Peptic Ulcer Disease

Peptic ulcer disease is a common mucosal breach driven primarily by H. pylori infection and NSAID use. Diagnosis relies on upper endoscopy with biopsy for H. pylori; all gastric ulcers require biopsy to exclude malignancy. Eradication of H. pylori is the cornerstone of definitive management, reducing recurrence from >80% to <5%. Acute bleeding requires a four-pillar approach: resuscitation, pre-endoscopic high-dose IV PPI, urgent endoscopy with hemostasis for high-risk stigmata (Forrest Ia-IIb), and 72-hour post-endoscopic IV PPI followed by oral PPI. Glasgow-Blatchford score guides triage; Forrest classification predicts rebleeding risk. Routine second-look endoscopy is not beneficial. Successful eradication should be confirmed with urea breath test or stool antigen. Long-term PPI maintenance is indicated for idiopathic PUD, patients requiring continued NSAID/aspirin therapy, and those with refractory complications. Prevention strategies include H. pylori screening in high-prevalence areas, NSAID avoidance, and PPI coprescription with anti-thrombotic agents. Special populations (elderly, cirrhotic, ESRD, pediatric) require tailored approaches with aggressive risk management.

Peptic ulcer disease (PUD) is a breach in the gastric or duodenal mucosa extending through the muscularis mucosae, with a lifetime prevalence of 5-10% and annual incidence of 0.1-0.3%. The two dominant etiologies, Helicobacter pylori infection and NSAID use, drive a final common pathway of mucosal injury. Complications (bleeding, perforation, obstruction) occur in 10-20% of patients and account for most morbidity and mortality. Diagnosis hinges on upper endoscopy with biopsy for H. pylori, and management has been transformed by eradication therapy: successful cure reduces ulcer recurrence from >80% to <5%. Acute bleeding requires a four-pillar approach: resuscitation, pre-endoscopic PPI, endoscopic hemostasis for high-risk stigmata, and post-endoscopic high-dose IV PPI for 72 hours.

Overview and Recommendations

Background

  • •Peptic ulcer disease (PUD) is a mucosal defect in the stomach or duodenum that penetrates the muscularis mucosae. It affects 5-10% of the population during their lifetime, with an annual incidence of 0.1-0.3%. The disease is classified by location as gastric ulcer (GU) or duodenal ulcer (DU), DU is almost universally associated with , while GU has a more heterogeneous etiology including NSAIDs and mandates biopsy to exclude .
  • •Two dominant pathogenic drivers, H. pylori infection and NSAID use, account for the majority of cases. H. pylori colonizes the gastric mucus layer and employs virulence factors (GGT, heat shock proteins) that damage epithelium and subvert host defenses. NSAIDs injure mucosa both systemically (COX-1 inhibition reducing cytoprotective prostaglandins) and topically (uncoupling oxidative phosphorylation). The relative contribution of H. pylori is estimated at 57% globally, corresponding to 3.5 million potentially preventable cases annually.
  • •The host immune response determines clinical outcome: patients who develop ulceration have a 2.4-fold reduced regulatory T-cell response compared to those with asymptomatic colonization, unleashing unchecked Th1/Th2-mediated inflammation. This immune deficit explains why only a minority of H. pylori-colonized individuals progress to ulcer disease.
  • •Temporal trends show declining hospitalization rates across OECD countries (average annual percent change -3.8% for incidence, -4.4% for mortality), driven by H. pylori eradication and PPI use. However, increasing use of low-dose aspirin and NSAIDs in an aging population partially offsets this decline. The 2022 UK audit reports overall in-hospital mortality for PUD bleeding at 8.8%, down from 10% in 2007.
  • •Key variants include H. pylori-associated (decreasing in the West), NSAID-induced (often silent until bleeding), idiopathic (up to 25% of series, increasing proportion), and complicated PUD (bleeding, perforation, obstruction). The Forrest classification stratifies bleeding ulcers endoscopically into six categories (Ia-III) that predict rebleeding risk and guide hemostatic therapy.

