Gastroduodenoscopy

Gastroduodenoscopy is a diagnostic medical procedure that allows a physician to examine the interior lining of the esophagus, stomach, and the upper part of the small intestine (duodenum) using a flexible tube equipped with a light and camera, known as an endoscope. This procedure is also commonly referred to as upper GI endoscopy, esophagogastroduodenoscopy (EGD), or simply upper endoscopy.

Indications

Gastroduodenoscopy is performed for a variety of reasons. Common indications include the evaluation of symptoms such as abdominal pain, nausea, vomiting, difficulty swallowing (dysphagia), and gastrointestinal bleeding. It is also used to diagnose conditions such as gastroesophageal reflux disease (GERD), peptic ulcers, gastritis, celiac disease, and Barrett's esophagus. Additionally, it can be used for the removal of foreign bodies, biopsy of suspicious areas, and treatment of certain conditions like bleeding ulcers.

Procedure

Before the procedure, patients are usually advised to fast for a specific period, typically 6-8 hours, to ensure an empty stomach. Sedation is often provided to help with relaxation and minimize discomfort during the examination.

During gastroduodenoscopy, the patient lies on their side, and the endoscope is gently inserted through the mouth, down the esophagus, and into the stomach and duodenum. Air may be introduced through the endoscope to inflate the stomach and duodenum, improving visibility. The camera attached to the endoscope transmits images to a monitor, allowing the physician to examine the lining of these organs in detail. If necessary, instruments can be passed through the endoscope to perform biopsies or treat certain conditions.

Risks and Complications

While gastroduodenoscopy is generally safe, it carries a small risk of complications. These may include reactions to sedation, bleeding from biopsy sites, perforation (tear) of the stomach or esophagus lining, and infection. The risk of serious complications is low.

Aftercare

After the procedure, patients are monitored until the effects of sedation wear off. They may experience mild throat discomfort, bloating, or nausea, which typically resolve quickly. Due to the sedation, patients are advised not to drive or operate heavy machinery for 24 hours following the procedure.

Conclusion

Gastroduodenoscopy is a valuable tool in the diagnosis and treatment of various upper gastrointestinal disorders. It provides detailed visual information that cannot be obtained through other diagnostic tests, making it an essential procedure in modern gastroenterology.
