3. Upper Gastrointestinal Bleeding
• Presents with:
• Hematemesis (bright-red or “coffee-ground” emesis)
• Melena (black, tarry-appearing stool)
• Or very rarely hematochezia or bright red blood per rectum due to
briskly UGIB, which is associated with increased mortality.
4. UGIB: Causes
• 80% is due to 4 causes:
• PUD
• EV
• Esophagitis
• Mallory-Weiss tear.
• Bleeding in 80% stops spontaneously
• 20% have persistent or recurrent bleeding, increasing mortality.
5. UGIB: Causes
• Slow &/or chronic bleeding:
• Suggested by history of IDA.
• Typical of erosive disease: tumor, esophageal ulcer, portal
hypertensive gastropathy, Cameron lesion (5%, eroded large hiatal
hernias)& angiodysplasia.
6. UGIB:Causes
• Causes of brisk&/or severe upper GIB that increase mortality.
• Peptic ulcer
• Esophagogastric varices
• Dieulafoy lesion
• Aortoenteric fistula
• Hemobilia: usually from liver or biliary procedural complication or
gallstone complications, tumors &angiodysplasia.
• Hemosuccus pancreaticus: (pseudoaneurysm/aneurysm)
• Neoplasm
• Esophageal lesions
• Gastric GIST
7. UGIB : evaluation by History
• H/O chronic alcohol abuse: a clue to the possibility of VH.
• Chronic dyspepsia: PUD.
• NSAIDs use: PUD.
• H/O Aortic aneurysm repair: aortoenteric fistula.
8. UGIB : evaluation by History
• Predictors of severe GIB are:
• Hematemesis
• Comorbidities (such as cirrhosis or malignancy)
• HD instability
• Hb <8 g/dL (80 g/L).
• bleeding source.
9. UGIB : evaluation aims
• Assessing severity.
• Differentiating upper from lower GIB sources.
• Determining the need for interventions.
10. Evaluation: assessing severity
• Outpatient management is usually appropriate when the following
criteria are met:
• BUN<18.2 mg/dL (6.5 mmol/L)
• Normal Hb
• Systolic BP>109 mm Hg
• PR< or equal to 100/min
• Absence of: melena, Syncope,Liver disease,Cardiac failure.
12. Evaluation: assessing severity
• Severity scoring:
• Best validated &most useful is Glasgow-Blatchford score (0-23), of 9
variables: BUN (0-6 points), Hb (0-6), SBP(0-3), PR(0-1), melena (0-
1), syncope (0-2), hepatic disease (0-2 points)& HF(0-2).
• Has a nearly 100% NPV for severe GIB& the need for hospital-based
intervention (blood transfusion, endoscopic therapy, TC arterial
embolization, surgery).
• UGIB is most reliably predicted by 4 variables: melena, NGT with
blood or “coffee grounds,” BUN/ Cr > 30 & absence of blood clots in
the stool.
13. UGIB Management:
• 1. Pre-endoscopic care (resuscitation, hemodynamic monitoring, PPI
therapy, attention to coagulopathy)
• 2. Early endoscopic evaluation (with excellent endoscopic vision) &
treatment.
• 3. Postendoscopic care & risk reduction.
14. UGIB Management:
• Pre-endoscopic Care:
• 1.Resuscitated with crystalloids to reach physiologic endpoints (PR
<100/min, SBP>100 mm Hg&resolution of orthostasis).
• 2.Blood transfusion indicated:
• A. HD instability &ongoing bleeding or susceptibility to
complications from hypoxia (for example IHD).
• B. Target Hb < 7 g/dL, if HD stable with no active or massive
bleeding.
• 3.Early (pre-endoscopic) PPI does not improve clinical outcomes
(bleeding, surgery, mortality) but is safe & reduces the likelihood of
detecting ulcers with high-risk stigmata & need for endoscopic trt.
• 4.Coagulopathy (INR >1.5) corrected with FRP not vit K (delayed full
therapeutic effect) in actively bleeding receiving anticoags.
• 5.Octreotide & antibiotics should be given before endoscopy for
suspected variceal bleeding.
