[Intraoperative abdominal echography].

Results of the use of abdominal intraoperative echography are reported for the first time in this country. The diagnostic precision, the scanning technique and the problems encountered in examining 56 patients are discussed. The high value of the method in small hepatic tumors, hepatic cysts and abscesses, common bile duct calculosis and pancreas cancer is pointed out. In operative interventions on gastrointestinal neoplasms intraoperative echography may be used for continuing surgical palpation into the butt. To master the method and introduce it as a routine method in clinical practice it is necessary, to use modern equipment, to be skilled in scanning technique and to have thorough knowledge on the characteristics of the intraoperative images of the different pathologic processes.
