Q

Define hematoemesis:

A

This is a condition in which a patient is found to be vomiting blood.
This could be:
- Digested blood in the stomach (coffee ground emesis = slow bleeding)
- Fresh unaltered blood: (gross blood and clots indicating rapid bleeding)

Q

Define melena:

A

This is a condition in which faeces are dark and sticky, containing partly digested blood, as a result of internal bleeding. Indicates blood has been in the GI for more than 14 hours.
The more proximal the bleeding site, the more likely melena will occur.

Presentaton:
- black,tarry, semi solid and distinct odor.

Q

Define Hematochezia:

A

Hematochezia is the passage of fresh blood through the anus, usually in or with stools (contrast with melena)

Hematochezia is commonly associated with lower gastrointestinal bleeding, but may also occur from a brisk upper gastrointestinal bleed.

Q

How does a nasogastric lavage work in the diagnosis of bleeding UGIT?

A

A flexible tube is inserted through the nose (goes in via nose to reduce patients likelihood to vomit)
Gastric contents is aspirated and assessed

Used to confirm recent UGITB

  • Coffee ground appearance = recent bleeding
  • Red blood in the aspirate that doesn’t clear = Active bleeding.
  • Lack of blood = Probs isn’t active bleeding but UGITB isn’t excluded

Q

Which 2 lab diagnosis procedures are used in UGITB?

A

CBC with platelet count

  • A complete blood count to asses blood loss
  • Should be taken frequently throughout the day

Hemoglobin value, type and crossmatch blood

  • Hemoglobin should be checked and crossmatched
  • Based on the rate of blood loss
  • Hb level should be monitored serially to asses trends.
  • Unstable trend could mean ongoing haemorrhage requiring intervention.

23
Q

What is the pharmacological treatment of a bleeding peptic ulcer?

A

PPI 80mg IV bolus
Or
8mg per hour for 72 hours via IV infusion

24
Q

What is the endoscopic treatment of a bleeding peptic ulcer?

A
Injection of epinephrine 
Mono polar coagulation
Bipolar coagulation
Heater probe 
Hemoclips
Argon plasma coagulation
25
Q

What is the surgical treatment of a bleeding peptic ulcer?

A

Used when endoscopic treatment fails

- under-running.

26
Q

What is under running in peptic ulcers surgery?

A

This laparoscopic procedure involves making a 11mm port just under the xiphisternum. 2 to 3 stitches are passed deep into the ulcer and the sutures are tied tight to stop the bleeding.

27
Q

What is the method of choice for a UGITB?

A

Endoscopy.

28
Q

When should endoscopic therapy be scheduled?

A

For cases with lesions that are actively bleeding
Non-bleeding visible vessels
To ulcers with an adherent blood clot

29
Q

When shouldn’t endoscopic therapy be scheduled, due to excellent prognosis of the type of peptic ulcer being formed?

A
  • Black or red spots
    • A clean ulcer base with oozing
      Do not require endoscopic intervention since these lesions have an excellent prognosis without intervention.
30
Q

True or false: Adrenaline should not be used as monotherapy for the endoscopic treatment of non-variceal UGIB

A

True:

Adrenaline should not be used as mono-therapy for the endoscopic treatment of non-variceal UGIB

31
Q

Give 3 treatment options for the treatment of Non-variceal bleeding:

A
  1. Mechanical method- I.e. Clips with or without epinephrine
  2. Thermal coagulation with epinephrine
  3. Fibrin or Thrombrin with adrenaline
32
Q

When Should radiology be offered as a treatment method?

A

In unstable patients who rebleed after endoscopic treatment.
Should radiology fail to work, refer patient for surgery

33
Q

What are 5 conditions that qualify a patient for surgery

A
  1. Persistent hypotension
  2. Failure of medical or endoscopic treatment
  3. Coexisting condition i.e. perforation, obstruction, malignancy
  4. If transfusion is required
  5. Recurrent hospitalization.
34
Q

What are 3 types of operations?

Note these are dependent on the site and bleeding lesions.

A
  1. Duodenal ulcers are treated by under running with/without pyloro-plasty.
  2. Gastric ulcers are treated by under running
    • A biopsy should be taken too, to exclude carcinoma
  3. Local excision or partial gastrectomy will be required.
35
Q

What medication is issued for variceal bleeding?

A
  1. Terlipressin
    Should be stopped:
    - Once definitive homeostasis is reached right.
    - Or after 5 days unless it is needed for something else.
  2. Prophylactic Antibiotic therapy
  3. Balloon tamponade should be considered as a temporary salvage treatment for uncontrolled variceal haemorrhage
36
Q

What 3 treatment procedures are used for bleeding oesophageal varices?

A
  1. Band ligation
  2. Stent insertion
  3. Trans-jugular intrahepatic portosystemic shunts (TIPS) should be considered if band ligation for bleeding oesophageal varices does not work.
37
Q

What 3 treatment procedures are used for bleeding gastric varices?

A
  1. Endoscopic injection of N-butyl-2-cyanoacrylate

2. Trans-jugular intrahepatic portosystemic shunts (TIPS) should be offered if N-butyl-2cyanoacrylate does not work.
