Background. Personal experience in the treatment of abscesses and abdominal fluid collections using the percutaneous drainage under ultrasound guide (PDE) is reported. This technique is progressively substituting the conventional surgical approach.
Methods. From April 1987 to March 1997, forty patients (24 men and 16 womens aged 13-84 years) underwent 47 percutaneous drainages under ultrasound guide for the treatment of 36 abscesses and 11 abdominal fluid collections. The used technique was first a preliminary needle aspiration through Chiba 22 G and then the placement of a drainage cathether using always the Seldinger technique.
Results. The results of 47 PDE (47% of which were due to post-operative abscesses) are analyzed, describing the operative technique which was successfull in 98% of cases with a morbidity rate of 4.1%. The overall mortality was 14.5% but mortality related to this method was 0%. Relapse was observed in 2.1%.
Conclusions. The effectiveness of PDE is emphasized compared with the conventional surgical approach for its minor invasivity, time of hospitalization and costs. In selected cases, as pancreatic abscesses for example, the opportunity to decide for a surgical drainage is to be considered. It is also stressed that the percutaneous techniques are to be used by the surgical team in order to improve the prognosis of critical patients.
