Abstract
Intraoperative pancraticosonography was employed in six patients to localize suspected endocrine tumours and to study the specific ultrasonic features. The cases included four insulinomas, one case of occult G-cell apudoma and one case of beta-cell microadenomatosis. Endocrine tumours are generally hypoechoeic and well defined with smooth borders. The study confirms that real-time operative high resolution sonography is a reliable technique to assist in the diagnosis of occult endocrine tumours and to guide the surgical approach.
