A Clinical Analysis of Endoscopic Thyroidectomy via Bilateral Axillo-breast Approach: A 5-year Experience / 대한내분비외과학회지

ABSTRACT

PURPOSE: We investigated the efficacy and safety of endoscopic thyroidectomy using bilateral axillo-breast approach (BABA) by analyzing short term surgical outcomes. METHODS: We retrospectively evaluated 355 patients who underwent BABA endoscopic thyroidectomy between August 2006 and December 2011 at Chonnam National University Hospital and Hwasun Chonnam National University Hospital. The age, sex, clinical and pathologic characteristics of tumors, extent of operation, conversion rate to open thyroidectomy, operation time, hospital stay, thyroglobulin levels after thyroidectomy, recurrence, and complications were analyzed retrospectively. RESULTS: The mean age of the patients was 35 years. The 355 patients comprised 345 females (97.2%) and 10 males (2.8%). The benign tumor was 37 cases (10.4%) and the malignant tumor was 318 cases (89.6%). 28 patients (75.7%) of the benign tumor underwent lobectomy. In malignant tumor, 159 patients (50.0%) underwent lobectomy and 152 patients (47.8%) underwent total thyroidectomy. Mean operation time was 121.1+/-49.9 minutes, and mean hospital days were 3.4+/-1.1 days. 21 (6.0%) transient hypocalcemia and 7 (2.0%) permanent hypocalcemia were occurred. The transient voice change occurred in 5 patients (1.4%), but nobody suffered from the permanent recurrent laryngeal nerve injury. 4 patients of recurrent (1.3%) papillary thyroid carcinoma were treated by surgery. CONCLUSION: Compare to open thyroidectomy with long term follow up studies, BABA endoscopic thyroidectomy is a useful treatment option for both benign and malignant thyroid tumor.
