What is endoscopic thyroid surgery?
Thyroid gland is accessed from distant sites and Thyroidectomy is performed using an endoscope . It is also a minimally invasive surgical procedure that avoids neck incision.
Who can have endoscopic thyroid surgery
Earlier it was restricted for benign tumors but with advances in skills and development in surgical instruments it has been extended to malignant tumors of tthyroid also. Different studies have reported variable indications for endoscopic thyroidectomy. It is usually indicated for benign nodules and malignant nodules(differentiated thyroid cancer) less than 3cms in size with no extrathyroid ,lymphnode or distant spread.
Benefits of endoscopic thyroidectomy
- Superior cosmetic result.
- Significantly reduces the incidence of hypesthesia or paresthesia and discomfort while swallowing.
- The postoperative pain is comparatively less severe
- Improved visualization
- There by reducing post operative complications
- It is less cumbersome when compared to endoscopic thyroidectomy.
Endoscopic thyroidectomy treatment process (ET)
ET can be divided into video-assisted thyroidectomy (VAT) and total endoscopic thyroidectomy (TET). VAT works with an incision length of 1.5–2.0 cm in the anterior lower neck and gasless lifting system. TET does not involve neck incision and is cosmetically superior than VAT.
According to the insertion site of the surgical instruments, ET surgery can be divided into a cervical, anterior chest wall, breast, axilla, axilla-breast approach, trans oral and so on, each of which has its own advantages.
Thyroid tumor is accessed depending on the type of above mentioned approach used and the procedure of surgical removal of the tumor is similar to described above in robotic section.
Post surgery recovery
Recovery from robotic thyroid surgery is similar to recovery from conventional surgery. Patients are usually discharged after 48 hours of observation. Patients are recalled after a week for general check up and removal of sutures if any.
