Upper gastrointestinal bleeding is gastrointestinal bleeding in the upper gastrointestinal tract, commonly defined as bleeding arising from the esophagus, stomach, or duodenum. Blood may be observed in vomit (hematemesis) or in altered form in the stool (melena). Depending on the severity of the blood loss, there may be symptoms of insufficient circulating blood volume and shock. As a result, upper gastrointestinal bleeding is considered a medical emergency and typically requires hospital care for urgent diagnosis and treatment. Upper gastrointestinal bleeding can be caused by peptic ulcers, gastric erosions, esophageal varices, and some rarer causes such as gastric cancer.
The initial assessment includes measurement of the blood pressure and heart rate, as well as blood tests to determine hemoglobin concentration. In significant bleeding, fluid replacement is often required, as well as blood transfusion, before the source of bleeding can be determined by endoscopy of the upper digestive tract with an esophagogastroduodenoscopy. Depending on the source, endoscopic therapy can be applied to reduce rebleeding risk. Specific medical treatments (such as proton pump inhibitors for peptic ulcer disease) or procedures (such as TIPS for variceal hemorrhage) may be used. Recurrent or refractory bleeding may lead to need for surgery, although this has become uncommon as a result of improved endoscopic and medical treatment.

Approach to Management of Upper Gastrointestinal (GI) Bleeding
1.
Approach to Upper GI Bleed
Seminar – November 30th 2015
Presenter: Dr.Arun Vasireddy
2. Case Senario
A 73 yr old man presented to the ER with 5 day H/O passing black tarry
stools and abdomen pain.
C/o postural dizziness since 1 week. c/o Indigestion
Stools are normal coloured, c/o constipation intermittently
H/o weight loss since 1 yr (6 kg loss)
Pt had PVD since 2 yrs for which he takes aspirin daily.
Consumes 30-40 units alcohol/week.
In the ER, the Pt had giddiness and had vomited dark stained material
looking like coffee grounds.
3. Vitals: bp- 90/60 mm hg (postural drop of 30mm hg)
HR-120/min , Moderated dehydration +, conjunctival pallor+
CVS – Loud ejection systolic murmer radiating to carotids
RS – B/l airway clear
PA – epigastric tenderness+ no organomegaly/palpable mass
Rectal exam revealed enlarged prostrate & fresh melaena + , no
fresh rectal bleeding
EKG – sinus tachycardia with LVH, no evidence of ischemia
Diagnosis…..?

6. Epidemiology
UGIB vs LGIB= 5:1
Incidence: 170 patients/ 1,00,000 population /year.
40% due to peptic ulcer(Most common).
80% are self-limited.
Pts on anti platelet therapy has two fold increase in bleed as
compared to normal ones.
20% of pts of moderate to high risk, who have recurrent
bleeding (within 48-72 hrs) have poor prognosis.
The mortality rate is 5% to 10% for severe UGI bleed.
10. Peptic Ulcers
PATHOGENESIS:
Infection/irritation leads to disruption of the mucous barrier and has
a direct inflammatory effect on gastric and duodenal mucosa.
As the ulcer burrows deeper into the gastroduodenal mucosa,
weakening and necrosis of the arterial wall, development of a
pseudoaneurysm. weakened wall ruptures, hemorrhage
H.PYLORI: NSAIDS:
* involves antrum * gastric ulcers > common
*duodenal ulcers * 15-45% patients develop
* 25% indians have ulcers on regular use
lifetime risk of peptic ulcer

