Upper Endoscopy (EGD)

What is an EGD?

A GI upper endoscopy, also known as an EGD, is a procedure that allows Dr. Nowain to visualize the upper part of the gastrointestinal tract – the esophagus, stomach, and duodenum –  in order to diagnose and treat certain medical conditions.  He is highly specialized in performing an upper endoscopy, and will make sure your entire experience is as pleasant as possible.

Patients are sedated with anesthesia and a small, flexible endoscope is inserted through the mouth in order to examine the esophagus, stomach, and the first part of the small intestine.  Any abnormalities seen during the exam will be biopsied for diagnostic purposes. An upper endoscopy is very short and generally lasts between ten to fifteen minutes.

A GI upper endoscopy is a safe procedure that provides information that other tests may not be able to give. Dr. Nowaincan both diagnose and immediately treat certain GI conditions like abnormal bleeding, cancerous tissues, or polyps.


Who should perform an EGD?

An EGD should be performed by a gastroenterologist. Gastroenterologists are physicians trained to diagnose and treat conditions of the digestive tract – including the esophagus, stomach, and intestines. GI doctors also have special training in endoscopic procedures. Because GI doctors are specially trained in these techniques, the can identify the conditions better and have a lower risk of complications from the procedures.
