Inadvertent percutaneous catheter gastroenterostomy during abscess drainage: significance and management.

Eleven cases of inadvertent catheter insertion into the small bowel or stomach during percutaneous abdominal abscess drainage are reviewed. Recognition of the intraluminal catheter position was made by contrast-enhanced fluoroscopy in all patients 1-6 days after catheter insertion. No evidence of leakage of intestinal contents into the peritoneal cavity was noted either clinically or radiologically. All cases occurred after drainage of a centrally located midabdominal collection, but the ultimate outcome was not compromised. In nine of 11 cases, catheter drainage alone was sufficient; two cases required additional surgical drainage. Considerations for management include a prolonged period of catheter drainage to allow evolution of a fibrous tract and gradual catheter withdrawal. These data confirm the growing experience with purposeful percutaneous gastrostomy that percutaneous catheterization of the gastrointestinal tract can occur without major sequelae.
