Etiology and Treatment of Childhood Peptic Ulcer Disease in Taiwan: A Single Center 9-Year Experience

Background/Purpose: Peptic ulcer disease (PUD) in children is relatively rare as compared with adults. This study aimed to assess the etiology, clinical and histological characteristics, and treatment of PUD in children. Methods: All children aged < 18 years with an endoscopic diagnosis of PUD were enrolled in a tertiary referral center. The demographic data, clinical, endoscopic, and histological findings were compared between patients with different causes of PUD. Results: From 1234 endoscopic examinations, 67 (5.4%) children (median age, 11.4 years) with gastric ulcer (GU; n = 27) or duodenal ulcer (DU; n = 40) were included. Thirty-two (47.7%) of them had Helicobacter pylori infection and 11 (16.5%) had previous use of non-steroidal anti-inflammatory drugs (NSAIDs). Non-H. pylori, non-NSAID PUD was found in 24 (35.8%) patients. Children with H. pylori-related PUD had a significantly higher mean age, antral chronic inflammatory score, rate of familial PUD, and presence of DU and nodular gastritis than those with NSAID-related and non-H. pylori, non-NSAID PUD (p < 0.01). In contrast, children with NSAID-related PUD had a higher rate of upper gastrointestinal bleeding, associated with acute febrile disease, than those with H. pylori-related and non-H. pylori, non-NSAID PUD (p < 0.05). All but two patients with non-H. pylori, non-NSAID PUD were disease free after H. pylori eradication and proton pump inhibitor treatment for 1-2 months. Conclusion: In children, H. pylori-related PUD is associated with familial peptic ulcer and the presence of DU. However, short-term NSAID use is correlated highly with GU. The outcome of childhood PUD is good.
