What happens after endocrine surgery?
After endocrine surgery, the removed tissue is often sent to a lab to check for cancer, and some people start new medicines. [1]
The lab results may show that you need more treatment. For example, people with thyroid cancer may need radioactive iodine therapy after surgery. [1]
Depending on the operation, you may need medicine for a short time or for life:
Calcium and vitamin D after a parathyroidectomy.
Steroids after an adrenalectomy.
Thyroid hormone after a thyroidectomy. [1]
What are the benefits of endocrine surgery?
Endocrine surgery can cure certain endocrine disorders, ease or stop symptoms and improve quality of life. [1]
Treating the gland problem can also lower your risk of other health problems:
Heart rhythm problems (arrhythmias), blood clots and strokes
Heart disease and heart failure
High blood pressure
Type 2 diabetes [1]
What are the risks of endocrine surgery?
Like all surgery, endocrine surgery carries a risk of complications, including bleeding, infection, nerve injury and low calcium levels. [1]
Blood pressure changes
Bruising
Damage to nearby glands, organs, nerves or blood vessels
Infection
Injury to nerves in the voice box, which can cause temporary or permanent hoarseness or a weak voice
Internal bleeding, blood loss and blood clots
Low calcium levels (hypoparathyroidism)
Breathing problems such as pneumonia or shortness of breath [1]
What is recovery like after endocrine surgery?
Recovery after endocrine surgery usually starts with at least one night in hospital and continues with one to two weeks at home. [1]
You may have a mild sore throat and some pain. Following your discharge instructions closely helps you heal and lowers your risk of complications. [1]
At-home recovery may include:
Resting and not lifting anything heavy for a set time.
Changing wound dressings regularly, if needed.
Eating soft foods, drinking cold drinks or sucking on ice chips to soothe a sore throat.
Starting hormone therapy, steroids or supplements, if needed.
Staying home from work or school for one to two weeks.
Taking over-the-counter or prescription pain relievers as directed. [1]
Your long-term outlook depends on your condition, your overall health and how well treatment works. Your surgeon or endocrinologist can explain your own outlook. [1]
When should you call a doctor after endocrine surgery?
Call your doctor after endocrine surgery if you have breathing problems, voice changes, tingling or numbness, or signs of infection. [1]
Difficulty breathing or voice changes
Numbness or tingling in your face, lips, hands or feet
Signs of infection, such as redness or yellow discharge at the incision, or a fever
Bruising, redness or swelling at the incision that lasts more than a week [1]
If breathing becomes hard, seek emergency care right away.

FAQ
What is endocrine surgery?
Endocrine surgery is an operation that removes part or all of a diseased hormone gland, most often the thyroid, parathyroid or adrenal glands. It treats conditions such as thyroid cancer, overactive glands and adrenal tumors.
What conditions need endocrine surgery?
Common reasons include thyroid cancer, thyroid nodules, goiter, Graves' disease, hyperparathyroidism and adrenal tumors such as pheochromocytoma. Multiple endocrine neoplasia syndromes and neuroendocrine tumors may also need surgery.
Is an endocrine surgeon the same as an endocrinologist?
No. An endocrinologist diagnoses hormone diseases and treats them with medicine, while an endocrine surgeon is a general surgeon with extra training in operating on hormone glands.
How long does endocrine surgery take?
Removing part of the thyroid may take about one hour. A total thyroidectomy with removal of nearby lymph nodes for cancer may take up to three hours.
What are the main risks of endocrine surgery?
Risks include bleeding, infection, blood pressure changes, low calcium, and injury to voice box nerves that can cause hoarseness or a weak voice. Some of these effects are temporary, and some can be permanent.
How long is recovery after endocrine surgery?
Most people stay in hospital for at least one night and stay home from work or school for one to two weeks. A mild sore throat and some pain are common at first.
Will I need medicine for life after endocrine surgery?
Some people do. You may need thyroid hormone after a thyroidectomy, calcium and vitamin D after a parathyroidectomy, or steroids after an adrenalectomy, either for a short time or for life.
When should I call my doctor after endocrine surgery?
Call your doctor if you have trouble breathing, voice changes, numbness or tingling in your face, lips, hands or feet, a fever, or redness or discharge at the incision. Bruising or swelling that lasts more than a week also needs a check.
Will I have a scar after thyroid or parathyroid surgery?
Most people have a small scar on the front of the neck, often placed in a natural skin crease so it fades and is hard to see. Some approaches place incisions away from the neck. Ask your surgeon what to expect.
Can my voice change after thyroid or parathyroid surgery?
Hoarseness or a weak voice can happen if the nerves near the thyroid are irritated. It is usually temporary, but tell your surgeon if it lasts, and get help right away for trouble breathing.
