Q

What factors make up the Rockall score and what does it predict?

A

Factors: age, ‘shock’ (SBP <100, HR >100), comorbidities

predicts risk of further bleeding and death in pts hospitalized for UGIB

** this is a pre-endoscopic risk score **

Q

What factors make up the Blatchford score and what does it predict?

Anything interesting (from a disposition perspective) re the Blatchford score?

A

Factors:
labs (Hgb - M < 13, F < 12; BUN >18.2)
clinical (SBP <110, sex, HR >100, melena, recent syncope, h/o liver dz, cardiac failure)

predicts risk of intervention (transfusion, endoscopic or surgical therapy) and death

If Blatchford score = 0, may consider d/c from ED w/o inpatient endoscopy

Q

what are the instructions for using pre-endoscopic erythromycin?

why would you use it?

A

250mg IV given 30 min before EGD

may consider to improve diagnostic yield and to decrease need for repeat EGD (conditional rec; mod qual ev)

However, no improvement in clinical outcomes (transfusion burden, hospital stay, need for surgery)

Q

What are the pros and cons of PPI in acute UGIB?

A

PROS:

  • decrease # of pts w/ high risk stigmata (active bleeding, non-bleeding visible vessel, adherent clot) at index EGD (conditional rec; high qual ev)
  • if EGD will be delayed or not done, IV PPI may reduce further rebleeding (conditional rec; mod qual ev)

CONS:
- doesn’t improve risk of death, rebleeding, or surgery

Q

After EGD, what do you do about the PPI?

A

if no ulcers or erosions on EGD, stop PPI

otherwise. ..
- for pts w/ high risk stigmata of recent hemorrhage (SRH), PPI infusion decreases rebleed rate, need for surgery, and death
- for the oozing subgroup, however, PPI infusion didn’t change risk of rebleeding. may not need PPI infusion for this subgroup
- intermittent PO PPI may be equiv to IV infusion x 72hr

Q

what defines a high risk pt presenting w/ UGIB?

when should high risk pts have EGD done?

A

tachycardic, hypoTN, hematemesis, Blatchford >= 12.

For high risk pts, early EGD (w/n 12 hrs of presentation) is a/w better clinical outcomes (fewer transfusions, shorter hospitalization, decreased mortality) (conditional rec; low qual)

risk of re-bleed 22%
risk of death 7%

TX: IV PPI x 72hr. Vigorous irrigation of clots is recommended to more accurately assess underlying SRH

may consider endoscopic tx if clot is resistant to vigorous irrigation and pt has features possibly a/w high risk of rebleed (older, comorbidities, already inpt setting at onset of bleed) (conditional rec; mod qual ev)

24
Q

tx?

A

flat pigmented spot

Forrest classification 2C
prevalence 16%
risk of re-bleed 10%
risk of death 3%

TX: no endoscopic tx. switch to PO PPI once daily to heal the ulcer (strong rec; high qual ev)

25
Q

Forrest classification, prevalence, risk of re-bleed, and risk of death for: clean base

tx?

A

clean base

Forrest classification 3
prevalence 55%
risk of re-bleed 5%
risk of death 2%

TX: no endoscopic tx. switch to PO PPI once daily to heal the ulcer (strong rec; high qual ev)

26
Q

what are the categories of endoscopic tx options?

A
  • thermal
  • injection
  • thrombin (+/- fibrinogen) - not recommended as first line
  • clips (pair w/ epinephrine)
27
Q

what are the types of thermal tx? any special benefits to each of them?

A

THERMAL OPTIONS:

  • bipolar electrocoagulation + (pair w/ epinephrine)
  • heater probe +
  • monopolar electrocoagulation x
  • argon plasma coagulation x
  • laser x

+ decreases further bleeding, need for surgery, and mortality (strong rec; high qual ev)

x not recommended as first line tx

28
Q

what are the types of injection tx?

A

INJECTION OPTIONS:

  • epinephrine
  • sclerosants + (absolute ethanol*, polidocanol, ethanolamine)

+ pair w/ epinephrine
* decreases further bleeding, need for surgery, and mortality (strong rec; high qual ev)

29
Q

how does epinephrine monotherapy compare w/ other endoscopic tx for initial hemostasis? for rebleed risk? for need for surgery?

what are the directions for using epi?

