| ==Background==
| | {{GI bleeding pages}} |
| *Bleeding originating proximal to ligament of Treitz
| |
| | |
| ==Diagnosis==
| |
| ===History===
| |
| *Hematemesis
| |
| *Coffee-ground emesis
| |
| *Melena + age <50 suggests upper GI bleed
| |
| *Vomiting + retching followed by hematemesis = Mallory-Weiss
| |
| *Aortic graft = aortoenteric fistula
| |
| *Meds
| |
| **ASA, steroids, NSAIDs, anticoagulants
| |
| *ETOH abuse
| |
| **Peptic ulcer disease, gastritis, varices
| |
| *Pseudo-melena
| |
| **Iron or bismuth use
| |
| ===Physical Exam===
| |
| *Tachycardia, hypotension
| |
| *Liver disease
| |
| **Spider angiomata, palmar erythema, jaundice, gynecomastia
| |
| *Coagulopathy
| |
| **Petechiae/purpura
| |
| *ENT exam
| |
| **Swallowed blood may result in coffee-ground emesis or melena
| |
| *Rectal exam

| #Peptic ulcer disease (most common cause)
| |
| #Gastritis/esophagitis
| |
| #Gastric/esophageal varices
| |
| #Mallory-Weiss Syndrome

| ==Workup==
| |
| #2 large bore IV
| |
| #Type and cross
| |
| #CBC & serial Hb
| |
| #Chemistry
| |
| ##BUN/Cr >30 suggests UGI if no hx of renal failure (incr absorption/digestion of hb)
| |
| #Coags (if INR > 1.5 transfuse FFP)
| |
| #LFTs
| |
| #Guaiac
| |
| #?ECG (if >50 yo or if suspicious for silent MI)
| |
| #?CXR (if suspect perforation)
| |
| #?NG lavage
| |
| ##Controversial
| |
| ###Pros
| |
| ####Positive aspirate proves strong evidence for an UGI source of bleeding
| |
| ####Can assess presence of ongoing active bleeding
| |
| ####Can prepare pt for endoscopy
| |
| ###Cons
| |
| ####Uncomfortable
| |
| ####Negative aspirate does not conclusively exclude UGI source
| |
| ####Provides useful information in only minority of pts w/o hematemesis
| |
| ####Erythromycin can provide equal endoscopy conditions as lavage
| |
| | |
| | |
| #IVF/blood
| |
| #IV PPI (Protonix 40-80mg x 1, then 8mg/hr)
| |
| #Octreotide (suspected varices: 50mcg bolus, then 25mcg/hr)
| |
| #Ceftriaxone (if e/o ascites; decreases mortality)
| |
| #?Consider vasopressin/sengstaken-blakemore tube if no access to endoscopy
| |
| | |
| If aortic graft --> immed surg consult
| |
| | |
| ===Consider===
| |
| #Proctoscopy (22cm from anal verge)

| #Sigmoidoscopy (60cm from anal verge)
