[Initial experiences with the intraoperative sonography in visceral surgery].

Intraoperative sonography (IOUS), which had gained importance from the mid-seventies, was introduced at our clinic in November 1987. To this day, 32 patients have been examined, of which twelve had an examination of the liver, eight of the pancreas and one of the bile ducts. In ten cases surgical strategy was influenced by IOUS. After a comment on the equipment and on the conditions this has to meet, the technique and the difficulties of the IOUS examination of the liver, the pancreas and the bile ducts are discussed. Our own results are compared with those of the literature.