A

equally effective for achieving initial hemostasis for active bleeding compared to other endoscopic options

HOWEVER, epi mono is inferior for reducing rate of rebleeds and surgery.

*** THEREFORE, if using epi, must combine w/ another modality

use as 1:10,000 or 1:20,000 solution

FOR ACTIVE BLEEDING: inject until bleeding slows or stops

FOR NONBLEEDING SRH: inject in all 4 quadrants next to SRH in ulcer base

TIP:
Preinjecting epi before other tx may help slow or stop bleeding, allowing improved visualization for application of the other tx. Preinjecting epi before clot removal may reduce rate of several bleeding caused by clot removal

30
Q

what’s a downside of using sclerosant?

A

high volume of sclerosant may cause tissue necrosis

31
Q

directions for using absolute alcohol?

A

use in aliquots of 0.1-0.2mL (max 1-2mL). must pair with epi.

32
Q

which is superior: thermal tx or sclerosant? why?

A

thermal tx > sclerosant

thermal tx requires fewer urgent interventions

33
Q

What patient population might you consider using clips? what’s the theoretical advantage?

A

theoretical benefit of not inducing tissue injury, so may be preferred for pts on antithrombotics or in those getting re-scoped for rebleeding.

place clips on bleeding site and on either side of the SRH to seal the underlying artery.

34
Q

directions for using bipolar electrocoagulation

A

put endoscope tip as close as possible to bleeding ulcer

15W, 8-10 sec applications

apply multiple times in ulcer base on and around SRH until bleeding stops, vessel is flattened, and base is whitened

35
Q

why do we do PPI infusion for pts w/ high risk SRH?

A

for pts w/ high risk SRH, PPI infusion decreases rebleed, surgery, and death

36
Q

How do you disposition pts w/ PUD UGIB?

A

for pts w/ high risk SRH, generally should be hospitalized x 3 days assuming no rebleeding and no other reason for hospitalization. They may take clear liquids soon after endoscopy (conditional rec; low qual ev)

for pts w/ clean-based ulcer:
regular diet + d/c home assuming hemodynamic and hgb stability (strong rec; mod qual ev)

37
Q

why do we say pts w/ high risk SRH should be hospitalized x 3 days?

A

older studies show 95% of rebleeds occur w/n 3 days. More recently, randomized trial showed 24$ of rebleeds were after day 3

38
Q

why do we recommend clear liquids soon after endoscopy (granted, it’s a conditional rec w/ low qual ev)

A

since many pts will need urgent interventions for rebleeding, and clear liquids allow sedation/anesthesia w/n 2 hrs after last ingestion

39
Q

What risk category are Mallory Weiss tears?

A

Mallory Weiss tears are considered low risk for rebleeding

40
Q

Long term prevention of recurrent bleeding ulcers:

if H pylori is discovered, what are the tx steps?

A

tx H pylori, confirm eradication (after at least 1 month after H pylori tx is complete; must d/c PPI at least 2 weeks before testing for eradication), and then can stop antisecretory therapy (unless pt needs NSAIDs or antithrombotics) (strong rec; high qual ev)

41
Q

Long term prevention of recurrent bleeding ulcers:

if NSAID is the cause, what are the tx steps?

A

d/c NSAID if possible. If can’t d/c, choose cox2 selective inhibitor at lowest effective dose + daily PPI (strong rec; high qual ev)

42
Q

Long term prevention of recurrent bleeding ulcers:

if low dose ASA-associated bleeding, what are the tx steps?

A

re-assess need for aspirin.

if indication is secondary prevention, then resume ASA as soon as bleeding ceases, w/n 7 days + do long term daily PPI

If indication is primary prevention, likely d/c antiplatelet tx (conditional rec; mod qual ev)

43
Q 
Long term prevention of recurrent bleeding ulcers:
if idiopathic (non H pylori, non-NSAID) ulcers, what are the tx steps?
A

tx w/ long term antiulcer tx (e.g. daily PPI) (conditional rec; low qual ev)
