Study Notes on Peptic Ulcer Disease (PUD)

Peptic Ulcer Disease (PUD)

Definition and Overview

  • Peptic Ulcer Disease (PUD)

    • PUD is a condition where the gastrointestinal (GI) mucosa is eroded by gastric acid or pepsin.

    • Typically found in the gastric (stomach) and duodenal (small intestine) regions, indicating its classification as an upper GI issue.

Epidemiology

  • Most common in women aged 50 to 60 years.

  • Increased cancer risk associated with PUD due to cellular damage.

  • Older adults (34 to 45 years old) have pain occurring 2 to 5 hours after meals, with no increased cancer risk.

Characteristics of Gastric vs. Duodenal Ulcers

  • Gastric Ulcers:

    • Located higher in the GI tract.

    • Pain occurs 1 to 2 hours after eating.

  • Duodenal Ulcers:

    • Located lower in the GI tract.

    • Pain occurs 2 to 5 hours after eating due to slower transit time.

Classification of Ulcers

  • Acute Peptic Ulcers:

    • Characterized by minimal inflammation and short duration.

  • Chronic Peptic Ulcers:

    • Can erode through the muscular wall, leading to fibrous scarring and long-term complications.

Etiology

  • Primary Causes:

    • Helicobacter pylori (H. pylori) infection: Transmitted through fecal-oral or oral-oral routes (e.g., via contaminated foods or close contact).

    • Non-Steroidal Anti-Inflammatory Drugs (NSAIDs): Major cause of gastric ulcers unrelated to H. pylori

    • Corticosteroids: May contribute to ulcer formation by affecting mucosa and decreasing protective factors.

Contributing Lifestyle Factors

  • Smoking:

    • All types, particularly cigarettes, are high-risk.

  • Diet:

    • Poor dietary choices, excessive caffeine (including decaffeinated coffee), and alcohol intake can exacerbate PUD.

  • Stress:

    • Physiological stressors can heighten gastric secretions.

Comorbid Conditions

  • Conditions that may exacerbate PUD include:

    • Chronic Obstructive Pulmonary Disease (COPD)

    • Cirrhosis

    • Pancreatitis

    • Hyperparathyroidism

    • Chronic Kidney Disease (CKD)

    • Various chronic syndromes affecting the GI tract.

Clinical Presentation

  • Varied symptoms depending on ulcer location:

    • Gastric presents with pain 1-2 hours post-meal in the epigastric area.

    • Duodenal presents with pain 2-5 hours post-meal, often lower in the epigastric region.

  • Symptoms can mimic Gastroesophageal Reflux Disease (GERD), such as:

    • Burning sensation (heartburn)

    • Cramping (may be more common in duodenal ulcers)

    • Additional symptoms may include bloating, nausea, vomiting, and fullness.

  • Diagnostic Procedures:

    • Upper GI Endoscopy and Biopsy (EGD): Primary method for diagnosis, allowing for ulcer sample collection to test for H. pylori presence and assess for cancer.

    • Gastrin Levels: Elevated gastrin may indicate increased acid production.

    • Complete Blood Count (CBC): Tests for anemia or infection.

Drug Therapy

  • Treatment Goals:

    • Reduce gastric secretions, prevent further damage, and eradicate H. pylori.

  • Triple therapy for H. pylori:

    • 14-day regimen including:

    • Two different antibiotics to combat resistance.

    • Proton Pump Inhibitors (PPIs) or H2 receptor antagonists to suppress acid production and promote healing.

    • Off-label treatments:

    • Misoprostol: Synthetic prostaglandin with protective effects on mucosa.

    • Gabapentin: Used for pain management in certain cases.

    • Sucralfate: A mucosal protectant to defend against further ulceration.

Complications of PUD

  1. Gastrointestinal Bleeding

    • Manifested as:

      • Black tarry stools (melena)

      • Bright red blood in vomit (hematemesis)

    • Severity can lead to hypovolemic shock if significant.

  2. Perforation

    • Formation of a hole in the ulcerative area.

    • Results in sudden, severe abdominal pain, rigid abdomen, and potential peritonitis.

    • Immediate medical intervention needed due to risk of abdominal infection.

  3. Gastric Outlet Obstruction

    • Caused by scarring and fibrous tissue.

    • Patients experience fullness, pain, and difficulty digesting food, often vomiting undigested food.

Treatment for Complications

  • For GI Bleeding:

    • IV fluids, potential blood transfusions for significant blood loss, and monitoring in ICU if severe.

    • Endoscopic interventions (e.g., cauterization, banding) to stop bleeding.

  • For Perforation:

    • Surgical intervention to repair perforation and prevent peritonitis.

    • Monitor for signs of infection or shock and provide supportive care.

  • For Gastric Outlet Obstruction:

    • NG tube placement to decompress the stomach.

    • Possible interventions like balloon dilation or stenting to alleviate the obstruction.

Postoperative Nursing Considerations

  • Pain management, monitoring for complications (e.g., infections, bleeding), ensuring bowel rest, and establishing NG tube patency if applicable.

  • Dietary education focusing on what to avoid post-GI surgery: spicy foods, alcohol, and NSAIDs.

  • Keeping patients informed about symptoms of concern and adequate hydration.

Miscellaneous Notes

  • Dumping Syndrome:

    • Post-gastric surgery condition where food moves quickly from the stomach to the small intestine, leading to various symptoms, including dizziness and gastrointestinal distress.

  • Gastritis:

    • Inflammation of the gastric mucosa, which can be acute or chronic, often leading to ulcer formation if untreated.

  • Upper GI Bleeds:

    • Can result from NSAID usage, varices, or tears in the esophagus from repeated vomiting.
