Current Management
The goals of peptic ulcer disease management are ulcer healing and prevention of recurrence. The primary interventions used in the management of peptic ulcer disease are medical therapy and implementation of measures that address the underlying etiology of the disease.
Medical Therapy
Introduced in the late 1980s, PPIs are the cornerstone of medical therapy for peptic ulcer disease.6 These agents irreversibly inhibit the H+/K+-ATPase pump in the gastric mucosa and thereby inhibit gastric acid secretion, promoting ulcer healing. PPIs improve rates of ulcer healing compared to H2-receptor antagonists.4,7
Underlying Causes
The underlying cause of peptic ulcer disease should be addressed, in addition to initiating medical therapy. A detailed history of NSAID use should be obtained, and patients with peptic ulcers caused by NSAIDs should be counseled to avoid them, if possible. Patients with peptic ulcer disease who require long-term use of NSAIDs should be placed on long-term PPI therapy.6 Any patient with peptic ulcer disease, regardless of any history of H. pylori infection or treatment, should be tested for infection. Tests that identify active infection, such as urea breath test, stool antigen assay, or mucosal biopsy–based testing, are preferred to IgG antibody testing, although the latter is acceptable in the context of peptic ulcer disease with a high pretest probability of infection.8 Any evidence of active infection warrants appropriate treatment to allow ulcer healing and prevent recurrence.1H. pylori infection is most often treated with clarithromycin triple therapy or bismuth quadruple therapy for 14 days, with regimens selected based on the presence or absence of penicillin allergy, prior antibiotic exposure, and local clarithromycin resistance rates, when known.4,8
Managing Complications
An additional aspect of care in peptic ulcer disease is managing the complications of bleeding, perforation, and gastric outlet obstruction. Acute upper gastrointestinal bleeding (GIB) is the most common complication of peptic ulcer disease, which accounts for 40% to 60% of nonvariceal acute upper GIB.1,6 The first step in the management of acute GIB from a peptic ulcer is fluid resuscitation to ensure hemodynamic stability. If there is associated anemia with a hemoglobin level < 8 g/dL, blood transfusion should be undertaken to target a hemoglobin level > 8 g/dL. In patients with peptic ulcer disease–related acute upper GIB and comorbid cardiovascular disease, the transfusion threshold is higher, with the specific cutoff depending on clinical status, type and severity of cardiovascular disease, and degree of bleeding. Endoscopic management should generally be undertaken within 24 hours of presentation and should not be delayed in patients taking anticoagulants.9 Combination endoscopic treatment with through-the-scope clips plus thermocoagulation or sclerosant injection is recommended for acutely bleeding peptic ulcers with high-risk stigmata.
Pharmacologic management of patients with bleeding peptic ulcers with high-risk stigmata includes PPI therapy, with an 80 mg intravenous (IV) loading dose followed by continuous infusion of 8 mg/hr for 72 hours to reduce rebleeding and mortality. Following completion of IV therapy, oral PPI therapy should be continued twice daily for 14 days, followed by once-daily dosing thereafter.9Patients with peptic ulcer perforation present with sudden-onset epigastric abdominal pain and have tenderness to palpation, guarding, and rigidity on examination, often along with tachycardia and hypotension.1,4 Computed tomography (CT) of the abdomen is 98% sensitive for identifying and localizing a perforation. Most perforations occur in the duodenum or antrum.
Management of a peptic ulcer perforation requires consultation with a surgeon to determine whether a nonoperative approach may be employed (eg, a stable patient with a contained perforation), or if surgery is indicated. The surgical approach to peptic ulcer perforation has been impacted by the clinical success of gastric acid suppression with PPIs and H. pylori eradication, but a range of surgical approaches are still used to repair perforations, from omental patch repair with peritoneal drain placement, to more extensive surgeries such as wedge resection or partial gastrectomy.4 Perforation carries a high mortality risk, up to 20% to 30%, and is the leading cause of death in patients with peptic ulcer disease.1,4
Gastric outlet obstruction, a rare complication of peptic ulcer disease, results from recurrent ulcer formation and scarring. Obstruction often presents with hypovolemia and metabolic alkalosis from prolonged vomiting. CT imaging with oral contrast is often the first diagnostic test employed to demonstrate obstruction. Upper endoscopy should be performed to evaluate the appearance and degree of obstruction as well as to obtain biopsies to evaluate for a malignant etiology of the ulcer disease. Endoscopic balloon dilation has become the cornerstone of initial therapy for obstruction from peptic ulcer disease, especially in the case of ulcers due to reversible causes. Surgery is now typically reserved for cases of refractory obstruction, after repeated endoscopic balloon dilation has failed to remove the obstruction. However, because nearly all patients with gastric outlet obstruction present with malnutrition, nutritional deficiencies should be addressed prior to the patient undergoing surgical intervention. Surgical options include pyloroplasty, antrectomy, and gastrojejunostomy.4
