The results of minimally invasive US-giuded punctures or drainings of intraabdominal abscesses in 45 children, aged 1-14 years, were analyzed. 16 abscesses were subdiaphragmatic, 22 were intestinal and 19 were classified as pelvic. Differences of the echographic characteristics, features of the preoperative planning and techniques of the intervention in dependence of the abscess localization, were thoroughly depicted. The authors used the virtual 3D echography in 13.3% of patients to improve the diagnostics, surgical access and volume of the intervention. Therefore, the US guided interventional surgery remains the effective and nontraumatic means for the treatment of intraabdominal abscesses.
