Abstract: Results of minimal invasive percutaneus drainage interventions under US-control in 45 children, aged 1-4 years with intraabdominal abscesses of different genesis are presented. Intraabdominal abscesses were identified as subdiaphragmatic (16), intrafilar (22) and pelvic (19). Difference between US-characteristics of intraabdominal abscesses, preoperative planning peculiarities and interventional technologies, that depend on localization of abscesses are presented. The usage of 3D-echography results data in 13,3% of children increased the value of diagnostics: for optimization of surgical approach, kind and volume of intervention. Percutaneus drainage intervention under ultrasound control is effective and non-traumatic method of treatment. References 1. Libov S.L.
