Fifteen patients with Crohn disease underwent percutaneous catheter drainage of related abdominal abscesses. The abscesses were located in the right lower quadrant (five patients); in the quadratus lumborum and/or iliopsoas muscles (four patients); in the left paracolic gutter (two patients); and in the right gluteal muscles, the liver, the left subphrenic space, and the pelvis (one patient each). All abscesses were evacuated successfully (n = 15 of 15), and no patient required surgery for abscess drainage. Existing fistulas closed in four of seven patients; the other three patients underwent surgery for excision of diseased bowel and enteric fistulas. No patient developed an enterocutaneous fistula as a result of catheter drainage. Percutaneous abscess drainage is effective for abscesses related to Crohn disease and should be regarded as the procedure of choice. An operation for the abscess can be avoided, and early results suggest that bowel surgery may be obviated in selected patients.
