Esophagogastroduodenoscopy (EGD) involves inserting a camera into a long, flexible tube to examine the upper digestive tract, including the esophagus, stomach, and the beginning of the small intestine (called the duodenum), and inserting a colonoscope through the rectum to see the colon and through the distal tip of the small intestine. through the terminal ileum; however, these two types of endoscopy (upper and lower) may not see much of the middle of the small intestine. Because the small intestine is only about 6 feet long, many small bone diseases are difficult to treat with bowel imaging, computed tomography, and so on. and approximately 5% of gastrointestinal bleeding fails to find blood vessels. Capsular endoscopy may be attempted at this stage.
Capsular endoscopy allows you to examine parts of the digestive tract that other types of endoscopes are missing. It is useful when small bowel disease is suspected, and is sometimes used to find the source of gastrointestinal bleeding or the cause of unexplained abdominal pain, such as Crohn's disease. Unlike EGD or colonoscopy, however, there is no cure for the pathology that can be found. Reasons to use capsular endoscopy include unexplained bleeding, iron deficiency or abdominal pain, looking for polyps, stomach ulcers, and small bowel tumors, and a diagnosis of inflammatory bowel disease. During the test, the miniature camcorder was measured in different frequency bands. The collected images are wirelessly transmitted to the external receiver by the patient. The collected images are then transferred to a computer for display, analysis and classification. The radiofrequency signal emitted by the capsule can be detected in real time inside the body and in the digestive tract. It is unclear whether capsule endoscopy can replace gastroscopy in patients with liver cirrhosis.
Since 2014, research has focused on additional observation mechanisms and position and movement control systems to enable new applications of technology, such as drug delivery. Wireless energy transfer has also been studied as a way of continuously transferring energy to the capsule.
