What is this test? This combined procedure involves both an upper and a lower gastrointestinal (GI) endoscopic examination in a single session. First, a gastroscope—a flexible tube with a camera—is used to examine the esophagus, stomach, and duodenum (upper GI tract). Then, a colonoscope is inserted via the rectum to inspect the entire colon and distal ileum (lower GI tract). This comprehensive approach allows your physician to evaluate the full length of your digestive system for various conditions. What is it used for? * Thorough evaluation of symptoms that may affect both the upper and lower GI tract, such as unexplained abdominal pain, bleeding, or chronic digestive issues * Screening for gastrointestinal cancers and precancerous conditions throughout the digestive tract * Diagnosing inflammation, ulcers, polyps, tumors, infections, or sources of bleeding anywhere from the esophagus to the colon * Allowing biopsy or therapeutic interventions in both upper and lower GI tract during one session Who should get this test? * Patients presenting with a combination of upper GI symptoms (like heartburn, nausea, or stomach pain) and lower GI symptoms (such as rectal bleeding, diarrhea, or bowel habit changes) * Individuals requiring comprehensive GI screening due to family history or complex digestive conditions * Patients undergoing evaluation for anemia, unexplained weight loss, or chronic abdominal discomfort needing a full GI workup Preparation Required: * Fasting for 6-8 hours before the procedure to ensure an empty stomach for gastroscopy * Complete bowel preparation (cleansing) prior to the test, following your doctor’s instructions, to clear the colon for optimal visualization during colonoscopy * Arrange for sedation and transportation home, as the combined procedure requires moderate sedation or anesthesia * Discuss all medications, allergies, and medical history with your healthcare team beforehand How is the procedure performed? The combined test is typically performed under sedation in a specialized endoscopy suite. First, the gastroscope is gently passed through the mouth to examine the upper GI tract, a process that takes about 15-30 minutes. After completing the upper endoscopy, the patient is repositioned, and the colonoscope is inserted through the rectum to examine the colon, which can take 30-60 minutes depending on findings. During the entire session (lasting approximately 60-90 minutes), your physician can perform biopsies, remove polyps, or treat identified problems. This combined approach minimizes overall discomfort, avoids multiple appointments, and allows prompt, coordinated care. Risks & Safety: This procedure combines the risks associated with both gastroscopy and colonoscopy. Common side effects include mild throat soreness, bloating, or cramping. Sedation-related risks such as drowsiness or nausea can occur. Rare but serious complications include bleeding, infection, or perforation of the GI tract. Your care team closely monitors you throughout the procedure to ensure safety and comfort. Results: You will receive a comprehensive report detailing findings from both the upper and lower GI tracts. Biopsy results usually take several days and guide further diagnosis or treatment. Based on the combined findings, your physician will recommend appropriate follow-up or therapy. Short Statement: A combined, minimally invasive endoscopic examination of both the upper and lower gastrointestinal tract, providing a complete and efficient evaluation of digestive health.
