tablet endoscopy is a technology that uses a swallowed video pill to take pictures of the inner of the esophagus, stomach, and small intestine. for capsule endoscopy, the intestines are first cleared of residual meals and bacterial debris with using laxatives and/or purges very similar to the laxatives and purges used earlier than colonoscopy. a huge capsule-large than the most important tablet-is swallowed with the aid of the patient. the tablet carries one or video chips (cameras), a mild bulb, a battery, and a radio transmitter. as the tablet travels via the esophagus, stomach, and small intestine, it takes pics hastily. the photos are transmitted by way of the radio transmitter to a small receiver this is worn on the waist of the affected person who is undergoing the pill endoscopy. on the quit of the procedure, about 8 hours later, the snap shots are downloaded from the receiver into a computer, and the images are reviewed by a medical doctor. the capsule is handed by the affected person into the toilet and flushed away. there may be no want to retrieve the pill!
at the same time as the pill presents the first-class approach of viewing the interior of the small intestine, there are numerous inherent obstacles and troubles with its use, the most important of that's that the pill does no longer permit for remedy. different troubles encompass:
abnormalities in some regions of the intestine are ignored due to speedy transit of the pill and blurred, uninterpretable pix. the photos can also be blurred via retained stool of meals particles. consequently the importance of an amazing bowel coaching previous to the pill endoscopy.
at instances, transit is so sluggish that the tablet examines most effective a part of the small gut earlier than the battery fails. the battery life is ready eight hours.
if abnormalities are found that require surgical resection or further investigation, it could be difficult to decide wherein inside the small gut the abnormality is and thereby assist direct therapy.
if there are slim regions due to scarring (strictures) or tumors inside the small intestine, the tablet can get stuck in the slender location and motive an obstruction of the gut that calls for surgical elimination of the pill. (for this reason, in sufferers who're suspected of having a stricture, a self-dissolving, dummy capsule is swallowed first. if the dummy tablet sticks, it may be visible on an x-ray of the stomach and the vicinity of the stricture determined. as it dissolves with time, however, the obstruction from the pill will clear up without surgical operation, and the real pill will not be used.)
eventually, reviewing the tens of hundreds of pictures is very time consuming for the conscientious health practitioner.
tablet endoscopy continues to improve technically. it has revolutionized prognosis with the aid of supplying a sensitive (capable of perceive diffused abnormalities) and simple (non-invasive) method of examining the inside of the small gut. a few common examples of small gut sicknesses diagnosed through pill endoscopy encompass:
angiodysplasias (collections of small blood vessels located just below the inner intestinal lining which can bleed intermittently and motive anemia)
small intestinal tumors consisting of lymphoma, carcinoid tumor, and small intestinal cancer
crohn's sickness of the small gut
