Endoscopy is a commonly used procedure in gastroenterology. It allows doctors to view the inside of the gastrointestinal tract using a flexible tube with a camera. This procedure helps effectively examine and diagnose various gastrointestinal conditions.
What Is an Endoscopy?
An endoscopy is a non-surgical diagnostic procedure that enables doctors to visually inspect parts of the digestive system. A thin, flexible tube called an endoscope is inserted into the body through the mouth or rectum. The tube contains a small camera and light that transmit images to a monitor, allowing the doctor to observe and assess the health of tissues and organs.
Different types of endoscopy focus on various parts of the gastrointestinal system. For assessing the upper gastrointestinal tract, an esophagogastroduodenoscopy (EGD) is commonly performed, while a colonoscopy examines the lower gastrointestinal tract and rectum. A patient undergoing the procedure may receive sedation or anesthesia for comfort, depending on the type of endoscopy and individual needs.
Why Would I Need an Endoscopy?
Doctors may recommend an endoscopy when symptoms suggest a problem within the gastrointestinal tract. Digestive discomfort, including symptoms like abdominal pain, nausea, vomiting, or heartburn, can prompt an evaluation using this procedure. The presence of unexplained changes in bowel habits, such as constipation, diarrhea, or irregular stools, can also lead to an endoscopy recommendation.
The procedure may assist in investigating the causes of gastrointestinal bleeding or anemia. Blood in stools, black tarry stools, or iron deficiency can indicate bleeding in the digestive tract, and endoscopy helps locate the source. Individuals with symptoms such as difficulty swallowing or persistent sore throat might undergo an endoscopy to evaluate potential structural or functional abnormalities. Endoscopy may be used for routine screening of individuals at risk for certain conditions, such as colorectal cancer or Barrett’s esophagus. It is also used to monitor existing conditions, including inflammatory bowel disease or ulcers, ensuring that patients receive timely care.
How Does an Endoscopy Help With Diagnosis?
Endoscopy helps doctors closely examine the gastrointestinal tract, allowing them to observe abnormalities that might not appear through other diagnostic tests. The visual inspection provides insights into potential issues like inflammation, ulcers, strictures, or tumors. With real-time imaging, doctors can obtain accurate information to support a diagnosis.
This procedure also allows for tissue sampling through biopsy. By collecting small samples of tissue, doctors can analyze the material for signs of infection, cancer, or other abnormalities. The biopsy further aids in confirming or ruling out specific conditions.
Endoscopy simplifies the process of identifying structural issues that might be causing symptoms. Blockages, swelling, or irregularities in the shape of the digestive tract can be detected and assessed. This not only facilitates diagnosis but also helps doctors create targeted treatment plans for individual patients.
Talk To Your Doctor
Speak with your doctor if you are experiencing symptoms that may require further assessment. They can explain why an endoscopy may benefit your situation and discuss what you can expect during the procedure. Asking questions and sharing any concerns can help you prepare and feel confident about next steps.
