Gastrointestinal Bleeding

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

2 batteries

Radio Frequency Transmitter

Antenna

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

Capsule were intact

Bleeding sites were identified in 11 of the patients
