Gastrointestinal Bleeding in the Neonate: Updates on Diagnostics, Therapeutics, and Management

Gastrointestinal bleeding (GIB) is a relatively uncommon presentation in the NICU. GIB in neonates includes a broad spectrum of disease morbidity, from minor reflux symptoms and growth failure to severe, clinically significant anemia requiring critical care resuscitation. Over the last several years, multiple diagnostic tools including fecal calprotectin and bedside ultrasonography have emerged and demonstrated utility in the early recognition of sources for GIB in neonates. Further evidence has continued to show that traditional medical therapy with intravenous proton pump inhibitors is well-tolerated, and that upper endoscopy has limited diagnostic and therapeutic value. Finally, additional research and quality improvement investigations are warranted to determine how best to prevent, recognize, and manage GIB in critical neonates.