Evaluation

  • •Suspect PUD in any patient with epigastric pain (burning or gnawing), dyspepsia, or alarm features (dysphagia, weight loss, GI bleeding, anemia). Duodenal ulcers typically cause pain 2-3 hours after meals and at night, relieved by food; gastric ulcers often worsen with eating. However, up to one-third of ulcers, especially in older adults and NSAID users, are asymptomatic until a complication occurs.
  • •Ask about NSAID/aspirin use (including over-the-counter), H. pylori exposure history, smoking, alcohol, and prior ulcer disease. Document use of anticoagulants ( , ) and antiplatelet agents, as these increase bleeding risk and influence management.
  • •Examine for epigastric tenderness, but recognize its limited sensitivity/specificity. Actively seek signs of complicated disease: pallor, tachycardia, orthostatic hypotension, melena on digital rectal exam, coffee-ground emesis (bleeding); gastric distension and succussion splash (obstruction); peritoneal signs with rigidity and rebound (perforation).
  • •Order (EGD) as the gold-standard diagnostic test. It provides direct visualization of the ulcer, assessment of stigmata of recent hemorrhage using the Forrest classification (Ia: spurting, Ib: oozing, IIa: visible vessel, IIb: adherent clot, IIc: flat spot, III: clean base), and opportunity for biopsy and hemostatic therapy.
  • •In every patient with PUD, test for H. pylori at the time of endoscopy using biopsy-based rapid urease test or histology. If endoscopy is not performed or biopsies are omitted, use noninvasive testing: stool antigen test or . Serology is not recommended for initial diagnosis in active bleeding. Alarmingly, 19% of hospitalized patients with bleeding PUD are not tested within 60 days, failure to test is associated with 51% higher risk of rebleeding or death at 1 year.
  • •All gastric ulcers must undergo biopsy to exclude malignancy; duodenal ulcers rarely require biopsy unless atypical (e.g., post-bulbar, multiple, or refractory).
  • •If perforation is suspected, obtain upright chest radiograph or abdominal CT to detect free air. Point-of-care ultrasound has moderate sensitivity (66%) and high specificity (85%) for pneumoperitoneum.
  • •Laboratory studies include (anemia), BUN-to-creatinine ratio >30 suggests upper GI bleed, coagulation studies, liver enzymes, and type and crossmatch if active bleeding. Stool antigen for H. pylori is preferred if biopsies were not taken.
  • •Risk stratify using validated scores: the (GBS) at presentation predicts need for intervention, GBS = 0 identifies very-low-risk patients suitable for outpatient management. The (full, after endoscopy) predicts mortality; Rockall ≥5 defines high-risk group for prophylactic transarterial embolization.
  • •Also consider differential diagnoses: non-ulcer dyspepsia, gastroesophageal reflux disease, gastritis, gastric cancer, pancreatitis, biliary colic, and Zollinger-Ellison syndrome (suspect with multiple ulcers, atypical location, diarrhea, hypergastrinemia).