12. MALLORY WEISS SYNDROME /TEARS
Mucosal or sub-mucosal lacerations that occur
at the gastro-esophageal junction and usually
extend distally into a hiatal hernia .
Typically have a history of recent non-bloody
vomiting with excessive retching followed by
hematemesis..
Endoscopy usually reveals a single tear that
begins at the gastro-esophageal junction and
extends several millimeters distally into a hiatal
hernia sac/within cardiac portion of stomach.
13. HAEMORRAGIC OR EROSIVE GASTRITIS
Stress related mucosal injury
Occur mostly in extremly sick patients
Major Trauma
Post Major Surgery
3rd Degree burns
Major intracranial disease
Severe medical illness (Ventilator dependence, coagulopathy)
Significant bleeding probably does not develop unless ulceration
occurs.
Intravenous H2-receptor antagonist is the treatment of choice.
Sucralfate also effective
Aspirin and NSAIDS
Half of the patient who chronically ingest NSAIDS have Erosions. (15 –
30% have Ulcers)
Most Frequently and severely affected site is gastric antrum.
14. PORTAL GASTROPATHY
On endoscopic examination mucosa is engorged and friable.
Portal hypertensive gastropathy (PHG) is caused by increased
portal venous pressure and severe mucosal hyperemia that
results in ectatic blood vessels in the proximal gastric body and
cardia and oozing of blood.
Less severe grades of PHG appear as a mosaic or snake skin
appearance and are not associated with bleeding.
Usually, patients with severe PHG present with chronic blood
loss, but they occasionally can present with acute bleeding.
15. Dieulafoy's lesion
It is a large (1- to 3-mm) submucosal artery that protrudes through the mucosa.
It is not associated with a peptic ulcer, and can cause massive bleeding.
It usually is located in the gastric fundus, within 6 cm of the gastroesophageal
junction.
Dieulafoy's lesion can be difficult to identify at endoscopy because of the
intermittent nature of the bleeding.
the overlying mucosa may appear normal if the lesion is not bleeding.
16. Endoscopic Doppler ultrasound has been used
to help identify a Dieulafoy's lesion that is not
visualized on endoscopy.
If a Dieulafoy's lesion is found and treated, the
site is marked with submucosal injection of ink to
tattoo the area in case of rebleeding and the
need for retreatment.
Endoscopic hemostasis of a Dieulafoy's lesion
can be performed with injection therapy, a
thermal probe, or clip device or by band ligation.
Rebleeding after successful hemostasis appears
to be rare.
17. Gastric AntralVascular Ectasia
Gastric antral vascular ectasia (GAVE), also described as
watermelon stomach.
Characterized by rows or stripes of ectatic mucosal blood
vessels that emanate from the pylorus and extend proximally
into the antrum .
18. Etiology unknown.
GAVE is most commonly reported in older women and also
seems to be more common in patients with end-stage renal
disease
GAVE has been associated with cirrhosis and scleroderma.
Patients with GAVE who do not have portal hypertension
demonstrate linear arrays of angiomas (classic GAVE).
Pts with portal hypertension have more diffuse antral
angiomas.
19. Aortoenteric fistula
Bleeding is usually acute and massive, with a high mortality rate(30-
100%).
The A-E fistula is a communication between the native abdominal
aorta (usually an atherosclerotic abdominal aortic aneurysm) and,
most commonly, the third portion of the duodenum.
Often, a self-limited herald bleed occurs hours to months before a
more severe, exsanguinating bleed.
Secondary aortoenteric fistula between the third portion of the
duodenum and the proximal end of the graft but may occur elsewhere
in the GI tract.
The fistula usually forms between three and five years after graft
placement.
20. Cameron's Lesions
Cameron's lesions are linear erosions or ulcerations in the proximal stomach
at the end of a large hiatal hernia, near the diaphragmatic pinch.
Cameron's lesions are thought to be caused by mechanical trauma and local
ischemia as the hernia moves against the diaphragm and only secondarily by
acid and pepsin.
May present as slow GI bleeding and iron
deficiency anemia.
The long-term medical management is usually
with iron supplements and an oral PPI.
21. VARICES
Consequence of Portal HTN.
The initial factor in portal HTN is the increase in vascular resistance to portal
blood flow.
This will lead to structural distortion (underlying disease) and active
contraction of portal/septal cells (hepatic cells,myofibroblasts) in portal
venules. (the dynamic component).
This will lead to development of porto-systemic collaterals (possibly from
influence of angiogenic factors, VEGF) will cause shunting of blood around liver.
22. Varices:
Hepatic venous pressure
gradient > 12 mmHg.
In esophageal varices , prefer
variceal ligation (with
multiband ligator) over
endoscopic sclerotherapy.
In gastric varices, injection
with a glue will be more
beneficial .

38. General Management
1.Oxygen support to prevent hypoxia of tissues
2.IV route - Crystaloid solution/Colloids|blood.
3. Blood transfusion:
maintain Hct at 30% in the elderly, esp. with comorbid diseases eg. CHF, CRF,
IHD,COPD)
20-25% in younger pt
25-28% in portal HTN
administration of vit k
In symptomatic thrombocytopenia (<50000 )infused platelets.
FFP transfusion should not be based solely on the patient’s abnormal INR
and/or PTT.
The decision to transfuse should be based on the patient’s clinical condition.
40. Medical Management
Proton pump inhibitors-
its use is widely adopted and is mandatory in all UGIB.
PPIs are the only drugs that can maintain a gastric pH >6 and thus
prevent fibrinolysis of clot
In patients initially treated with a bolus infusion of omeprazole/
pantaprazole 80 mg followed by a continuous infusion 8mg/hr ,and
the need for endoscopic therapy has reduced.
PPI+ Endotherapy shown the best results in terms of rebleeding,
morbidity and mortality.

