What is the immediate treatment approach for a patient with severe abdominal pain suspected to be due to a stomach or duodenal ulcer, with a history of chronic alcohol use, in the emergency room (ER)?

Emergency Room Treatment of Suspected Bleeding Peptic Ulcer in a Patient with Chronic Alcohol Use

Immediately initiate aggressive fluid resuscitation, start intravenous proton pump inhibitor therapy (pantoprazole 40 mg IV), administer broad-spectrum antibiotics, and arrange urgent upper endoscopy for hemostasis—this is the cornerstone of ER management for suspected bleeding peptic ulcer. 1, 2

Immediate Resuscitation and Stabilization

• Begin aggressive fluid resuscitation immediately to enhance visceral perfusion and correct hemodynamic instability, using crystalloid solutions through large-bore IV access 1
• Correct electrolyte abnormalities and obtain baseline laboratory studies including complete blood count, metabolic panel, and arterial blood gas to assess severity and guide resuscitation 3
• Insert nasogastric tube for gastric decompression and to assess ongoing bleeding 1
• Type and crossmatch blood products; transfuse packed red blood cells as needed to maintain hemodynamic stability 1

Pharmacologic Therapy

• Start intravenous pantoprazole 40 mg immediately upon presentation, as proton pump inhibitors control most bleeds when combined with endoscopic therapy 2, 4
• Administer broad-spectrum antibiotics immediately, particularly given the patient's chronic alcohol use and risk of complications 1
• Do NOT give empirical H. pylori eradication therapy in the acute setting; instead, perform H. pylori testing on all patients with bleeding peptic ulcer and initiate eradication only after confirmation 1

Urgent Endoscopy Decision-Making

• Arrange urgent upper endoscopy for all patients with suspected bleeding peptic ulcer as this is both diagnostic and therapeutic, allowing direct visualization and hemostatic intervention 1
• Endoscopic therapy controls most bleeds and should be the first-line intervention for hemostasis 1, 4
• Document ulcer size, location, and bleeding characteristics during endoscopy, as these factors predict treatment failure 1

Risk Stratification for Surgical Intervention

Critical decision point: Patients with hypotension/hemodynamic instability OR ulcers ≥2 cm at first endoscopy should proceed directly to surgical intervention without repeated endoscopy 1

• For hemodynamically stable patients with ulcers <2 cm, repeated endoscopy is appropriate if initial endoscopic hemostasis fails 1
• Immediate surgery is indicated for unstable patients with bleeding refractory to endoscopy, as mortality increases with delayed intervention 1
• Open surgery is preferred over laparoscopy for refractory bleeding peptic ulcer 1

Surgical Approach When Indicated

• Bleeding gastric ulcers should be resected or at least biopsied to rule out malignancy 1
• For bleeding duodenal ulcers (typically large posterior lesions with gastroduodenal artery involvement), perform duodenotomy with triple-loop suturing of the bleeding vessel 1
• Consider intraoperative endoscopy to facilitate localization of the bleeding site 1
• Vagotomy/drainage procedures are associated with lower mortality than simple ulcer oversew for intractable bleeding 1

Special Considerations for Chronic Alcohol Use

• Be vigilant for mesenteric ischemia in this population, as heavy alcohol consumption can cause vasoconstriction and bowel ischemia, which may complicate the clinical picture 5
• Chronic alcohol use increases the likelihood of symptomatic peptic ulcer disease and active-stage ulcers 6
• Consider damage control surgery for patients with hemorrhagic shock and severe physiological derangement to quickly resolve bleeding and allow prompt ICU admission 1

Common Pitfalls to Avoid

• Do not delay endoscopy in hemodynamically unstable patients or those with high-risk features (hypotension, ulcer ≥2 cm), as these patients may require immediate surgical intervention 1
• Do not rely on symptom response alone to exclude gastric malignancy; gastric ulcers require biopsy or resection 1
• Do not forget to test for H. pylori in all bleeding peptic ulcer patients, as eradication significantly reduces rebleeding rates (from 26% to much lower rates) 1
• Avoid stopping proton pump inhibitors, antibiotics, or bismuth products less than 2 weeks before H. pylori testing to prevent false-negative results 3
