[Ultrasound investigation and mini-invasive ultrasound-assisted technologies in diagnosis and treatment of extra-organ separate fluid formations in abdominal cavity].

The authors discuss the use of ultrasound-assisted percutaneous puncture and drainage for diagnosis and treatment of extraorganic separate fluid formations in abdominal cavity (abscess, limited non-infected fluid formation, hematoma with clotted blood), determination of their sizes and obtaining material for laboratory study. 307 patients with various extraorganic separate fluid in formations in abdominal cavity were examined. Ultrasonic symptoms of abscess were described in 54 patients, of limited non-infected fluid formation--in 234, of hematoma with clotted blood in 19 patients. 146 patients were cured conservatively, 75 patients underwent US-assisted puncture, 76--US-assisted drainage. Mean time of drainage was 14 days (ranged from 10 to 20). There were neither complications nor lethal outcomes. Ultrasound examination and US-assisted mini-invasive surgery permit to detect precisely the nature of fluid formation, to perform timely and low-traumatic treatment.
