Management of Ulcer Bleeding: ACG
Guidelines
Initial Assessment and Risk Stratification
• Hemodynamic status should be assessed immediately upon presentation
and resuscitative measures begun as needed (Strong recommendation).
• Blood transfusions should target Hgb ≥ 7 g / dl, with higher Hgbs targeted in
patients with clinical evidence of intravascular volume depletion or
comorbidities, such as coronary artery disease (Conditional
recommendation).
• Risk assessment should be performed to stratify patients into higher and
lower risk categories and may assist in initial decisions such as timing of
endoscopy, time of discharge, and level of care (Conditional
recommendation).
• Discharge from the ED without inpatient endoscopy may be considered in
patients with urea nitrogen < 18.2 mg / dl; Hgb ≥ 13.0 g / dl for men (12.0 g /
dl for women), systolic blood pressure ≥ 110 mm Hg; pulse < 100 beats /
min; and absence of melena, syncope, cardiac failure, and liver disease, as
they have < 1 % chance of requiring intervention (Conditional
recommendation).
Laine & Jensen Am J Gastroenterol 2012; 107:345–360
Management of Ulcer Bleeding: ACG Guidelines
Pre-endoscopic interventions
• Intravenous infusion of erythromycin (250 mg ~ 30 min before
endoscopy) should be considered to improve diagnostic yield and
decrease the need for repeat endoscopy. However, erythromycin
has not consistently been shown to improve clinical outcomes
(Conditional recommendation).
• Pre-endoscopic intravenous PPI (e.g., 80 mg bolus followed by 8 mg
/ h infusion) may be considered to decrease the proportion of
patients who have higher risk stigmata of hemorrhage at endoscopy
and who receive endoscopic therapy. However, PPIs do not improve
clinical outcomes such as further bleeding, surgery, or death
(Conditional recommendation).
• If endoscopy will be delayed or cannot be performed, intravenous
PPI is recommended to reduce further bleeding (Conditional
recommendation).
• Nasogastric or orogastric lavage is not required in patients with
UGIB for diagnosis, prognosis, visualization, or therapeutic effect
(Conditional recommendation).
Laine & Jensen Am J Gastroenterol 2012; 107:345–360
Management of Ulcer Bleeding: ACG Guidelines
Timing of endoscopy
• Patients with UGIB should generally undergo endoscopy
within 24 h of admission, following resuscitative efforts to
optimize hemodynamic parameters and other medical
problems (Conditional recommendation).
• In patients who are hemodynamically stable and without
serious comorbidities endoscopy should be performed as
soon as possible in a non-emergent setting to identify the
substantial proportion of patients with low-risk endoscopic
findings who can be safely discharged (Conditional
recommendation).
• In patients with higher risk clinical features (e.g., tachycardia,
hypotension, bloody emesis or nasogastric aspirate in
hospital) endoscopy within 12 h may be considered to
potentially improve clinical outcomes (Conditional
recommendation).
Laine & Jensen Am J Gastroenterol 2012; 107:345–360
Management of Ulcer Bleeding: ACG Guidelines
- Endoscopy
• Stigmata of recent hemorrhage should be recorded as they predict risk
of further bleeding and guide management decisions. The stigmata, in
descending risk of further bleeding, are active spurting, non-bleeding
visible vessel, active oozing, adherent clot, fl at pigmented spot, and
clean base (Strong recommendation).
• Endoscopic therapy should be provided to patients with active spurting
or oozing bleeding or a non-bleeding visible vessel (Strong
recommendation).
• Endoscopic therapy may be considered for patients with an adherent
clot resistant to vigorous irrigation. Benefi t may be greater in patients
with clinical features potentially associated with a higher risk of
rebleeding (e.g., older age, concurrent illness, inpatient at time bleeding
began) (Conditional recommendation).
• Endoscopic therapy should not be provided to patients who have an
ulcer with a clean base or a fl at pigmented spot (Strong
recommendation).
Laine & Jensen Am J Gastroenterol 2012; 107:345–360
Management of Ulcer Bleeding: ACG Guidelines
- Endoscopy
• Epinephrine therapy should not be used alone. If used, it should be
combined with a second modality (Strong recommendation).
• Thermal therapy with bipolar electrocoagulation or heater probe and
injection of sclerosant (e.g., absolute alcohol) are recommended
because they reduce further bleeding, need for surgery, and mortality
(Strong recommendation).
• Clips are recommended because they appear to decrease further
bleeding and need for surgery. However, comparisons of clips vs. other
therapies yield variable results and currently used clips have not been
well studied (Conditional recommendation).
• For the subset of patients with actively bleeding ulcers, thermal therapy
or epinephrine plus a second modality may be preferred over clips or
sclerosant alone to achieve initial hemostasis (Conditional
recommendation).
