While the surgical approaches vary, the goal remains the removal of as much of the thymus as possible for best possible outcome. Some surgeons advocate the removal of the fatty tissue adjoining the thymus, while others feel the removal of the thymus alone is sufficient. The extended form of trans-sternal thymectomy, with the removal of the adjoining fatty tissue, is the most frequently used approach, while the proponents of the transcervical and VATS minimally invasive approaches believe theirs are as effective.
Depending on the type of surgery and on the condition of the patient, a ventilator may be required after surgery. Once the breathing tube has been removed, the patient will be asked to breathe deeply and cough repeatedly to clear the lungs of mucus. The patient may have one or two chest tubes small tubes in the chest attached to drainage bottles , which will be removed shortly after surgery.
Pain levels are mild after transcervical or VATS thymectomies. There can be more pain with the trans-sternal approach, but it is temporary and can be controlled through use of pain medications. Pain usually resolves in three to five days. International consensus guidance for management of myasthenia gravis. Pract Neurol. Myasthenia gravis is a long-term autoimmune condition in which muscles become tired and weak.
It affects muscles that are controlled voluntarily — commonly those controlling the eyes and eyelids, facial expression, chewing, swallowing and speaking. The muscle weakness is usually worse after physical activity or at the end of the day, and gets better with rest. Medical treatments for myasthenia gravis include pyridostigmine, an acetylcholinesterase inhibitor. This prevents the breakdown of acetylcholine, an important chemical that helps the muscles contract tighten.
This works best in mild myasthenia gravis. Steroid tablets, such as prednisolone, or other immunosupressants, are used for more severe cases. The dose can be increased gradually over time and is usually kept at a high dose for several months until remission is achieved. Thymectomy is surgery to remove the thymus — a small gland in the upper chest, just behind the breastbone.
This gland is part of the immune system, and is often abnormal in people with myasthenia gravis — although the exact role it plays is not clear. A non-cancerous tumour called a thymoma is found in about 1 in 10 people. Thymectomy is always recommended if a thymoma is found.
This blinded study of trans-sternal thymectomy in the treatment of myasthenia gravis, demonstrated reduced prednisone requirements and symptoms following thymectomy. Thymectomy reduced average alternate day steroid requirements from 60 mg to 44 mg, which is greater than expected from clinical practice. The moderate benefit of thymectomy justifies consideration of early thymectomy in appropriate patients, though which subgroup is most likely to benefit is unclear.
Important questions remain, including whether video assisted endoscopic thymectomy is as effective, and the role of thymectomy in the era of immunotherapy.

How Long Will It Take? About 1 to 3 hours Will It Hurt? Pain and swelling are common in the first 1 to 2 weeks. Medicine and home care can help. Average Hospital Stay The usual length of stay is 1 to 3 days. You may need to stay longer if you have problems. Post-procedure Care At the Hospital The staff may give you pain medicines. During your stay, the hospital staff will take steps to lower your risk of infection, such as: Washing their hands Wearing gloves or masks Keeping your incisions covered There are also steps you can take to lower your risk of infection, such as: Washing your hands often and reminding visitors and staff to do the same Reminding staff to wear gloves or masks Not letting others touch your incisions At Home The recovery time depends on the type of surgery.
Call Your Doctor Call your doctor if you are not getting better or you have: Signs of infection, such as fever and chills Redness, swelling, excessive bleeding, or any discharge from the incision Pain that you cannot control with medicine Lasting nausea or vomiting If you think you have an emergency, call for medical help right away.

Surgeons can choose from one of three techniques to perform a thymectomy: transsternal, transcervical, or videoscopic. Patients should be well-informed by their doctors about the advantages and disadvantages of the particular procedure they will undergo. Each technique applies different methods for thymus removal, and it is currently not established which one is best.
Some specialists argue it is best to remove the surrounding fat tissue along with the thymus, since this tissue may contain cells from the thymus; others believe it is not necessary. Before a thymectomy, patients are usually given intravenous immunoglobulin IVIG , plasmapheresis , or immunosuppressive therapy to reduce the risk of respiratory problems after the operation. After the operation, a patient may wake up with a breathing tube. Recovery is not painful, and patients are usually discharged within a few days after surgery.
