[Intraoperative ultrasonography in the surgery of recurrence of well differentiated thyroid cancer]. / L'ecografia intraoperatoria nella chirurgia delle recidive del cancro differenziato della tiroide.

Surgical resection is the only curative treatment option for local recurrence of well differentiated thyroid cancer. In our experience, we found that intraoperative ultrasonography can be of significant help in facilitating the localisation and complete resection of lesions. From 2005 to 2006, 12 patients with well differentiated thyroid tumour recurrences underwent intraoperative ultrasonography. Recurrences were easily identified and resected in all patients. Postoperative thyreoglobulin was not detected. Intraoperative ulrasonography can be of significant help in the identification of well differeniated thyroid tumour recurrences, particularly when the cancer is smaller than 10 mm in diameter, and can facilitate a more radical excision of the tumour.
