Experiencing discomfort in your gastrointestinal (GI) tract can be unsettling. If you’re facing persistent symptoms, understanding the potential diagnostic tools available is crucial. An upper endoscopy is a minimally invasive procedure that provides a clear view of your upper digestive system, allowing doctors to detect a range of diseases and conditions. At Akron Digestive Disease Consultants in Akron, OH, their expert team utilizes upper endoscopy to accurately diagnose and address various GI issues.
Understanding Upper Endoscopy and Its Diagnostic Capabilities
An upper endoscopy, also known as esophagogastroduodenoscopy (EGD), is a procedure that employs a thin, flexible tube equipped with a camera. This endoscope is gently inserted through your mouth and guided down into your esophagus, stomach, and duodenum (the first part of your small intestine). This allows gastroenterologists to directly visualize the lining of your upper GI tract, identify abnormalities, and diagnose a multitude of conditions.
Endoscopies are recommended for a variety of reasons, particularly when investigating the cause of symptoms such as persistent abdominal pain, nausea, vomiting, unexplained bleeding, difficulty swallowing (dysphagia), and chronic heartburn. Here are some of the key diseases and conditions that an upper endoscopy can effectively detect:
Ulcers: Peptic and Gastric
Ulcers are open sores that develop on the lining of the stomach (gastric ulcers) or the upper part of the small intestine (duodenal ulcers). They are often caused by stomach acid erosion, long-term use of nonsteroidal anti-inflammatory drugs (NSAIDs), or infection with Helicobacter pylori (H. pylori) bacteria. An endoscopy can directly visualize ulcers, determine their severity, and even take biopsies to test for H. pylori and rule out malignancy. Symptoms of ulcers can include burning stomach pain, bloating, nausea, and vomiting.

Gastroesophageal Reflux Disease (GERD) and Barrett’s Esophagus
GERD is a common condition where stomach acid frequently flows back into the esophagus, irritating its lining. This backflow, or reflux, occurs when the lower esophageal sphincter (LES) muscle weakens or doesn’t close properly. Endoscopy can help diagnose GERD, particularly when symptoms like heartburn, regurgitation, and indigestion are persistent or severe. Furthermore, endoscopy is crucial for detecting Barrett’s esophagus, a complication of chronic GERD where the esophageal lining changes and becomes more susceptible to esophageal cancer. Biopsies taken during an endoscopy can identify Barrett’s esophagus and monitor for precancerous changes.

Esophageal Strictures and Swallowing Difficulties
Difficulty swallowing, or dysphagia, can be a sign of esophageal strictures, which are narrowings of the esophagus. These strictures can be caused by GERD, scarring from inflammation, or, less commonly, tumors. An endoscopy is essential for visualizing and diagnosing esophageal strictures. It can determine the location and severity of the narrowing and help identify the underlying cause. In some cases, the endoscope can also be used to dilate or stretch the stricture during the procedure to improve swallowing.

Celiac Disease
Celiac disease is an autoimmune disorder triggered by gluten, a protein found in wheat, barley, and rye. It damages the lining of the small intestine, leading to malabsorption of nutrients. While blood tests can suggest celiac disease, an endoscopy with biopsies of the duodenum is the gold standard for diagnosis. The biopsies examined under a microscope can reveal the characteristic damage to the intestinal villi caused by celiac disease.

Pancreatitis (Chronic)
While not directly visualizing the pancreas, an upper endoscopy, particularly with endoscopic ultrasound (EUS), can be instrumental in diagnosing chronic pancreatitis and related conditions. EUS combines endoscopy with ultrasound technology, providing detailed images of the pancreas and surrounding tissues. It can detect inflammation, cysts, tumors, and blockages in the pancreatic ducts. EUS is especially valuable when standard imaging tests are inconclusive.

Gastritis and Esophagitis
Gastritis (inflammation of the stomach lining) and esophagitis (inflammation of the esophageal lining) are conditions that can cause a range of symptoms including abdominal pain, nausea, vomiting, and heartburn. Endoscopy is a definitive way to diagnose these conditions by directly visualizing the lining of the stomach and esophagus and taking biopsies if necessary to determine the cause of inflammation, such as H. pylori infection, medication use, or acid reflux.
Gastrointestinal Cancers
Endoscopy plays a crucial role in the detection and diagnosis of cancers of the esophagus, stomach, and duodenum. It allows for direct visualization of any suspicious lesions, tumors, or abnormal tissue growths. Biopsies taken during the endoscopy are essential for confirming the presence of cancer, determining the type of cancer, and staging its progression. Early detection through endoscopy significantly improves the prognosis for gastrointestinal cancers.
