Is any type of bleeding that occurs in the gastrointestinal tract from the pharynx to the rectum
Treatments involves proton pump inhibitors, octeotride, and antibiotics (Certain Cases)
There is also an emphasis on resuscitation by infusion of intravenous fluids and blood transfusion.
Gastrointestinal Bleeding is usually discovered by Upper endoscopy, Colonoscopy, or Capsule Endoscopy.
Upper endoscopy & Colonoscopy
Upper endoscopy-Procedure that visualizes the uses upper part of the gastrointestinal tract up to the duodenom
Colonoscopy- examination of the large bowl and the distal part of the small bowl.
What is Capsule Endoscopy? A way to record images of
the digestive tract through a small camera in the pill.
It is the size and shape of a pill. (11x26mm)
Created in Israel.
Adopted in the U.S
Approved by the U.S Food & Drug Administration 2001
StructureContains Lens
4 emitting diodes
Color camera

Methods1) Patient are required to fast for
12 hours before taking the capsule
2) Patients drink a Simethicone Solution
3) Thirdly, the patients have a belt tied around their waste. This belt contains a sensor.
3)Next they swallow the capsule. After they swallow it they are required to not have anything in their mouths for 4 hours.
Methods Continued
4)After 8 hours sensor is removed from them.
5) Capsule is then digested from the system.
6) The recordings are then downloaded to a computer software from the belt.
Pros & Cons
Identifies bleeding in the small bowel that can not be reach
High Resolution Images
There are no therapeutic capabilities for it.
Becoming impacted into a region due to inflammatory bowl disease, surgical adhesions etc.
Results
22 Patients were tested
Capsule had a transit time of 257 minutes in the small intestine
Out of the 22 patients tested only 21 capsules were retrieved
