Endoscopy of the upper gastrointestinal tract (oesophagus, stomach, and duodenum) is essential for diagnosing and managing conditions like reflux, coeliac disease, and eosinophilic oesophagitis. The Specialist Network consults with paediatricians for long-term management. Further investigations and surgeries, such as fundoplication, can be considered if necessary.

In cases of rectal bleeding in children, endoscopy of the large bowel (colonoscopy / flexible sigmoidoscopy) provides valuable information. For possible inflammatory bowel disease, an ileo-colonoscopy may be required, which is performed by a paediatric gastroenterologist.