Laine & Jensen Am J Gastroenterol 2012; 107:345–360
Management of Ulcer Bleeding: ACG
Guidelines - Therapy after initial endoscopy
• After successful endoscopic hemostasis, intravenous PPI therapy with 80 mg
bolus followed by 8 mg/h continuous infusion for 72 h should be given to
patients who have an ulcer with active bleeding, a non-bleeding visible vessel,
or an adherent clot (Strong recommendation).
• Patients with ulcers that have flat pigmented spots or clean bases can receive
standard PPI therapy (e.g., oral PPI once daily) (Strong recommendation).
• Routine second-look endoscopy, in which repeat endoscopy is performed 24 h
after initial endoscopic hemostatic therapy, is not recommended (Conditional
recommendation).
• Repeat endoscopy should be performed in patients with clinical evidence of
recurrent bleeding and hemostatic therapy should be applied in those with
higher risk stigmata of hemorrhage (Strong recommendation).
• If further bleeding occurs after a second endoscopic therapeutic session,
surgery or interventional radiology with transcathether arterial embolization is
generally employed (Conditional recommendation).
Laine & Jensen Am J Gastroenterol 2012; 107:345–360
International Consensus on Nonvariceal
Upper Gastrointestinal Bleeding:
Postdischarge ASA and NSAIDs
• In patients with previous ulcer bleeding who require
an NSAID, it should be recognized that treatment
with a traditional NSAID plus PPI or a COX-2 inhibitor
alone is still associated with a clinically important risk
for recurrent ulcer bleeding.
• In patients with previous ulcer bleeding who require
an NSAID, the combination of a PPI and a COX-2
inhibitor is recommended to reduce the risk for
recurrent bleeding from that of COX-2 inhibitors
alone.
Barkun AN, et al. Ann Intern Med. 2010;152:101-113.
International Consensus on Nonvariceal
Upper Gastrointestinal Bleeding:
Postdischarge ASA and NSAIDs
• In patients who receive low-dose ASA and develop
acute ulcer bleeding, ASA therapy should be
restarted as soon as the risk for cardiovascular
complication is thought to outweigh the risk for
bleeding.
• In patients with previous ulcer bleeding who require
cardiovascular prophylaxis, it should be recognized
that clopidogrel alone has a higher risk for rebleeding
than ASA combined with a PPI.

  • 33. Management of Ulcer Bleeding: ACG Guidelines Initial Assessment and Risk Stratification • Hemodynamic status should be assessed immediately upon presentation and resuscitative measures begun as needed (Strong recommendation). • Blood transfusions should target Hgb ≥ 7 g / dl, with higher Hgbs targeted in patients with clinical evidence of intravascular volume depletion or comorbidities, such as coronary artery disease (Conditional recommendation). • Risk assessment should be performed to stratify patients into higher and lower risk categories and may assist in initial decisions such as timing of endoscopy, time of discharge, and level of care (Conditional recommendation). • Discharge from the ED without inpatient endoscopy may be considered in patients with urea nitrogen < 18.2 mg / dl; Hgb ≥ 13.0 g / dl for men (12.0 g / dl for women), systolic blood pressure ≥ 110 mm Hg; pulse < 100 beats / min; and absence of melena, syncope, cardiac failure, and liver disease, as they have < 1 % chance of requiring intervention (Conditional recommendation). Laine & Jensen Am J Gastroenterol 2012; 107:345–360
  • 34. Management of Ulcer Bleeding: ACG Guidelines Pre-endoscopic interventions • Intravenous infusion of erythromycin (250 mg ~ 30 min before endoscopy) should be considered to improve diagnostic yield and decrease the need for repeat endoscopy. However, erythromycin has not consistently been shown to improve clinical outcomes (Conditional recommendation). • Pre-endoscopic intravenous PPI (e.g., 80 mg bolus followed by 8 mg / h infusion) may be considered to decrease the proportion of patients who have higher risk stigmata of hemorrhage at endoscopy and who receive endoscopic therapy. However, PPIs do not improve clinical outcomes such as further bleeding, surgery, or death (Conditional recommendation). • If endoscopy will be delayed or cannot be performed, intravenous PPI is recommended to reduce further bleeding (Conditional recommendation). • Nasogastric or orogastric lavage is not required in patients with UGIB for diagnosis, prognosis, visualization, or therapeutic effect (Conditional recommendation). Laine & Jensen Am J Gastroenterol 2012; 107:345–360
