Gastric and duodenal ulcers usually cannot be differentiated based on history alone, although some findings may be suggestive (see Diagnosis). Epigastric pain is the most common symptom of both gastric and duodenal ulcers. It is characterized by a gnawing or burning sensation and occurs after meals—classically, shortly after meals with gastric ulcer and 2-3 hours afterward with duodenal ulcer.
In uncomplicated peptic ulcer disease (PUD), the clinical findings are few and nonspecific. “Alarm features" that warrant prompt gastroenterology referral[1] include bleeding, anemia, early satiety, unexplained weight loss, progressive dysphagia or odynophagia, recurrent vomiting, and family history of GI cancer. Patients with perforated PUD usually present with a sudden onset of severe, sharp abdominal pain. (See Clinical Presentation.)
In most patients with uncomplicated PUD, routine laboratory tests usually are not helpful; instead, documentation of PUD depends on radiographic and endoscopic confirmation. Testing for H pylori infection is essential in all patients with peptic ulcers. Rapid urease tests are considered the endoscopic diagnostic test of choice. Of the noninvasive tests, fecal antigen testing is more accurate than antibody testing and is less expensive than urea breath tests. A fasting serum gastrin level should be obtained in certain cases to screen for Zollinger-Ellison syndrome. (See Workup.)
Upper GI endoscopy is the preferred diagnostic test in the evaluation of patients with suspected PUD. Endoscopy provides an opportunity to visualize the ulcer, to determine the presence and degree of active bleeding, and to attempt hemostasis by direct measures, if required. Perform endoscopy early in patients older than 45-50 years and in patients with associated so-called alarm features.
Most patients with PUD are treated successfully with cure of H pylori infection and/or avoidance of nonsteroidal anti-inflammatory drugs (NSAIDs), along with the appropriate use of antisecretory therapy. In the United States, the recommended primary therapy for H pylori infection is proton pump inhibitor (PPI)–based triple therapy.[1] These regimens result in a cure of infection and ulcer healing in approximately 85-90% of cases.[2] Ulcers can recur in the absence of successful H pylori eradication. (See Treatment and Management.)
In patients with NSAID-associated peptic ulcers, discontinuation of NSAIDs is paramount, if it is clinically feasible. For patients who must continue with their NSAIDs, proton pump inhibitor (PPI) maintenance is recommended to prevent recurrences even after eradication of H pylori.[3, 4] Prophylactic regimens that have been shown to dramatically reduce the risk of NSAID-induced gastric and duodenal ulcers include the use of a prostaglandin analog or a PPI. Maintenance therapy with antisecretory medications (eg, H2 blockers, PPIs) for 1 year is indicated in high-risk patients. (See Medication.)
The indications for urgent surgery include failure to achieve hemostasis endoscopically, recurrent bleeding despite endoscopic attempts at achieving hemostasis (many advocate surgery after 2 failed endoscopic attempts), and perforation.
Patients with gastric ulcers are also at risk of developing
