[Non-surgical drainage of intra-abdominal abscesses]

Intra-abdominal abscesses were treated by percutaneous needle drainage. Diagnosis was based, in 100% of the cases, on clinical findings, flat abdomen X-rays and ultrasound. 71% had previous abdominal surgery and 17% had abdominal trauma. The abscesses were located as follows: 29% in the liver, 24% in right sub-diaphragmatic area, 41% had several locations and 6% was pyogenic collection in de common biliary duct. The average duration of drainage was 9 days. Fifteen out of the 17 procedures were successful (88%). Predominant germs obtained in cultures of the drained material were E. Coli and P. Aeruginosa.

the above experience demonstrate that percutaneous drainage in intra-abdominal abscesses is a secure and effective procedure with high rate of success and low of morbidity and mortality. It must be considered as treatment of choice.