  • 35. Management of Ulcer Bleeding: ACG Guidelines Timing of endoscopy • Patients with UGIB should generally undergo endoscopy within 24 h of admission, following resuscitative efforts to optimize hemodynamic parameters and other medical problems (Conditional recommendation). • In patients who are hemodynamically stable and without serious comorbidities endoscopy should be performed as soon as possible in a non-emergent setting to identify the substantial proportion of patients with low-risk endoscopic findings who can be safely discharged (Conditional recommendation). • In patients with higher risk clinical features (e.g., tachycardia, hypotension, bloody emesis or nasogastric aspirate in hospital) endoscopy within 12 h may be considered to potentially improve clinical outcomes (Conditional recommendation). Laine & Jensen Am J Gastroenterol 2012; 107:345–360
  • 36. Management of Ulcer Bleeding: ACG Guidelines - Endoscopy • Stigmata of recent hemorrhage should be recorded as they predict risk of further bleeding and guide management decisions. The stigmata, in descending risk of further bleeding, are active spurting, non-bleeding visible vessel, active oozing, adherent clot, fl at pigmented spot, and clean base (Strong recommendation). • Endoscopic therapy should be provided to patients with active spurting or oozing bleeding or a non-bleeding visible vessel (Strong recommendation). • Endoscopic therapy may be considered for patients with an adherent clot resistant to vigorous irrigation. Benefi t may be greater in patients with clinical features potentially associated with a higher risk of rebleeding (e.g., older age, concurrent illness, inpatient at time bleeding began) (Conditional recommendation). • Endoscopic therapy should not be provided to patients who have an ulcer with a clean base or a fl at pigmented spot (Strong recommendation). Laine & Jensen Am J Gastroenterol 2012; 107:345–360
  • 37. Management of Ulcer Bleeding: ACG Guidelines - Endoscopy • Epinephrine therapy should not be used alone. If used, it should be combined with a second modality (Strong recommendation). • Thermal therapy with bipolar electrocoagulation or heater probe and injection of sclerosant (e.g., absolute alcohol) are recommended because they reduce further bleeding, need for surgery, and mortality (Strong recommendation). • Clips are recommended because they appear to decrease further bleeding and need for surgery. However, comparisons of clips vs. other therapies yield variable results and currently used clips have not been well studied (Conditional recommendation). • For the subset of patients with actively bleeding ulcers, thermal therapy or epinephrine plus a second modality may be preferred over clips or sclerosant alone to achieve initial hemostasis (Conditional recommendation). Laine & Jensen Am J Gastroenterol 2012; 107:345–360
  • 38. Management of Ulcer Bleeding: ACG Guidelines - Therapy after initial endoscopy • After successful endoscopic hemostasis, intravenous PPI therapy with 80 mg bolus followed by 8 mg/h continuous infusion for 72 h should be given to patients who have an ulcer with active bleeding, a non-bleeding visible vessel, or an adherent clot (Strong recommendation). • Patients with ulcers that have flat pigmented spots or clean bases can receive standard PPI therapy (e.g., oral PPI once daily) (Strong recommendation). • Routine second-look endoscopy, in which repeat endoscopy is performed 24 h after initial endoscopic hemostatic therapy, is not recommended (Conditional recommendation). • Repeat endoscopy should be performed in patients with clinical evidence of recurrent bleeding and hemostatic therapy should be applied in those with higher risk stigmata of hemorrhage (Strong recommendation). • If further bleeding occurs after a second endoscopic therapeutic session, surgery or interventional radiology with transcathether arterial embolization is generally employed (Conditional recommendation). Laine & Jensen Am J Gastroenterol 2012; 107:345–360
  • 39. International Consensus on Nonvariceal Upper Gastrointestinal Bleeding: Postdischarge ASA and NSAIDs • In patients with previous ulcer bleeding who require an NSAID, it should be recognized that treatment with a traditional NSAID plus PPI or a COX-2 inhibitor alone is still associated with a clinically important risk for recurrent ulcer bleeding. • In patients with previous ulcer bleeding who require an NSAID, the combination of a PPI and a COX-2 inhibitor is recommended to reduce the risk for recurrent bleeding from that of COX-2 inhibitors alone. Barkun AN, et al. Ann Intern Med. 2010;152:101-113.
  • 40. International Consensus on Nonvariceal Upper Gastrointestinal Bleeding: Postdischarge ASA and NSAIDs • In patients who receive low-dose ASA and develop acute ulcer bleeding, ASA therapy should be restarted as soon as the risk for cardiovascular complication is thought to outweigh the risk for bleeding. • In patients with previous ulcer bleeding who require cardiovascular prophylaxis, it should be recognized that clopidogrel alone has a higher risk for rebleeding than ASA combined with a PPI. Barkun AN, et al. Ann Intern Med. 2010;152:101-113.
