Capsule endoscopy leads the doctors examine the lining of the middle part of one’s gastrointestinal tract,which include the three portion of the small intestine(duodenum , jejunum , ileum). Doctor will give a pill sized video camera for a patient to swallow. This camera has its own light source and takes picture of small intestine as it passess through .These pictures are send to a small recording device patient have to wear on this body.

2. What is capsule endoscopy?
 Capsule endoscopy leads the doctors examine the lining of the middle part
of one’s gastrointestinal tract,which include the three portion of the small
intestine(duodenum , jejunum , ileum).
 Doctor will give a pill sized video camera for a patient to swallow.
 This camera has its own light source and takes picture of small intestine as it
passess through .These pictures are send to a small recording device patient
have to wear on this body.

3. About:
 Capsule endoscopy was first used in humans in 1999.
 The first publication on capsule endoscopy was
published in nature in 2000.

4. How does capsule endoscopy work:
 Eight aerial leads that are attached around the patients
abdomen collecting data.
 Capsule ingested as any other capsule.
 Patient can drink clears immediately,but no solid food
for three hours .
 Attached to the leads is the recorder and the patient
should report back if it stops recording for any reason.

5.  Belt and aerial should be worn for 8 hours after
swallowing or until the recorder stops recording.
 Recorder and aerials are returned , but the capsule is
disposable!
 Images are downloaded and processed prior to
interpretation.

6. Endoscopy procedure:
 Capsule is swallowed by the patient like a
conventional pill.
 It takes images as it is propelled forward by peristalsis.
 A wireless recorder , worn on a belt , recieves the
images transmitted by the pill.
 A computer work station processes the data and
produces a continuous still images.

7. Description:
 The capsule consists of seven optical fibres
 One for elimination and the rest six for collecting
light.
 The tip will illuminate red , green & blue laser light
helping in visuality.
 All this processing together combined will give us
two-dimensional picture helping in diagnosis.
 The images can be retrieved from the recording device
worn around patient waist as a belt.

8. Types of Endoscopic capsules:

9. Inside a capsule camera:

19. Uses:
 Crohn’s Disease.
 Malabsorption Disorders.
 Tumors of the small intestine & Vascular Disorders.
 Ulcerative colitis.

21. Limitations:
 Slow Gastric/Intestinal motility.
 Poorer quality of images as compared to Fiberoptic
scopes.
 The position of the capsule can not be accurately
controlled.
 Potentially obstructed views.
 Morbidly obese patients.
 Interpretation of results are very observer dependent.
 Findings may be of unknown significance or relevence.
