Introduction
Bleeding from the gastrointestinal (GI) tract may be considered upper or lower GI hemorrhage (bleeding proximal or distal to the jejunum).
Etiology
- causes of obscure GI bleed
- proximal to the ligament of Trietz
- small bowel
- angioectasia (angiodysplasia)*
- Peutz-Jeghers syndrome
- Meckel diverticulum
- young adult, acute GI bleed otherwise asymptomatic, normal upper GI endoscopy
- hemangioma
- small intestinal malignancy
- hereditary hemorrhagic telangiectasia
- colon
- risk factors for nosocomial gastrointestinal bleeding
- age > 60 years
- male sex
- acute renal failure
- liver disease
- sepsis
- prophylactic anticoagulation
- combination of anticoagulants & antiplatelet agents[9]
- coagulopathy
- treatment on the medical service
* most common cause of obscure GI bleed[2]
Clinical manifestations
- postural hypotension suggests moderate bleeding (10-20% of circulating volume)
- supine hypotension suggests severe bleeding (> 20% of circulating volume)
- hematemesis suggests upper GI bleed
- melena suggests bleeding proximal to the cecum
- bright red blood per rectum suggests an anorectal or left colon bleed
- maroon-colored stool suggests a right colon or distal cecum bleed
Laboratory
- type & screen (cross-match if transfusion is indicated)
- complete blood count (CBC)
- hemoglobin & hematocrit are poor indicators of acute blood loss
- platelets
- PT/aPTT
- serum chemistries
Diagnostic procedures
- upper GI endoscopy &/or lower GI endoscopy
- capsule endoscopy[19]
- repeat GI endoscopy with biopsies recommended prior to capsule endoscopy[2]
- not so according[16][19]
- double ballon enteroscopy only for treating identified lesions[16]
- push enteroscopy is third line
- offers opportunity for therapeutic intevention[2]
- electrocardiogram in elderly patients
Radiology
- technetium labeled nuclear scan (scintigraphy) provides the best sensitivity for actively bleeding lesion not detected by upper GI endoscopy &/or lower GI endoscopy or capsule endoscopy[2]
Complications
risk factors for increased morbidity & mortality
- age > 60 years
- more than 1 comorbidity
- severe blood loss (> 5 units)
- hemodynamic instability
- bright red hematemesis with hypotension
- multisystem failure
- variceal bleeding
- peptic ulceration (> 2 cm)
- recurrent hemorrhage (within 72 hours)
- emergency surgery
- weekend hemorrhage[11]
- lack of endoscopy services on the weekend may be linked an increase in mortality in patients with non-variceal upper gastrointestinal hemorrhage[11]
Management
- assessment & restoration of hemodynamic stability
- two large bore intravenous (IV) catheters (14-18 gauge), central venous catheter adds no additional benefit
- normal saline or lactated ringers to restore volume
- urine output is best measure of adequate fluid replacement
- hetastarch 5% (Hespan) until blood products available
- transfusion therapy
- packed red blood cells (RBC) to maintain hematocrit> 25% or > 30% in patients with cardiopulmonary disease
- correct coagulopathy with fresh frozen plasma (FFP)
- thrombocytopenia (platelets < 40,000/mm3) should be corrected with platelet transfusions or with therapy directed at the cause of the thrombocytopenia
- platelet transfusion not indicated for GI bleed associated with antiplatelet therapy[10]
- increased mortality, no reduction of risk for rebleed
- platelet transfusion not indicated for GI bleed associated with antiplatelet therapy[10]
- massive transfusion (> 6 units)
- blood warming
- monitor for hypocalcemia from citrate in blood products
- nasogastric tube placement
- aspiration of gastric contents to confirm upper GI bleed
- gastric lavage with normal saline
- coffee ground-like material, strong + occult blood
- false negatives with: intermittent bleeding, duodenal bleed without reflux to stomach
- use of iced saline or norepinephrine of no value
- gastric lavage increases likelihood of early endoscopy but not better patient outcomes[3]
- digital rectal examination or anoscopy: masses, hemorrhoids, gross or occult blood, melena
- specific measures to control bleeding
- specific measures for comorbidities
- restarting anti-platelet therapy &/or anticoagulation within 7 days is reasonable (benefits seem to outweigh risks) [14[