• A meta-analysis has suggested that intravenous administration of
somatostatin or its long-acting form octreotide decreases the risk of
rebleeding from peptic ulcers when compared with placebo or an H2
receptor blocker.(A meta-analysis. Ann Intern Med 2010; 127:1062-71)
• The use of octerotide should be considered in pts who have persistent
bleeding even on optimal medical management.
Acute upper gastrointestinal bleeding in adults. Author. John R Saltzman,:current gastroenterology
updates 2014
44. Treatment of NSAID-Related Mucosal Injury
CLINICAL SETTING RECOMMENDATION
Active ulcer
NSAID discontinued H2 receptor antagonist or PPI
NASAID continued PPI
Prophylactic therapy Misoprostol, PPI,
H.Pylori infection Eradication if active ulcer prresent or
there is a past history of peptic ulcer
disease.
• The approach to primary prevention has included avoiding the agent, using NSAIDs
that are theoretically less injurious, and/or the use of concomitant medical therapy to
prevent NSAID-induced injury.
• Several nonselective NSAIDs that are associated with a lower likelihood of GI toxicity
include diclofenac, aceclofenac, and ibuprofen.
45. Identify bleeding source
(Pre- requisites for endoscopy):
Bloody endoscopy field
1. Naso-gastric tube(RT. esp. Wide bore) –
coffee coloured/clots/fresh blood
aspirate may categorize these pts- Low/ Intermediate/High
2. Gastric Lavage –
saline with or without H2O2
prokinetic(erythromycin, metchlopromide) agents may be used.
color and rapidity of clearing: clear fluid indicates absence of GH
and pt may be subjected for endoscopy.
3. Risk of aspiration (insure airway/ E.T tube).
46. NASOGASTRIC LAVAGE
Benefits of lavage :
Better visualization during endoscopy.
Give crude estimation of rapidity of
bleeding.
Prevent the development of porto systemic
encephalopathy in cirrhosis.
Increases PH of stomach and hence
decreases clot desolution due to gastric acid
dilution
During gastric lavage use saline and not use
large volume of to avoid water intoxication.
Gastric lavage should be done in alert and
cooperative patient to avoid broncho-
pulmonary aspiration
47. NASOGASTRIC LAVAGE
If gastric aspirate either is grossly bloody or yields coffee ground
effort should be made to lavage the stomach before proceeding
to diagnostic or therapeutic endoscopy.
The presence of bloody gastric aspirate confirms UGI Bleed.
A negative aspirate (16%) does not exclude an upper bleeding.
For Example in case of duodenal ulcer due to absence of
duodenogastric reflux aspirate is clear
48. Upper GI Endoscopy
1. Urgent vs elective endoscopy: < 12 hrs
2. Studies have not found overall advantage of early endoscopy
(<12 hrs) in terms of rebleeding, need for surgery or mortality.
3. However persistent active bleeding may recquire urgent
endotherapy.
4. Elective endoscopy: Within 24-48 hrs of bleeding.

