What are the 10 investigative procedures of gastro intestinal system
1. Endoscopy: This procedure involves the insertion of a small, flexible tube with a camera into the gastrointestinal tract to examine the lining of the esophagus, stomach, and small intestine.
2. Colonoscopy: Similar to endoscopy, but it explores the large intestine and rectum to detect abnormalities, such as polyps or tumors.
3. Barium swallow: In this test, the patient swallows a liquid containing barium, which coats the walls of the esophagus and stomach. X-ray images are then taken to visualize any abnormalities.
4. Upper gastrointestinal series: This test involves the ingestion of a liquid containing barium to coat the upper part of the digestive system. X-rays are taken to identify problems like ulcers or tumors.
5. Small bowel capsule endoscopy: This procedure requires swallowing a small capsule containing a camera that takes pictures as it passes through the small intestine, helping to diagnose issues like bleeding or inflammation.
6. Magnetic resonance imaging (MRI): This imaging technique uses magnets and radio waves to create detailed pictures of the gastrointestinal system and surrounding organs.
7. Computerized tomography (CT) scan: CT scans use multiple X-ray images to produce detailed cross-sectional images of the gastrointestinal organs, helping to detect issues like tumors or obstruction.
8. Endoscopic ultrasound (EUS): This procedure uses an endoscope with an ultrasound probe attached to examine the digestive tract walls and nearby organs for abnormalities.
9. Biopsy: During endoscopy or colonoscopy, a small tissue sample may be taken for further analysis to determine the presence of cancer, infection, or other conditions.
10. Breath tests: These tests measure the gases produced by bacteria in the gastrointestinal system, often used to diagnose conditions like lactose intolerance or bacterial overgrowth.
