` Bleeding from a source proximal to the ligament of

Trietz .

` Upper: Lower GI bleeding = 5:1

` Incidence: 50-100 per 100,000 pts.

` 100 per 100,000 hospital admission.

` 30% pts are older than 65 years 80% are self-limited.

20% of pts who have recurrent bleeding (within

48-72 hrs) have poor prognosis.

1) Peptic ulcer disease - most common

A) duodenal ulcers 29%

will rebleed in 10% of cases within24-48h

B) gastric ulcers 16%

more likely to rebleed

C) stomal ulcers <5%

` 2) Erosive gastritis, esophagitis, duodenitis

some causes are ETOH, ASA, NSAID¶s

` 3) PORTAL HYPERTENSION RELATED

esophageal varices gastric varices

portal hypertensive gastropathy

` 4) Mallory-Weiss syndrome ± longitudinal

region

` Get to patient¶s bedside, assess ABC` Can the patient protect his airway?

Does he need to be intubated?

` Is the patient hemodynamically unstable?

Is he in hemorrhagic shock?` 2 large bore IV, Bolus 2L fluids, Type & Cross

blood, send CBC & Coags

` Place patient on O2 & continuous monitor

Place an NGT and lavage with NS To confirm if the bleeding source is upper GI

look for need for blood transfusion

Nuclear Medicine Techniques in the

Diagnosis of Gastrointestinal Bleeding

After the intravenous injection of either sulfur colloid

la eled red lood cells, images are made over theupper and lower a domen

.Bleeding rates as low as 0.1 ml per minute may e

detected.

H. pylori eradication

1st line

x PPI + clarithromycin (500mg OD) +

amoxicillin (1000mg BID) or metronidazole(500mg) if patient has a penicillin allergy

2nd linex PPI + ismuth + metronidazole + tetracycline

INJECTION THERAPY

Adrenaline

The ethanol is injected slowly, in amounts of

0.1 to 0.2 ml per injection, at three or four sites

surrounding the leeding vessel and 1 or 2 mm

from the vessel .

Sclerosants

1% polidocanol, alcohol and ethanolamine .

Polidocanol causes haemostasis y inducing

owel wall spasm and early oedema with

su sequent inflammation and throm osis of

the vessel.

A solute alcohol stops leeding y causing

rapid dehydration and fixation of the tissue,

thus o literating the leeding vessel.

Procoagulants (Throm ogenic Agents)

Human throm in and fi rin sealant

Technique

video-gastroscope (3.7 or 4.2mm workingchannel) with a disposa le 23 or

25 gauge sclerotherapy needle is

recommended.

4-16 ml of 1:10,000 adrenaline,

in 0.5ml aliquots is injected into and around

the leeding point until the leeding stops

Thermal Modalities

Contact and non-contact methods

. Monopolar elect rocoag ulationDue to an unpredicta le depth of coagulation,

monopolar electrocoagulation is no longer recommended

M ul ti polar elect rocoag ulation

Consists of 3 pairs of electrodes arranged in a linear array at the tip and connected to a power generator.

The flow of the electrical current is limited thus

avoiding pro lems with grounding and a errant current.

Thermal non-contact methods

Argon Plasma Coagulation

Argon plasma coagulation (APC) is a special

electrosurgical modality in which high

frequency electric current is conducted

µcontact-free¶ through ionized and thus

electrically conductive argon (argon plasma)into the tissue to e treated.
