ABSTRACT
Objective:To investigate the feasibility and safety of a new method of natural orifice transluminal endoscopic surgery(NOTES) -totally transtracheal endoscopic thyroidectomy(TTET) .Methods:Three miniature swines and 6 beagle dogs were underwent TTET.Under general anesthesia,special designed endotracheal tube with 2-channel was used and endoscope and instruments were inserted through the respective channel.Incision of tracheal anterior wall was accomplished and partial or subtotal thyroidectomy was performed.Finally,the defects in the trachea were sutured with ENDO STITCH instrument.Results:Partial thyroidectomy was successfully accomplished on 3 pigs and subtotal thyroidectomy was done on 6 dogs.No serious complications such as anoxia,asphyxia,airway obstruction and death occurred during the operation.Animals were sacrificed 2h after the procedure and incision of trachea was found to be closely sutured.There were no subcutaneous emphysema and haematoma formation.Conclusion:Preliminary experimental results showed the feasibility and safety of TTET.Transtracheal access maintains the integrity of cervical tissues and achieves an optimal cosmetic outcome.TTET may open up a new field of NOTES on thyroid surgery.
