Upper and lower gastrointestinal endoscopy in children and adolescents with Crohn''s disease: A prospective study

Fifty-six children and adolescents with Crohn's disease were prospectively investigated with gastroscopy and colonoscopy irrespective of localizing symptoms or signs. Routine biopsies were taken from endoscopically normal and abnormal areas. A high incidence (71%) of upper gastrointestinal (GI) involvement was found. In 41%, these findings were instrumental in making the diagnosis. The ileum was viewed in 49 of the 56 cases. Overall, the upper GI tract was involved in 71%, the terminal ileum in 53%, and the colon in 86% (oesophagus 16%, body of stomach 46%, antrum 36%, duodenum 21%, terminal ileum 53%, caecum 69%, transverse colon 71%, sigmoid 60% and rectum 41%). Upper and lower gastrointestinal endoscopy with systematic biopsies should be performed early in the diagnostic assessment of children and adolescents with suspected inflammatory bowel disease to enable accurate diagnosis and assessment of extent of disease.