15. UGIB Management:
• NGT is not required for diagnosis, prognosis, visualization, or
therapeutic effect.
• Routine use of prokinetics is not recommended except when
patients are suspected of having large amounts of blood in the
UGIT; in such cases, erythromycin can be given prior to upper
endoscopy.
16. UGIB Management:
• Endoscopic treatment:
• Upper endoscopy within 24 hours of presentation in patients with
features of UGIB.
• Endoscopy within 12 hours is generally recommended only for
patients with suspected variceal bleeding.
• Low-risk ulcers not requiring endoscopic intervention are clean-
based or have a non-protuberant pigmented spot.
• Intermediate-risk ulcers have adherent clots & should be vigorously
irrigated to dislodge the clot & reclassified based on appearance.
• High-risk ulcers that require endoscopic treatment: active arterial
spurting or a non-bleeding visible vessel &.
• Routine second-look endoscopy is not required after UGIB unless
rebleeding occurs or the initial examination was incomplete.

18. UGIB Management:
• Post-endoscopic Care & Risk Reduction:
• Post endoscopic PPI improves outcome after endoscopic
interventions.
• PUD tested for H pylori &If positive, eradication done &confirmed.
• If negative, retesting done with an alternative method BZ of false-
negative results with bleeding, PPI, or concomitant antibiotics.
• Aspirin should be resumed within 3 - 5 days for patients with
established CVD.
• Long-term PPI may not be necessary for aspirin users who undergo
H. pylori testing &eradication.
• Long-term, daily PPI should be offered to aspirin users who are H.
pylori negative or those who use concomitant NSAIDs,
anticoagulants, glucocorticoids, or other antiplatelets.
19. Variceal bleeding Management:
• Octreotide / telipresin infusion & antibiotics are given even if this is
suspected.
• FLuid resuscitation is preferred with crystaloids.
• Endoscopic intervention can be done safely even with INR up to 2.5
& above that, correction done with FFP.
• Endoscopic band ligation is preferred over sclerotherpay for acute
esophageal variceal bleeding.
• For bleeding gastric varices cyanoacrylate sclerotherpay is preferred
over band ligation.
• When the above measures fail, temponade with esophgeal balloons
as Baltimore-Sengestaken tube is used as bridge to more definitive
therapies as TIPS or surgery.
• NS Beta-blockers are used after the control of the bleeding.

23. LGIB:
• Typically occurs in elderly.
• Presents with hematochezi; acute bright red blood per rectum or
red- or maroon-colored stool.
• HD instability is less common but, if present, raises the possibility of
a briskly bleeding UGI source.
28. SIB or Obscure GIB
• Relatively uncommon ; 5–10% of GIB.
• with advances in SI imaging(VCE, deep enteroscopy& radioimaging)
the cause of bleeding in SI identified in most patients.
• OGIB should be reserved for patients in whom a source of bleeding
cannot be identified anywhere in the GI tract.
• SIB should be considered in patients with GI bleeding after
performance of a normal upper & lower endoscopic exams.
• Second-look exams using upper endoscopy, push enteroscopy&/or
colonoscopy can be performed if indicated before SB evaluation.
• VCE should be considered a first-line procedure for SIB& should be
performed before deep enteroscopy if there is no contraindication.
• Any method of deep enteroscopy can be used when endoscopic
evaluation& therapy are required.
29. SIB or Obscure GIB
• CTE should be performed in patients with suspected obstruction
before VCE or after negative VCE exams.
• When there is acute overt hemorrhage in the unstable patient,
angiography should be performed emergently.
• In patients with occult hemorrhage or stable patients with active
overt bleeding, multiphasic computed tomography should be
performed after VCE or CTE to identify the source of bleeding &
guide further management.
• If a source of bleeding is identified in the small bowel that is
associated with significant ongoing anemia and/or active bleeding,
the patient should be managed with endoscopic therapy.
• Conservative management is recommended for patients without a
source found after SB investigation, whereas repeat diagnostic
investigations are recommended for patients with initial negative
SB evaluations & ongoing overt or occult bleeding.
