What is Upper Endoscopy?

Upper Endoscopy (also known as EGD, or esophagogastroduodenoscopy) is a procedure that enables your surgeon to examine the inside of the esophagus (tube that connects the mouth to the stomach) stomach and duodenum.

A small bendable camera (endoscope) is placed through your mouth and into the stomach, for this procedure you need an advanced gastrointestinal surgeon like Dr. Arevalo to do it effectively without any discomfort to the patient.


Why Is An Upper Endoscopy Performed?

Upper Endoscopy
Upper endoscopy is performed to evaluate persistent symptoms like upper abdominal pain, fullness, bloating, early satiety, nausea, vomiting, difficulty swallowing, heartburn or Hiatal hernias.

It is more accurate than X-rays for detecting inflammation, tissue damage, ulcers or tumors of the esophagus, stomach and duodenum. Upper endoscopy can detect bacterial infection, early cancer, and can distinguish between cancerous and noncancerous conditions by performing biopsies of suspicious areas. Biopsies are taken by using a specialized instrument to sample tissue. These samples are then sent to the laboratory to be analyzed under the microscope.

A variety of instruments can be passed through the endoscope that allows advance surgeons, like Dr. Arevalo, to treat many abnormalities with little or no discomfort and with no scars.

How Should I Prepare For An Upper Endoscopy?

The stomach should be completely empty for 8 hours. Dr. Arevalo will review your list of medications list and advise you on which medications need to be stopped or continued.

Endoscopy is done while the patient is lightly sedated, for this reason, you will need to have someone drive you home afterwards.

The upper endoscopy usually takes about 10 to 15 minutes, the majority of patients fall asleep during the endoscopy. You will be continuously monitored by Dr. Arevalo through the procedure and afterwards.

What Happens After Upper Endoscopy?

You will be monitored in the recovery area for 1 to 2 hours until the effects of the sedatives have worn off. Your throat may be a little sore for a day or two. You may feel bloated after the procedure because of the air that is introduced into your stomach to check the inside.

Dr. Arevalo will inform you on the endoscopy findings after the procedure, biopsy samples can take several days for the final results.

Dr. Arevalo is an advance gastrointestinal surgeon. He is board certified by the American college of surgeons and fellowship certified by the Society of american gastrointestinal and endoscopic surgeons.
