What is Endoscopy?
Endoscopy is a medical procedure that involves inserting a flexible tube with a camera into the digestive tract. It allows doctors to directly view the inside of organs like the esophagus, stomach, and colon. This procedure is crucial for identifying sources of bleeding and diagnosing conditions like ulcers, tumors, or inflammation.
Upper Endoscopy vs. Colonoscopy
Upper endoscopy examines the upper digestive tract, including the esophagus, stomach, and duodenum. It's essential for detecting upper GI lesions, which are often present in patients with positive fecal occult blood tests. Colonoscopy, on the other hand, focuses on the colon and rectum, identifying issues like polyps or colorectal cancer. Both procedures are complementary in evaluating GI bleeding.
When is Endoscopy Recommended?
Endoscopy is recommended when there's a positive fecal occult blood test or unexplained iron deficiency anemia. It's particularly useful when initial tests don't reveal a bleeding source. In such cases, both upper endoscopy and colonoscopy are often performed to ensure a comprehensive evaluation.
