Gastroscopy, also known as upper endoscopy or esophagogastroduodenoscopy (EGD), is a procedure that allows your gastroenterologist to examine the lining of your upper digestive tract -- the esophagus, stomach, and first part of the small intestine (duodenum). A thin, flexible tube called an endoscope with a tiny camera on the end is gently passed through your mouth and into your digestive tract.
Dr. Jing Tong, a Johns Hopkins School of Medicine trained gastroenterologist and one of the few US specialists licensed in therapeutic endoscopy, uses state-of-the-art high-definition endoscopy equipment. This advanced imaging technology provides superior visualization of mucosal abnormalities, enabling earlier detection of conditions such as Barrett's esophagus, gastric ulcers, and early-stage cancers.
At our conveniently located Flushing, Queens office, we perform gastroscopy with sedation for your comfort. The procedure typically takes 10-15 minutes, and most patients can return home the same day. Dr. Tong's extensive experience ensures precise diagnosis and, when necessary, immediate therapeutic intervention during the same procedure.

You will be asked to fast for 6-8 hours before the procedure. Dr. Tong will review your medical history and current medications. Certain blood thinners may need to be temporarily paused.
Intravenous sedation is administered so you remain comfortable and relaxed throughout the procedure. You will not feel pain and most patients have no memory of the procedure.
The HD endoscope is gently guided through your mouth into your esophagus, stomach, and duodenum. Dr. Tong carefully examines the mucosal lining, capturing high-resolution images of any abnormalities.
If abnormal tissue is found, Dr. Tong can take tissue samples (biopsies) for laboratory analysis. As a therapeutic endoscopy specialist, he can also perform treatments such as polyp removal, bleeding control, or dilation during the same procedure.
You will rest in the recovery area for 20-30 minutes as the sedation wears off. Dr. Tong will discuss preliminary findings with you before you leave. Biopsy results are typically available within a few days.
Dr. Tong completed his gastroenterology training at the prestigious Johns Hopkins School of Medicine, one of the top medical institutions in the world.
