PY - 2010 T2 - Pediatric Practice: Gastroenterology AB - Gastritis is an inflammatory process associated with gastric mucosal injury. It is usually classified by histologic features (atrophic or non-atrophic, chemical, granulomatous, eosinophilic, lymphocytic, etc.), time course (acute versus chronic), etiology (Helicobacter pylori, bile, non-steroidal anti-inflammatory drugs (NSAIDs), Crohn’s disease, etc.), and proposed pathophysiology. Peptic ulcers are deep mucosal ulcerations that penetrate into the muscularis mucosa of the stomach or duodenum. Peptic erosions are superficial mucosal lesions; they do not involve the muscularis mucosa. Peptic ulcers and erosions are relatively uncommon in children, found in less than 25% of children undergoing upper gastrointestinal endoscopy for abdominal pain.1H. pylori is by far the most common etiology for gastritis and peptic ulcer disease (PUD) in the pediatric age group.