Management

  • •For acute bleeding PUD, initiate resuscitation immediately: secure airway if hematemesis or altered mental status, obtain large-bore IV access, and give crystalloids. Use a restrictive transfusion strategy (target Hb >70 g/L in most patients; >80-90 g/L with significant comorbidities or ongoing bleeding).
  • •Administer high-dose intravenous PPI as soon as ulcer bleeding is suspected (e.g., 80 mg bolus followed by 8 mg/hour continuous infusion, or 80 mg bolus then 8 mg/hour). This reduces the need for endoscopic therapy and downstages bleeding stigmata.
  • •Perform urgent EGD within 24 hours of presentation for hemodynamically stable patients with overt bleeding. For high-risk stigmata (Forrest Ia, Ib, IIa, IIb), deliver endoscopic hemostasis using combination therapy: injection of dilute epinephrine (1:10,000) plus thermal coagulation or hemoclip placement. For adherent clots (IIb), endoscopic therapy reduces rebleeding risk (RR 0.40).
  • •After successful hemostasis, continue high-dose IV PPI for 72 hours (e.g., esomeprazole 8 mg/hour or pantoprazole 8 mg/hour). Then transition to oral PPI once daily (e.g., omeprazole 20 mg, pantoprazole 40 mg) for at least 8 weeks.
  • •Do not perform routine second-look endoscopy: a meta-analysis of 9 RCTs showed no significant benefit in rebleeding, surgery, or mortality compared with single endoscopic hemostasis.
  • •For H. pylori-positive PUD, eradicate the infection. First-line therapy in areas with <15% clarithromycin resistance: triple therapy with PPI (e.g., omeprazole 20 mg BID or lansoprazole 30 mg BID) + clarithromycin 500 mg BID + amoxicillin 1 g BID (or metronidazole 500 mg BID if penicillin-allergic) for 14 days. In settings with high clarithromycin resistance, use bismuth quadruple therapy: PPI + bismuth subsalicylate 262 mg QID + metronidazole 250 mg QID + tetracycline 500 mg QID for 10-14 days. Concomitant therapy (PPI + amoxicillin + clarithromycin + metronidazole for 10 days) is an alternative.
  • •Confirm H. pylori eradication ≥4 weeks after completing therapy using urea breath test or stool antigen test; the patient must be off PPIs and antibiotics for at least 2 weeks before testing. Without confirmation, persistent infection, the most common cause of recurrent ulcer, goes undetected.
  • •Discontinue NSAIDs if possible. If NSAID therapy is required (e.g., for cardiovascular prevention with aspirin), coprescribe a PPI (e.g., 20 mg daily with aspirin 100 mg daily). In patients with aspirin-related ulcers, continuing aspirin with a PPI is as effective as switching to (healing rate >86% at 12 weeks).
  • •For idiopathic PUD (H. pylori-negative, NSAID-negative), initiate maintenance PPI therapy indefinitely (e.g., omeprazole 20 mg daily). Consider testing for with fasting gastrin level and gastric acid analysis.
  • •Avoid NSAIDs, aspirin (unless necessary for cardiovascular protection), and non-dihydropyridine CCBs (diltiazem, verapamil) as they may exacerbate symptoms or increase bleeding risk. Use acetaminophen for analgesia.
  • •When to refer: to surgery or interventional radiology if endoscopic hemostasis fails (persistent bleeding, perforation). For benign , refer for endoscopic balloon dilation (EBD) as initial intervention (clinical success 78-92%). Graham patch repair for perforation (laparoscopic preferred).
  • •Discharge criteria: hemodynamic stability, no clinical evidence of rebleeding, tolerating oral intake, and risk stratification suitable for outpatient management (GBS = 0). Arrange H. pylori eradication therapy and confirmatory testing in 4 weeks. Schedule follow-up endoscopy for gastric ulcers to confirm healing and exclude malignancy.
  • •For patients on anti-thrombotic therapy, resume anticoagulants and antiplatelets as soon as hemostasis is secure (usually 1-7 days post-bleed), guided by thrombotic vs. bleeding risk. Coprescribe PPI indefinitely during anti-thrombotic therapy.
  • •In elderly patients, be vigilant for PPI overuse: deprescribe when no definitive indication (e.g., healed ulcer after eradication with no ongoing NSAID/aspirin use). Median PPI overuse duration is 346 days beyond the approved 8-week course.
  • •For pediatric PUD, use weight-based PPI, amoxicillin, and clarithromycin; bismuth quadruple therapy in older children. Check antibiotic susceptibility due to high primary clarithromycin resistance (20%). Surgery required in 87% of perforated cases.

Board Review — High Yield

  • •Forrest classification, Stratifies bleeding ulcer stigmata from Ia (spurting) to III (clean base); high-risk (Ia-IIb) require endoscopic hemostasis; rebleeding risk <5% for clean base.
  • •Glasgow-Blatchford score = 0, Identifies patients who can be safely discharged without endoscopy; predicts <1% risk of needing intervention.
  • •H. pylori eradication, Reduces ulcer recurrence from >80% to <5%; confirm cure with urea breath test ≥4 weeks after therapy off PPI/antibiotics.
  • •Delay in H. pylori eradication, Each additional day beyond 7 days from diagnosis increases hazard of recurrent ulcer (HR 1.17 at 8-30 days, HR 3.55 at >1 year).
  • •All gastric ulcers must be biopsied, To exclude gastric adenocarcinoma; duodenal ulcers rarely require biopsy unless atypical.
  • •NSAID/aspirin + PPI, In patients requiring anti-thrombotic therapy and with prior PUD, coprescribe PPI to prevent rebleeding; continuing aspirin with PPI is non-inferior to switching to clopidogrel.
  • •Cirrhosis + PUD bleeding, 90-day mortality 25.3% vs 18.3% without liver disease; triples adjusted mortality rate.
  • •Endoscopic hemostasis for adherent clots, Reduces rebleeding by 60% (RR 0.40) compared to medical management alone.
  • •Second-look endoscopy not recommended, No significant reduction in rebleeding, need for surgery, or mortality vs. single definitive hemostasis (meta-analysis, 9 RCTs).
  • •Potassium-competitive acid blockers (P-CABs), Faster, more consistent acid suppression but not first-line due to cost and limited long-term safety data; reserved for PPI-refractory cases or resistance-adapted regimens.
