Abstract—Endoscopy means looking inside and typically refers to looking inside the body for medical reasons using an endoscope. An endoscope is an instrument used to examine the interior of a hollow organ or cavity of the body. The main risks are perforation, or a tear, of the stomach or oesophagus lining and bleeding. Other minor risks include drug reactions and complications related to other diseases. To compensate on these draw backs of normal the wireless capsule endoscopy has been discovered.. Wireless capsule endoscopy is a painless medical procedure which has revolutionized endoscopies it has enabled for the first time a painless inspection of the small intestine. The procedure is based on a vitamin size pill which captures images of the digestive tract while it is transported passively by peristalsis. Our paper focuses on the principle, working, components and applications of wireless capsule endoscopy
In wireless capsule endoscopy, a capsule is being used to record the images of the internal organs. While the capsule provides the best means of viewing the inside of the organ. This device module consists of an image sensor, an illumination, a radio-frequency transmitter and a battery. The device is expelled naturally after approximately 24 hours, if no complications arise. It is a painless procedure that has recently extended to the screening of pathologies of oesophagus and colon. It can be used in an ambulance or hospital setting. The procedure takes about eight hours. The diagnosis made by the Wireless capsule endoscopy (WCE) includes suspicion of small or bowel tumors, celiac disease, polyposis syndromes, abdominal...
