Necrotizing fasciitis following gastrostomy tube placement, detected by point-of-care ultrasound, case report

Introduction: Necrotizing fasciitis is a recognized rare complication of gastrostomy tube replacement, but if it occurs and is not discovered early, a lethal outcome is possible.Case presentation: We present a woman in her 80s who was known to have chronic atrial fibrillation with ischemic heart disease. She was fed through percutaneous endoscopic gastrostomy after brain injury. Erythema was observed around the stoma of the gastrostomy tube, which was later removed, and erythema extended to the left anterior abdomen. The patient was diagnosed with cellulitis. Point-of-care ultrasound examination suspected necrotizing fasciitis and, confirmed later by computerized tomography of the abdomen. The case was managed surgically.Discussion: Patients with a high clinical suspicion of necrotizing fasciitis should undergo early surgical debridement with antibiotic administration. Necrotizing fasciitis starts with a clinical picture indistinguishable from other skin infections, such as cellulitis, and imaging modalities are important for confirmation and early diagnosis. We present a case of necrotizing fasciitis after gastrostomy tube replacement for which point-of-care ultrasound played a pivotal role in confirming the diagnosis early.Conclusion: Point-of-care ultrasound is a useful adjunct tool for clinical evaluation and assessment in diagnosing early critically ill patients with life-threatening necrotizing infections.
