Diagnosis and Treatment

Upper and Lower Endoscopy

Endoscopy is a procedure that allows a Gastroenterologist to look at the inside of the gastrointestinal tract using an endoscope. An endoscopy is performed to discover reasons for problems including swallowing difficulties, bleeding, indigestion, abdominal pain, nausea, vomiting, reflux, chest pain or diarrhea.

Capsule Endoscopy

Capsule endoscopy is used to look at the inside lining of the small intestine. Conventional upper endoscopy will only visualize the beginning of the small intestine, and colonoscopy will only visualize the end of small intestine. Capsule endoscopy is a way of bridging that gap to see the entire intestine.

pH Probe Study

A pH probe study is designed to assess acid reflux in your child. Sometimes this study can be performed "with impedance," which means that it will also detect non-acid reflux.
