gastroscopies

A gastroscopy, also known as an upper endoscopy or esophagogastroduodenoscopy (EGD), is a medical procedure used to examine the upper part of the digestive tract. This includes the esophagus, stomach, and the beginning of the small intestine (duodenum). The procedure involves inserting a thin, flexible tube called an endoscope into the mouth. The endoscope has a light and a small camera at its tip, which transmits images to a monitor, allowing the doctor to visualize the internal lining of these organs.

Gastroscopies are performed for several reasons. They are commonly used to diagnose the cause of symptoms such as persistent heartburn, abdominal pain, difficulty swallowing, nausea, vomiting, or unexplained weight loss. The procedure can also detect and help diagnose conditions like ulcers, inflammation (gastritis or esophagitis), bleeding, and cancerous or precancerous changes. During the gastroscopy, the doctor can also take small tissue samples, known as biopsies, for further examination under a microscope, which can aid in diagnosis and guide treatment.

Before the procedure, patients are typically instructed to fast for several hours to ensure the stomach is empty. Sedation is usually administered to help the patient relax and minimize discomfort. The procedure itself usually takes about 15 to 30 minutes. After the gastroscopy, patients may experience a sore throat or bloating. They will be monitored until the effects of the sedation wear off. The results of the procedure, including any biopsy findings, are usually discussed with the patient by their doctor.
