Experience with preoperative detection of parathyroid enlargements by endosonography during transesophageal exploration is reported. Seven patients with primary hyperparathyroidism in which no preoperative localization was achieved either by the means of transcutaneous ultrasonography, or by CT, NMR, Thallium-Technectium and MIBI scan, were selected for such an exploration; among them 3 patients had previously undergone surgical exploration. A parathyroid enlargement was localized by the method in 5 of the 7 patients (3 on the back of the thyroid lobes in paraesophageal site, 1 between internal jugular vein and carotid artery and 1 in retroesophageal position); no lesion was visualized in two cases: in one, because it was located in the anterior mediastinum out of the field of US exploration; in the other case the pathologic parathyroid is still unidentified. Endosonography represents a complementary localizing procedure that should be taken into consideration when the common procedures are unsuccessful and above all in persistent a recurrent hyperparathyroidism.
