Stenotrophomonas (Xanthomonas) maltophilia infection in necrotizing pancreatitis.

Conclusion: Although the therapy of infected pancreatic collections or organized pancreatic necrosis remains surgical, we have demonstrated that infected organized pancreatic necrosis can be treated endoscopically.

Background: Stenotrophomonas (Xanthomonas) maltophilia has been increasingly recognized as a nosocomial pathogen associated with meningitis, pneumonia, conjunctivitis, soft tissue infections, endocarditis, and urinary tract infections. This organism is consistently resistant to imipenem, a drug commonly employed in patients with necrotizing pancreatitis to prevent local and systemic infections.

Methods and results: We report the first case of infected pancreatic necrosis by S. (X.) maltophilia. Our patient was treated successfully with endoscopic drainage of the pancreatic fluid collection and appropriate antibiogram-based antibiotic therapy. Endoscopic drainage has emerged as one of the treatment modalities for pancreatic fluid collections.
