THE RESULTS OF TREATMENT BY THE TRANSORAL ENDOSCOPIC THYROIDECTOMY BY VESTIBULAR APPROACH (TOETVA) FOR BILATERAL THYROID CANCER
Main Article Content
Abstract
Objectives: To evaluate the results of treatment by the transoral endoscopic thyroidectomy by vestibular approach (TOETVA) for bilateral thyroid cancer. Methods: A prospective study on 24 patients with bilateral thyroid cancer at Hanoi Medical University Hospital from January 2019 to December 2021. Results: 100% patients underwent transoral endoscopic thyroidectomy by vestibular approach (TOETVA) (total thyroidectomy and central lymph node dissection). The average surgery time was 104,1±33,7 minutes while the mean blood loss was 8,0±4,8ml. Transitent hypoparathyroidism: 2 cases (8,3%); transitent vocal cord palsy: 1 cases (4,1%). There were no cases of permanent hypoparathyroidism and permanent vocal cord palsy. Infection complications and numb chin did not occur in our patients. Most of patients were satisfied, 79,2% cases were extremely satisfied with the outcomes of operations. Histopathology after surgery was 100% papillary thyroid cancer. Metastasis of the central lymph nodes was detected in 14 cases (58,3%). The number of harvested and metastatic lymph node is 7,5±4,7 nodes and 1,67±1,7 nodes, respectively. After 1 month of surgery, high levels of Tg or anti-Tg after surgery were found in 2 cases (8,3%), while there was no remaining lesion detected by ultrasound after 1 month of surgery. Conclusion: TOETVA achieves safety, efficacy and initial oncological assurance in the treatment of bilateral thyroid cancer.