50. UTILITY OF ENDOTHERAPY
Diagnostic & Therapeutic
Endoscopic therapy resulted in a significant improvement in: Hemostasis ,
number of units of blood transfused , no. of emergency interventions,
hospital stay & hospital costs.
In the managment of adherent clots ,endoscopic therapy show
improvement when compared with PPIs
Mortality rate is lower in group treated with endoscopic therapy + PPI as
compared to alone. .(Sung JJ, Mossner J, Barkun A, et al Aliment Pharmacol
Ther 2008; 27:666-77.
51. OPTIMIZING ENDOSCOPICVISUALIZATION
Visualization of blood within the GI tract is a challenge in
managing patients with GI bleed.
This problem can be overcome by using:
double channel or large channel endoscopes, which allow for
vigorous aspiration.
i.v erythromycin(250mg bolus) can be used as a prokinetic drug
to clear the stomach of blood, it is given 30-120 minutes prior to
endoscopy
:Acute upper gastrointestinal bleeding in adults. Author. John R
Saltzman,:current gastroenterology updates 2013
52. METHODSTO CONTROL BLEEDING
Current endoscopic modalities are:
* Injection therapies (primarily with dilute epinephrine)
* Contact thermal therapies – heater probes, mono & bipolar cautery.
* Noncontact thermal methods (argon plasma coagulation)
* Mechanical treatments- endoclips, loop/ band ligation
techniques.
* Combination of above treatment modalities
53. INJECTIONTHERAPY
* Reduce blood flow by local tamponade.
* Use of vasoconstricting agents, eg epinephrine
further reduce blood flow.
(inject 0.5- to 1.0-mL aliquots of epinephrine
(1 : 20,000) via a sclerotherapy needle into four
quadrants of the ulcer within 1 to 2 mm of the
bleeding site )
* Other agents used – sclerosants like
ethanolamine & thrombogenic agents (less
efficacious).
* injection therapy not as efficacious as other
modalities of monotherapies.
54. CONTACTTHERMALTHERAPY
Monopolar cautery – currently not in use
Bipolar cautery - Thermal modality used
most extensively.
* It has the advantage over heater probes as
it can be used perpendicularly or
tangentially.
* Bleeding vessel is compressed and then
coagulated.
* Low wattage (10-15 watts in duodenum;
15-20 in stomach) is used for a prolonged
time (8-12 second pulses) .
* End point of treatment is when involved
vessel flattens out & there is no bleeding.
55. MECHANICAL TREATMENT
- therapy of choice in obvious arterial bleeding.
* Endoscopic hemoclips are widely used.
* Has theoretical advantage over cautery of not causing further tissue
damage.
* Rebleeding rates are reduced with endoclips
COMBINATION THERAPIES
* Typically involve injection therapies with thermo coagulation technique.
* Combination therapy appears to provide durable control of bleeding than
monotherapies
56. Medical Management OfVariceal Bleeding
Vasoconstrictors
Vasopresin -0.10.5 units/minute for 4 to 12hrs(up to 48hrs) with short
acting Nitrates.
Terlipressin-2mg bolus followed by 1mg every 4-6 hrly for 3- 5 days.
Somatostatin -250ug bolus then 250ug/hr infusion
Octeotride-50ug bolus then 50ug/hr infusion for 5 days
Sleisenger and Fordtran's Gastrointestinal and Liver Disease Ninth Edition
57. Pressure techniques
Esophageal balloon
• Sengstaken blakemore tube,
• Minnesota tube
• Linton Nicholas tube
Balloon should be inflated for less than 24 hrs.
75% rebleeding rate after balloon deflation.
Most reports suggest that balloon tamponade provides initial
control of bleeding in 85% to 98% of cases.
Sleisenger and Fordtran's Gastrointestinal and Liver Disease Ninth Edition
58. variceal rebleeding recurs soon after the balloon is deflated
in 21% to 60% of patients.
The major problem with tamponade balloons is a 30% rate of
serious complications, such as aspiration pneumonia,
esophageal rupture, and airway obstruction.
Clinical studies have not shown a significant difference in
efficacy between vasopressin administration and balloon
tamponade.(Pitcher JL: Safety and effectiveness of the modified Sengstaken-Blakemore tube: A
prospective study. Gastroenterology )
59. ENDOSCOPIC SCLEROTHERAPY
Various sclerosants used are
Na. morrhuate
Ethanolamine
Polidocanol(3%)
Na tetradecyl sulphate
Tissue adhesive glue – N – Butyrl – 2 –
cyanoacrylate - prefered in fundal
varices.
Sleisenger and Fordtran's Gastrointestinal and Liver Disease Ninth Edition
60. Hemostasis can be achieved in 85% to 95% of cases, with a
rebleeding rate of 25% to 30%.
Complications include esophageal ulcers, which can bleed or
perforate, esophageal strictures, mediastinitis, pleural
effusions, aspiration pneumonia.
Band ligation is the preferred endoscopic therapy for variceal
bleeding.
Sleisenger and Fordtran's Gastrointestinal and Liver Disease Ninth Edition
61. ENDOSCOPIC BAND LIGATION
A rubber band is placed over a
varix, which subsequently
undergoes thrombosis,
sloughing, and fibrosis.
Place two bands on each
esophageal variceal column,
one distally near the
gastroesophageal junction and
another 4 to 6 cm proximally.
62. Acute hemostasis generally can be achieved in 80% to 85% of
cases, with a rebleeding rate of 25% to 30%.
Band ligation is associated with fewer local complications,
especially esophageal strictures, and requires fewer endoscopic
treatment sessions than sclerotherapy.
Sleisenger and Fordtran's Gastrointestinal and Liver Disease Ninth Edition
63. SECOND LOOK ENDOSCOPY
* Routine second-look endoscopy is not recommended for most patients with peptic
ulcer bleeding.
* Typically done 24 hours after the initial endoscopy.
* Any persistent stigmata of hemorrhage are treated.
* It is beneficial in certain circumstances, especially after injection monotherapy.
Barkun A, Bardou M, Marshall JK: Ann Intern Med 2003; 139:843-57.
64. Impact of anticoagulation on rebleeding
Anticoagulation should be stopped immediately.
The presence of mild to mod anticoagulation(INR 1.3-2.7) did not
appear to alter the outcomes of endoscopic therapy.(wolf AT,Wasan SK,saltzman JR
2004;99:1238-1246)
Patients who require an antiplatelet medication and have a history of
ulcer bleeding will have less chance of recurrent bleeding if they take
aspirin 81 mg and a PPI daily compared with clopidogrel alone.

