Differentials

Common

Peptic ulcer disease (PUD)

History

history of NSAID use (often with concomitant use of corticosteroids) or past ulcers is common; ingestion of food often transiently improves abdominal pain; coffee-ground emesis and hematemesis are very common; hematochezia (bright red blood from the rectum) is rare, and is usually associated with extremely brisk UGIB and significant hemodynamic compromise

Exam

midepigastric tenderness to palpation

1st investigation
  • esophagogastroduodenoscopy (EGD):

    direct visualization of the ulcer

    More
  • Helicobacter pylori urea breath test or stool antigen test:

    positive for H pylori

    More
Other investigations
  • barium radiography:

    barium within an ulcer crater

    More
  • fasting serum gastrin level:

    hypergastrinemia in Zollinger-Ellison syndrome

    More

Esophageal varices

History

any history of intravenous drug use that could lead to chronic hepatitis, chronic alcoholism, or cirrhosis should immediately arouse suspicions of portal hypertension and thus varices; variceal bleeds often lead to brisk hematemesis

Exam

stigmata of chronic liver disease are often present (e.g., jaundice, hepatomegaly, splenomegaly, ascites)

1st investigation
  • esophagogastroduodenoscopy:

    direct visualization of the varices

    More
Other investigations
  • CT scan/portal angiography:

    can show collateral veins and recanalized umbilical vein

Esophagitis

History

often seen in the context of GERD; sometimes associated with dysphagia or odynophagia; history may include chronic heartburn; patients may mention a globus sensation; hoarseness can also be present; many patients who present with melena and who are suspected of peptic ulcer disease will be found to have esophagitis on endoscopy

Exam

reproducible pain can be demonstrated on swallowing

1st investigation
  • esophagogastroduodenoscopy:

    direct visualization of esophageal irritation/inflammation

Other investigations

    Mallory-Weiss tear

    History

    classically, patients note hematemesis following retching or vomiting, but any increase in intraesophageal pressure (e.g., from seizures, hiccups, or straining) can cause a tear; some tears develop spontaneously; alcohol use, advanced age, and presence of hiatal hernias are common underlying features

    Exam

    bleeding is sometimes accompanied by midepigastric or retrosternal pain

    1st investigation
    • esophagogastroduodenoscopy:

      direct visualization of intramural dissections

      More
    Other investigations

      Uncommon

      Boerhaave syndrome (spontaneous esophageal perforation)

      History

      classically, patients note retching or vomiting followed by severe retrosternal pain and/or epigastric pain; history of alcohol intake is common; other common symptoms and signs include dyspnea, tachypnea, cyanosis, sepsis, and shock

      Exam

      important to look for subcutaneous emphysema, which may be absent in some patients

      1st investigation
      • chest x-ray:

        may reveal free mediastinal, peritoneal, or prevertebral air; pleural effusion with or without pneumothorax, widened mediastinum, and subcutaneous emphysema may be seen in late presentations

        More
      Other investigations
      • pleural fluid amylase measurement:

        indicative of esophageal rupture

      • water-soluble contrast swallow study (Gastrografin):

        helpful for localizing the lesion

      • CT scan:

        may be used as a confirmatory test; findings include esophageal wall edema, peri-esophageal fluid with or without bubbles, and widened mediastinum

      Gastric varices

      History

      any history of intravenous drug use that could lead to chronic hepatitis, chronic alcoholism, or cirrhosis should immediately arouse suspicions of portal hypertension and thus varices; strongly associated with massive bleeding and rapid hemodynamic compromise

      Exam

      stigmata of chronic liver disease are often present (e.g., jaundice, hepatomegaly, splenomegaly, ascites)

      1st investigation
      • esophagogastroduodenoscopy:

        classically, varices are seen in cardia of stomach

        More
      Other investigations
      • CT scan/portal angiography:

        collateral veins and recanalized umbilical vein

      Arteriovenous malformations (AVMs)

      History

      usually painless and, as such, are often asymptomatic until they cause overt bleeding; associated with cirrhosis, end-stage renal disease, advanced age, and von Willebrand disease

      Exam

      often present with a nonfocal physical exam due to their frequently painless nature; patients can have chronic bleeding of which they are unaware

      1st investigation
      • esophagogastroduodenoscopy:

        direct visualization of centrifugally expanding dilated capillaries

        More
      Other investigations
      • CT angiography:

        accumulation of vessels in the intestinal wall, early-filling vein, or enlarged supplying artery

        More

      Dieulafoy lesions

      History

      often present painlessly; lesions are submucosal vessels that dive toward the gastric lumen and, through erosion, rupture and produce rapid blood loss; regarded as congenital arterial dysplasias but are most often symptomatic in men with alcohol histories, cardiovascular disease including hypertension, diabetes, or chronic kidney disease

      Exam

      often present with a nonfocal physical exam; the bleeding can be intermittent

      1st investigation
      • esophagogastroduodenoscopy (EGD):

        direct visualization of lesion

        More
      Other investigations
      • endoscopic ultrasound:

        identification of lesion

        More

      Upper GI tumors

      History

      constitutional symptoms such as involuntary weight loss or night sweats

      Exam

      cachectic patient, sometimes with a palpable abdominal mass

      1st investigation
      • esophagogastroduodenoscopy and biopsy:

        direct visualization of mass and positive histology

        More
      Other investigations
      • endoscopic ultrasound:

        presence of upper GI malignancies

        More
      • PET/CT scan:

        noninvasive, indirect visualization of mass

        More

      Aortoenteric fistulae (AEF)

      History

      often present with a "herald bleed" (an episode of self-limited bleeding before a massive bleed that can result in exsanguination), either in the form of hematochezia or of hematemesis; can also present with significant abdominal or back pain and fever; history of a vascular graft or aortic aneurysm should markedly heighten clinical suspicion

      Exam

      septic shock can occur; abdominal bruits or pulsatile masses can infrequently be detected

      1st investigation
      • esophagogastroduodenoscopy:

        direct visualization of fistula

        More
      Other investigations
      • abdominal CT, aortography, abdominal ultrasound:

        contiguity of aorta with bowel

        More

      Coagulopathy

      History

      history may include liver disease, anticoagulant medication, genetic abnormalities of clotting (e.g., hemophilia, von Willebrand disease)

      Exam

      may be signs of underlying liver disease (e.g., jaundice, hepatomegaly, splenomegaly, ascites)

      1st investigation
      • clotting profile:

        abnormal prothrombin time: prolonged INR

      Other investigations
