A modified procedure for percutaneous abscess and fluid drainage using the Malecot catheter-Stamey needle technique.
Percutaneous abscess and fluid drainage (PAFD) of various intraabdominal collections with computed tomographic and ultrasonic guidance is well established. Current techniques use a catheter of pigtail design introduced either by multiple step dilatations or a separate trocar insertion, and are subject to complications which can be avoided by use of a new catheter-needle system we propose. This system uses a straight, winged, Malecot catheter which is introduced in one step with a Stamey needle. We report upon our experience with the Malecot catheter/Stamey needle system for PAFD in 13 patients with good results. This method ensures a single step introduction of a large bore catheter, accurate catheter placement, a stable catheter position with good function, and easy drainage of multiloculated or multiple abscesses.
