Upper gastrointestinal endoscopy in children with recurrent abdominal pain

Area of Science:

• Pediatric Gastroenterology
• Internal Medicine
• Microbiology

Background:

• Recurrent abdominal pain (RAP) is a common pediatric complaint with diverse etiologies.
• Previous studies suggested functional causes were more prevalent, but organic findings warrant further investigation.

Purpose of the Study:

• To investigate the prevalence of organic causes of recurrent abdominal pain (RAP) in pediatric patients.
• To identify clinical features associated with specific organic pathologies.
• To evaluate treatment responses for identified organic conditions.

Main Methods:

• A 3-year prospective study (1992-1995) involving 62 pediatric patients with RAP.
• Upper gastrointestinal endoscopy was performed to assess the upper GI tract.
• Histopathological examination and symptom correlation were utilized.

Main Results:

• Endoscopy revealed organic findings in 51.6% of patients: gastroduodenitis (27.4%), H. pylori gastritis (17.7%), and esophagitis (6.5%). No ulcers were found.
• H. pylori gastritis was associated with longer illness duration (>1 year) and vomiting.
• Triple drug therapy for H. pylori gastritis and H2 blockers for gastroduodenitis showed positive responses.

Conclusions:

• This study provides evidence for a higher prevalence of organic causes in pediatric RAP than previously reported.
• H. pylori gastritis and gastroduodenitis are significant contributors to RAP and are treatable.
• Endoscopic evaluation is crucial for diagnosing organic pathologies in children with persistent abdominal pain.