Med 2005; 352:238-44
65. Adverse prognostic factor in UGIB
1. Age over 60
2. Shock(SBP<100mmhg), pulse >100

TIPS procedure.
Endoscopic management has no role unless an obvious focal
bleeding site is identified.
The best treatment is liver transplantation.
70. Gastric Antral Vascular Ectasia:
Endoscopic therapy with argon plasma coagulation
has been shown to be equally (80%) effective in
cirrhotic and noncirrhotic patients with GAVE.
Aorto-Enteric Fistula:
Surgical treatment is required to remove the infected graft.
Therapeutic endoscopy plays no role in the management of
bleeding from an aortoenteric fistula.
71. Obscure UGIB
Obscure Occult
UGIB
Stool OBT +, no frank
bloodloss
5-100ml/day loss
For diagnosis
1.Barium Meal follow
through
2.Enteroclysis (10-20%)
OGIB diagnosed
3.Technetium labelled
nuclear scan (70-80%)
4.Helical CT angiogram
(72%)
5.Capsule Endoscopy
(70-80%) 2 images per
sec
Diagnosis &
management
1.Angiography(40-80%)
2.Push Enteroscopy(30-
50%)
3.Intra-operative
enteroscopy(50-100%)
4.Double balloon
enteroscopy (80-90%)
Obscure Overt
UGIB
Clinically evident
persistant bleed not
identifiable after OGD
with blood loss
>100ml/day
72. Prevention
Primary Prevention: to reduce ulcer incidence
PPIs or misoprostol therapy is advised in Pts taking NSAIDs
H.Pylori eradication
Prophylactic PPI therapy in InPatients with physiologic stress
Pts with cirrhosis, non selective beta blockers & endoscopic band
ligation reduces bleeding risk (compared to placebo)
Secondary Prevention:
Reduce risk of rebleeding - IV PPI therapy in Pts with PUD with high
risk stigmata.
IV Octreotide therapy – reduces esophageal variceal rebleeding.
73. TAKE HOME MESSAGE
Early Resuscitation.
Nasogastric wash + look for GH.
High dose PPI therapy for at least 72 hrs.
Urgent Endoscopic therapy for mod to severe UGI bleeding.
74. TAKE HOME MESSAGE
Nonvariceal bleeding should be treated with either:
Combination therapy using an injection of dilute epinephrine
combined with a thermo coagulation OR
Endoclip (with or without injection therapy)
Combination therapy preferred along with medical
management.
Relook endoscopy should be preferred only for mod to severe
bleeding.
Pt should also be treated for specific cause/disease.

Notas del editor
Pt’s can present with either acute or chronic blood loss over a period of time
Inflamation—Tear--Varices
gastritis results from predisposing clinical conditions that have the potential to alter local mucosal protective barriers, such as mucus, bicarbonate, blood flow, and prostaglandin synthesis.
Examples :
Hypersecretion of acid. (Zollinger-Ellison syndrome)
Defects in gastric glycoprotein mucous. ( In critically ill patients, increased refluxed bile salts or presence uremic toxins)
Ischemia (Shock,sepsis and trauma can lead to impaired perfusion of the gut)
Long term use of NSAID’s (inhibiting cyclooxygenase, decreased mucosal prostaglandin synthesis,will lead to impaired mucosal defenses)
On endoscopy - obscure site of bleeding.
