The effect of drainage tube size on adequacy of percutaneous abscess drainage.
Fifty-one patients with documented abdominal abscess cavities were treated by percutaneous abscess and fluid drainage (PAFD). Drainage catheters made of various materials in sizes ranging from 5 through 18 French (Fr) were retrospectively studied and prospectively assigned to patients. No significant difference in the success or failure of PAFD as a function of these factors was found once an 8.3 Fr catheter with 0.045-inch diameter side-holes was reached; catheters larger than this were not associated with improved patient outcome. Failues of PAFD occurred primarily with the presence of phlegmonous collections and cavities with fistulous connection to bowel.
