[Intraoperative sonography].

Intraoperative sonography was introduced at our institution in November 1987. We have since examined 55 patients, of which 27 suffered from liver disease, 16 from pancreatic problems and 11 from hyperparathyroidism. A short description of the technique applied is given for each organ. The intraoperative sonography of the liver showed additional information in one third of the cases. The sensitivity of intraoperative sonography in hyperparathyroidism was 78%, the specificity 72%.
