Peptic Ulcer Disease Flashcards
PUD
Break in mucosa and submucosa lining; defined as ulcerations or erosion in the stomach and duodenum due to the corrosive action of gastric fluid
HCl and pepsin in acidic solution plays a role in mucosal breaks regardless of the provoking cause (H. pylori, aspirin, or NSAIDs)
Major (chronic) forms:
1. DUODENAL (80%) – exacerbations occur, necessitating surgery in 5-10% cases
- GASTRIC (20%) – less curvature of the stomach, near the pylorus
Protective vs. hostile factors
PROTECTIVE FACTORS:
- Prostaglandins
- Bicarb
- Blood flow
- Mucous production
HOSTILE FACTORS:
- H. pylori and smoking (most common)
- Gastric acid
- NSAIDs
Risk factors
PUD risk factors:
1. H. pylori (toxin released by this bacteria promotes inflammation and ulceration) – pt is predisposed to gastric CA; Transmission: Fecal or water-to-oral (inversely proportional to socioeconomic status)
- NSAIDs (H. pylori is present in 22-63% of pts taking NSAIDs) – Inhibits prostaglandin = Increased gastric acid and pepsin and decreased bicarb. and mucous production
- Excessive smoking – inhibits prostaglandin, bicarb., blood flow, and gastric emptying
- Acid hypersecretion syndrome (Zollinger Ellison syndrome)
- Genetic (20-50%)
Clinical manifestations
Duodenal ulcer:
- Pain improved with food or antacids
- Burning epigastric pain
- Pain aggravated by fasting
Gastric ulcer:
- Pain triggered or worsened by eating (shortly after meals)
- Not relieved by antacids
**Acute pain may be a sign of a complication (perforation) or it may be another disease entity (pancreatitis, GB disease, CAD)
Diagnosis
R/o other priority issues (EKG, LFTs, amylase, abdominal ultrasound; gallstones, CPK)
XRAY – r/o free air (perforation)
Upper endoscopy – biopsy (CA, cytology, H. pylori)
Labs – CBC, FOBT
Urease breath test – presence of H. pylori
Fasting serum gastrin – r/o Zollinger’s
Medical management
Goals:
- Pain relief
- Ulcer healing
- Prevention of ulcer recurrence
- Reduction of complication
Medications:
- H2 receptor antagonist (Ranitidine)
- PPI (Omeprazole)
- Sucralfate – binds to ulcer tissue; acts as a barrier
Diet:
- Avoid dietary irritants (caffeine, ETOH, spices)
- Small meals (~6)
- Avoid smoking
Surgery – only performed for non-healing or bleeding ulcers
Monitor for complications:
- GI hemorrhage – abdominal pain, changes in VS, decreased H&H, hematemesis, blood in stool
- Intestinal infarction or perforation – abdominal pain, changes in VS, increased WBC
- Rule out other issues – i.e. CV (EKG)
Additional: Abdominal assessment, VS, monitor gastric pH, pain, labs (electrolytes, BUN, CBC), weight, and collaboration (dietary, pharmacy, pt resources)
Pt education
Teaching:
1. Avoid eating 2 hrs. before bedtime – eating increases gastric secretion
- Diet (small meals) – avoid NSAIDs, spicy foods, ETOH, smoking
- Know when to contact PCP – hematemesis, unusual abdominal pain, blood in stool
- Meds.
