[Abdominal sonography in primary diagnosis of blunt abdominal trauma]

200 patients with blunt abdominal trauma were scanned by ultrasound primarily. 152 showed a normal sonographic examination. In 24 patients an organic injury was visualised. These 20 splenic injuries, 2 lesions of the kidney, 1 splenic and renal lesion and 1 hepatic and splenic rupture were confirmed by CT in 9 cases, by laparotomy in 9 cases, by sonographic follow-up in 2 cases. 23 patients showed an intraabdominal fluid collection, in 16 patients a decrease was seen by ultrasound. 7 patients were directly operated on because of a visible increase of intraabdominal fluid. The lesions consisted of 3 hepatic ruptures, 2 retroperitoneal bleedings. Ultrasound is a reliable tool in the diagnosis of blunt abdominal trauma on the day of admittance and in the evaluation of injuries in respect of operative or conservative management.
