[Intraabdominal abscesses. Intervention versus surgical treatment].

As the diagnosis of intraabdominal abscesses has been continuously facilitated by the use of ultrasound and CT-scan, interventional management by percutaneous drainage provides an excellent alternative treatment concept to conventional open surgery. With the use of special flow-suction-catheters which are placed into the abdomen under sonographic or computertomographic guidance, the success rates in the literature are ranging between 33% and 100%, depending on the initial situation, etiology and morphology of the findings. Studies performed with comparable patient collectives showed that interventional treatment methods had equal results to conventional surgery. Under favorable conditions such as in lesions situated in the periphery of the abdomen, with uncomplicated access ways through the abdominal wall and with an etiology of postoperative complications without a primary intraabdominal disease, with homogenous fluid collections in undivided or communicating spaces, the success rates can be raised to above 80%. A close cooperation between radiologists and surgeons in indication, conduct and course of treatment is indispensible for a successful application of these well tolerable interventional treatment concepts.
