Management of loculated abscesses that are difficult to drain: a new approach.
Fourteen critically ill patients underwent percutaneous drainage of abdominal abscesses. All 14 had one or more relative contraindications to external drainage procedure: (a) multiloculated abscesses; (b) multiple abscesses; (c) abscesses that form fistulae to surrounding organs; (d) abscesses containing viscous fluid, debris, or necrotic material. A total of 32 cavities was drained, usually using a multiple trocar/catheter system. Biplane computed tomography demonstrated a safe drainage route in all patients. In those patients in whom the contents of the abscess were too viscous to permit drainage, the contents were liquefied with acetylcysteine. Nine of the 14 patients (64%) recovered completely following the drainage procedure.
