Also known as an esophagogastroduodenoscopy (EGD), an upper endoscopy is an examination of the upper digestive system. This upper digestive system begins at the esophagus, goes through the stomach and ends at the duodenum — the first section of the small intestine. Many different conditions and diseases can affect these structures, causing a host of symptoms.

When should I get an upper endoscopy?

Dr. Michael Flicker, Dr. Carl Atallah and Dr. Daniel Berger may recommend an upper endoscopy exam if you are experiencing:

  • Abdominal pain
  • Difficulty swallowing
  • Nausea
  • Vomiting
  • Gastrointestinal bleeding
  • Diarrhea

With the help of this exam, our gastroenterologists can investigate these symptoms, collect tissue samples for a biopsy and even treat conditions — such as widening the esophagus, cauterizing bleeding, removing a polyp or other alien objects.

What happens during the exam?

Before a patient comes in, they will be asked to not drink or eat for four to eight hours before the exam. Certain medications may also need to be halted, or the dosage changed, before the endoscopy — especially blood thinners.

During the actual exam, the patient will receive a sedative and will lie flat on a table. A flexible tube will be inserted down through the mouth and throat. This tube contains a small camera that the gastroenterologists can use to examine the structures of the upper digestive system. This can also allow our gastroenterologists to see when performing a biopsy or completing minor gastrointestinal procedures. After the exam, patients may experience some bloating, cramping, gas or a sore throat. However, please contact Advanced G.I. LLC or visit the emergency room if you experience more serious symptoms, including:

  • Fever
  • Dark or bloodied stool or vomit
  • Severe or prolonged pain in the abdomen
  • Chest pain
  • Shortness of breath
