Basics of GI Bleeding

Hepatology
Early July on ART 6W…
• Overnight admit
– 69 yo male with recent melena and Hgb to 5 g/dl
– Prior perforated gastric ulcer with Graham patch
– Recent hemicolectomy for colonic signet ring
adenoCA
– EGD two days prior with large nonbleeding ulcer
extending from lesser curvature to incisura
– Was in rehab for a few hours before hematemesis
During Rounds
• “This patient was admitted for hematemesis”
• [Pause, quick glance at patient in room]
• “And he’s having active hematemesis now!!”
What do you do now?
•
•
•
•
•
•
•
Assess hemodynamics
Ensure large bore IV access
Consider PPI infusion
Could we be dealing with varices?
Key labs: CBC, INR, BUN
Think about NG lavage
Don’t think about Fecal Occult
His EGD
Definitions
• Inpatient
– Overt
• Outpatient
– Occult
– Obscure
• UGIB
• LGIB
Magnitude
• Acute UGIB estimated to be 400,000 U.S.
hospital admissions per year1
• 80-90% of UGIB is nonvariceal2
• Peptic ulcer bleeding
– Affects patients > 60 years old3
– 5-10% mortality 2,4
– $2B in U.S. health care spending per year5

Initial Steps
•
•
•
•
•
Estimate hemodynamics
Volume resuscitate
Rectal exam
Identify high risk patients
Early endoscopy is key
– Within 24 hours
– High risk window 72 hours from presentation
Initial Steps
•
•
•
•
Understand anti-coagulation history
Assess level of care and airway
Make a differential diagnosis
Find old endoscopy reports

UGIB: Brief DDx
• Peptic ulcer disease
– H. pylori
– NSAIDs
– Malignancy
•
•
•
•
Mallory-Weiss tear
Erosive esophagitis
Erosive gastritis
Esophageal ulcers
UGIB: Brief DDx
• Vascular malformations
– Angiodysplasia in CRI
– Dieulafoy’s lesion (submucosal arteriole)
– GAVE
– PHG
• Miscellaneous
– AE fistula
– Pancreatic pseudoaneurysm
– Hemobilia
Varices
• Some adjustments to protocol
– Octreotide drip
• Decrease splanchnic blood flow
• Reduce portal pressure
– Antibiotics
– Lower transfusion requirement
– Correcting coagulopathy if appropriate
– Intubate
LGIB: Brief DDx
•
•
•
•
Diverticulosis
Angiodysplasia
Neoplastic disease
Colitis
– Ischemia, infection, XRT, IBD
• Internal hemorrhoids
• Solitary rectal ulcer
• UGIB
Risk Stratification
• Important way to predict who might do poorly
• Rockall Score
– Age
– Shock (HR, BP)
– Coexisting illness
– Add endoscopic component
• Diagnosis
• High risk stigmata

Endoscopic Stigmata of Bleeding Peptic Ulcer, Classified as High Risk or Low Risk.

Basic Endoscopic Therapy
• Injection AND
– Thermal (e.g. heater probe, APC) OR
– Mechanical (e.g. clip)
• Thermal or mechanical alone
• For varices,
– Band ligation
Why PPI’s?
• Goal of PPI therapy is to raise the gastric PH
• High dose PPI infusion decreases basal and stimulated
acid secretion by parietal cells
• Cochrane meta-analysis that included 6 RCT from 19922007 found that IV PPI prior to endoscopy did NOT
experience any statistically significant differences in
outcomes of mortality, rebleeding, or progression to
surgery.
• However, analysis did show that PPI therapy resulted in
significantly reduced rates of high risk stigmata
identified on endoscopy and need for endoscopic
therapy.

Post-Endoscopy
• High risk lesions
– PPI infusion for 72 hours after endoscopic
hemostasis
– Technically
• Can advance diet to clears after 6 hours (if
hemodynamic instability)
• Can go to oral PPI after infusion complete
• Discuss with GI consultant
– No role for repeat endoscopy in 24 hours; relook if
rebleed
Post-Endoscopy
• Varices
– Octreotide infusion for up to 5 days in conjunction
with band ligation1
• Result of meta-analysis
• 5 day period highest for re-bleed
– Antibiotics for 1 week
• For non-variceal bleeding
– H pylori testing (preferably from mucosal biopsy)

What if Endoscopy Fails?
• IR
– Tagged RBC scan
• Bleeding > 0.1 ml/min
– Angiography
•
•
•
•
Need localization
Renal contrast load
Bleeding 0.5-1.5 ml/min (CT angiography)
Can be therapeutic
– Embolization
What if Endoscopy Fails?
• Surgery
– Uncontrolled bleeding
– Recurrent diverticular bleeding
– Get on board early

Summary
While “all bleeding eventually stops…”
• Assess
• Resuscitate
• Risk-stratify
• Form a differential diagnosis
• Be particularly vigilant in the first 24 hours
