Causes of Upper GI Bleeding
There are many causes for upper GI hemorrhage. Causes are usually anatomically divided into their location in the upper gastrointestinal tract. Patients are usually stratified into having either variceal or non-variceal sources of upper GI hemorrhage, as the two have different treatment algorithms and prognosis.
The causes for upper GI hemorrhage include the following:
- Esophageal causes:
- Esophageal varices
- Esophagitis
- Esophageal cancer
- Esophageal ulcers
- Gastric causes:
- Gastric ulcer
- Gastric cancer
- Gastritis
- Gastric varices
- Gastric antral vascular ectasia, or watermelon stomach
- Dieulafoy's lesions
- Duodenal causes:
- Duodenal ulcer
- Vascular malformations, including aorto-enteric fistulae. Fistulae are usually secondary to prior vascular surgery and usually occur at the proximal anastomosis at the third or fourth portion of the duodenum where it is retroperitoneal and near the aorta.[1][2][3]
- Hematobilia, or bleeding from the biliary tree
- Hemosuccus pancreaticus, or bleeding from the pancreatic duct

The upper part of the GI tract will usually cause black stools due to:
- Abnormal blood vessels (vascular malformation)
- A tear in the esophagus from violent vomiting (Mallory-Weiss tear)
- Bleeding stomach or duodenal ulcer
- Inflammation of the stomach lining (gastritis)
- Lack of proper blood flow to the intestines (bowel ischemia)
- Trauma or foreign body
- Widened, overgrown veins (called varices) in the esophagus and stomach
| Primary treatment option Atropine
❑ Administer a first dose 0.5 mg IV bolus ❑ Repeat every 3-5 minutes ❑ Administer a maximum dose of 3 mg | |||||||||||||||||||
| Secondary treatment options If atropine ineffective: ❑ Administer dopamine infusion (2-10 mcg/kg/min) OR ❑ Administer epinephrine infusion (2-10 mcg/min) OR ❑ Proceed with transcutaneous pacing | |||||||||||||||||||
❑ Consult a cardiologist ❑ Consider transvenous pacing | |||||||||||||||||||
