Endoscopes are small, flexible, lighted tubes with built-in cameras. Our gastroenterologists use endoscopes in procedures called endoscopies to see inside the body without having to perform surgery.

Endoscopies can be used to diagnose and treat gastrointestinal problems in a single visit. Our pediatric gastroenterologists use special endoscopes for children.
