Imaging intraabdominal abscesses and nonoperative drainage procedures

With state-of-the-art imaging and interventional techniques, the diagnosis and management of intraabdominal abscesses have improved. Radionuclide scanning, ultrasound, and computed tomography are very accurate for the diagnosis and staging of intraabdominal abscesses, permitting the use of percutaneous drainage methods. Percutaneous abscess drainage (PAD) has gained wide acceptance and applications now include not only curative drainages but also certain palliative ones. Although some controversy exists relative to results and palliative procedures, PAD is now accepted as an effective alternative to operative drainage.
