Diagnostic utility of upper and lower gastrointestinal endoscopy for the diagnosis of acute graft‐versus‐host disease in children following stem cell transplantation: A 12‐year experience

Pediatric Transplantation, 2021
Endoscopically obtained mucosal biopsies are the gold standard for diagnosing acute graft‐versus‐host disease of the gastrointestinal tract (GI‐GVHD). There is no consensus on the ideal endoscopic approach in children.
