Various techniques for minimally invasive thyroid surgery (MITS), including endoscopic and video-assisted procedures, have now been described. Based on our unit's experience with minimally invasive parathyroidectomy via a lateral incision, a similar technique for minimally invasive thyroid lobectomy has been developed and assessed.
The last 203 consecutive thyroid procedures using the MITS technique, performed between July 2002 and June 2006, comprised the study group. Inclusion criteria for initial surgery were: initial nodule < 3.0 cm; no preoperative evidence of malignancy; absence of clinical multinodular change. A 2.5- cm lateral incision, using a headlight illumination, provided optimal exposure.
A total of 202 patients underwent 203 MITS procedures over the 4-year period, with one patient undergoing bilateral MITS. The procedures included 155 thyroid lobectomies and 48 nodule excisions; 31 of the patients underwent a minimally invasive parathyroidectomy (MIP) during which an ipsilateral thyroid nodule was removed. The mean tumour size was 17.3 mm, but the mean size of the thyroid lobe removed was 39.5 mm. Final diagnoses included benign multinodular goitre (26%), follicular adenoma (22%) and carcinoma (20%). The complication rate was low, with one permanent recurrent laryngeal nerve (RLN) palsy (anterior division only) (0.5%), four RLN neuropraxias which recovered (2%), and one haematoma not requiring re-operation (0.5%). The rate of complications was not significantly different from 819 conventional open hemithyroidectomies performed over the same period.
MITS is a safe and feasible alternative to open thyroid surgery in appropriately selected cases. It offers a valuable option for diagnostic excision biopsy in patients with thyroid nodules demonstrating an “atypical” fine-needle biopsy whilst avoiding the need for a standard cervical “collar” incision.
