[Disease name] must be differentiated from other diseases that cause [clinical feature 1], [clinical feature 2], and [clinical feature 3], such as [differential dx1], [differential dx2], and [differential dx3].
The various causes responsible for UGIB include [[peptic ulcer disease]], [[esophagitis]], [[gastritis]]/gastropathy, [[Varices|esophagogastric varices]], [[Varices|ectopic varices]], portal hypertensive gastropathy, [[angiodysplasia]], dieulafoy's lesion, gastric antral vascular ectasia, [[Mallory-Weiss syndrome]] and [[Gastrointestinal tumor|upper GI tumors]] and must be differentiated from one another.

==Differentiating Upper Gastrointestinal Bleeding from other Diseases==
*[Disease name] must be differentiated from other diseases that cause [clinical feature 1], [clinical feature 2], and [clinical feature 3], such as [differential dx1], [differential dx2], and [differential dx3].
Several diseases can present with UGIB, and hence must be differentiated from one another.<ref name="pmid27653583">{{cite journal |vauthors=Graham DY |title=Upper Gastrointestinal Bleeding Due to a Peptic Ulcer |journal=N.

** '''''[[Esophagitis|HSV]]''''' – Discrete, superficial [[ulcers]], with well-demarcated borders that tend to involve the upper or mid-[[esophagus]]; vesicles may be seen
** '''''[[CMV]]''''' – Ulcers range from small and shallow to large (>1 cm) and deep; most patients have multiple lesions
** '''''[[Candida]]''''' – Diffuse white plaques

Overview

The various causes responsible for UGIB include peptic ulcer disease, esophagitis, gastritis/gastropathy, esophagogastric varices, ectopic varices, portal hypertensive gastropathy, angiodysplasia, dieulafoy's lesion, gastric antral vascular ectasia, Mallory-Weiss syndrome and upper GI tumors and must be differentiated from one another.

Differentiating Upper Gastrointestinal Bleeding from other Diseases

Several diseases can present with UGIB, and hence must be differentiated from one another.[1][2][3][4][5][6][7]

The following table summarizes the various causes of Upper gastrointestinal bleeding

Disease/Cause Bleeding manifestations Symptoms Risk factors Endoscopic findings
Hematemesis Melena Hematochezia Occult blood Abdominal
pain
Dysphagia Dyspepsia Weighloss
Ulcerative or erosive
Peptic ulcer disease + + + + + - + +/-
  • Ulcer with smooth, regular, rounded edges
  • Ulcer base often filled with exudate
  • Examination of the ulcer may reveal:
    • Active bleeding
    • Nonbleeding visible vessel
    • Adherent clot
    • Flat pigmented spot
    • Clean ulcer base
Esophagitis + + - + - + - -
  • Peptic esophagitis
    • The ulcerations are usually irregularly shaped or linear, multiple, and distal.
  • Pill-induced
  • Infectious esophagitis:
    • HSV – Discrete, superficial ulcers, with well-demarcated borders that tend to involve the upper or mid-esophagus; vesicles may be seen
    • CMV – Ulcers range from small and shallow to large (>1 cm) and deep; most patients have multiple lesions
    • Candida – Diffuse white plaques
    • HIV – Tends to involve the mid to distal esophagus, ulcers may be shallow or deep, and may be large
Gastritis/gastropathy + + - + + - + -
  • Erythematous mucosa
  • Superficial erosions
  • Nodularity
  • Diffuse oozing
Complications of portal hypertension
Esophagogastric varices + + + - + - - -
  • Vascular structures that protrude into the esophageal and/or gastric lumen
  • Findings associated with an increased risk of hemorrhage:
    • Longitudinal red streaks on the varices (red wale marks)
    • Cherry-colored spots that are flat and overlie varices
    • Raised, discrete red spots
Ectopic varices + + + - - - - -
Portal hypertensive gastropathy + + + + + - - -
  • Mosaic-like pattern that gives the gastric mucosa a "snakeskin" appearance
Vascular lesions
Angiodysplasia + + + + - - - -
  • Small (5 to 10 mm), flat, cherry-red lesions, often with a fern-like pattern of arborizing, ectatic blood vessels radiating from a central vessel.
Dieulafoy's lesion + + + - + - - -
  • Usually located in the proximal stomach
  • May have active arterial spurting from the mucosa without an associated ulcer or mass
  • If the bleeding has stopped, there may be a raised nipple or visible vessel without an associated ulcer
Gastric antral vascular ectasia + + + + + - - -
  • Longitudinal rows of flat, reddish stripes radiating from the pylorus into the antrum.
Traumatic or iatrogenic
Mallory-Weiss syndrome + + + - - - - -
  • Tear in the esophagogastric junction.
  • Usually singular and longitudinal, but may be multiple.
  • The tear may be covered by an adherent clot.
Foreign body ingestion + + + + - + - -
  • Psychiatric disorders
  • Dementia
  • Loose dentures
  • Visualization of the foreign body endoscopically.
Post-surgical anastomotic hemorrhage (marginal ulcers) + + + + + - + -
  • Ulceration/friable mucosa at an anastomotic site.
Aortoenteric fistula + + + - + - - -
  • Infectious aortitis
  • Prosthetic aortic graft
  • Atherosclerotic aortic aneurysm
  • Penetrating ulcers
  • Tumor invasion
  • Trauma
  • Radiation injury
  • Foreign body perforation
  • Endoscopy may reveal a graft, an ulcer or erosion at the site
  • Adherent clot, or an extrinsic pulsatile mass in the distal duodenum or esophagus.
Tumors
Upper GI tumors + + + + + + + +
  • Ulcerated mass in the esophagus, stomach, or duodenum.
  • In gastric malignancies:
    • The folds surrounding the ulcer crater may be nodular, clubbed, fused, or stop short of the ulcer margin
    • The margins may be overhanging, irregular, or thickened
  • Bleeding lymphoma may appear as
Miscellaneous
Hemobilia + + + - + - - - History of:
Hemosuccus pancreaticus + + + - + - + -
  • Blood or clot emanating from the ampulla.
  • Cross-sectional imaging or angiography is often required to confirm the diagnosis.
