Abstract
Narrow-band imaging uses selective haemoglobin light absorption to emphasise vascular visualisation and capillary networks. This study aimed to evaluate the application of this technique to parathyroid surgery. This preliminary evaluation was carried out on five consecutive patients with single parathyroid adenoma being considered for minimally invasive video-assisted parathyroidectomy. The adenomas were checked for narrow-band imaging vascular patterns. Minimally invasive video-assisted parathyroidectomy was then carried out in accordance with our standard protocol. In four out of the five cases, narrow-band imaging integrated the white endoscopic light and direct vision, but in one case narrow-band imaging allowed distinction between the hidden neoplastic tissue and the surrounding structures thanks to the different vascular patterns. Narrow-band imaging was helpful in properly identifying adenoma. It is suggested that this technique be considered as a means for surgeons to improve their confidence in selected surgical treatments and to improve treatment quality.
