Overview

Peptic ulcer disease must be differentiated from other causes of acute upper gastrointestinal bleeding such as esophageal varices, Mallory-Weiss syndrome, gastrointestinal cancer, arteriovenous malformations, esophagitis, and esophageal ulcer. Peptic ulcer disease must also be differentiated from gastroesophageal reflux disease (GERD), irritable bowel syndrome, pancreatitis, and Zollinger-Ellison Syndrome.

Differentiating Peptic Ulcer from other Diseases

  • Acute upper gastrointestinal bleeding: PUD accounts for the majority of acute episodes of gastrointestinal bleeding[1] (up to 40%)[2], but there are other causes:[3]
    • Esophageal varices: history of cirrhosis (and portal hypertension)
    • Mallory-Weiss syndrome: history of repeated vomiting
    • Gastrointestinal cancer: history of anorexia or weight loss, tobacco smoking and alcohol drinking.
    • Arteriovenous malformations: Painless bleeding in >70 years old patients, history of iron deficiency anemia.
    • Esophagitis or esophageal ulcer: heartburn, indigestion, or dysphagia
    • Dieulafoy ulcer: painless bleeding
  • Alpha-1 Antitrypsin Deficiency AATD: besides lung disease, liver disease (hepatitis, cirrhosis, and hepatoma) represents another clinical manifestation of AATD,[4][5] therefore those patients can present upper gastrointestinal bleeding and abdominal pain, in the context of altered liver function.[6]
  • Cirrhosis:[7][8] chronic liver disease is often asymptomatic until complications occur, such as variceal bleeding, ascites, primary peritonitis, sepsis or hepatic encephalopathy.
  • Gastroesophageal reflux disease (GERD):[9][10][11][12] current definition is "a condition which develops when the reflux of stomach contents causes troublesome symptoms and/or complications.” Heartburn and regurgitation are the cardinal symptoms of GERD, but patients can often present dysphagia and chest pain. Less common symptoms include odynophagia, sialorrhea, subxiphoid pain or nausea. Also, patients can present extraesophageal GERD-related syndromes, such as chronic cough, laryngitis, asthma or erosion of dental enamel.
  • Irritable bowel syndrome
  • Pancreatitis
  • Zollinger-Ellison Syndrome

Duodenal ulcer

  • Pain aggravates with empty stomach

Gastric ulcer

  • Pain aggravates with food
  • Pain alleviates with food
- - - Gastric ulcers
  • Discrete mucosal lesions with a punched-out smooth ulcer base with whitish fibrinoid base
  • Most ulcers are at the junction of fundus and antrum
  • 0.5-2.5cm

Duodenal ulcers

Other diagnostic tests
Gastrinoma - -

(suspect gastric outlet obstruction)

- - - Useful in collecting the tissue for biopsy

Diagnostic tests

Gastric Adenocarcinoma - - Esophagogastroduodenoscopy
  • Multiple biopsies are taken to establish the diagnosis
