Fournier’s gangrene

Disease Description (Causes and Symptoms)

• Definition·pathophysiology: A condition in which inflammatory cells infiltrate the gastric mucosa; it may be acute or chronic. If it progresses to chronic atrophic gastritis or intestinal metaplastic gastritis, the risk of gastric cancer increases.
• Main causes: Helicobacter pylori infection, nonsteroidal anti-inflammatory drugs (NSAIDs)/aspirin, alcohol, bile reflux, severe stress (such as trauma, burns, or sepsis), and, rarely, bacterial, parasitic (e.g., Anisakis), or fungal infections, and caustic injury from strong acids or alkalis.
• Symptoms: Often asymptomatic. Indigestion, epigastric (upper abdominal) pain·burning sensation (heartburn), nausea·vomiting, postprandial bloating·early satiety, and, if bleeding occurs, black stools or hematemesis.

Treatment Methods (Standard Treatment·Medications·Procedures/Surgery·Lifestyle Management and Precautions)

• Diagnostic principles: Upper gastrointestinal endoscopy (with biopsy if necessary) is recommended for people aged 40 or older, those with alarm symptoms (persistent vomiting·difficulty swallowing·weight loss·gastrointestinal bleeding, etc.), or those who do not respond to empirical treatment. Breath tests, stool antigen tests, tissue biopsy, and other tests may be used when Helicobacter pylori needs to be identified.
• Medication treatment:
  • Helicobacter pylori positive: Eradication therapy (first-line treatment according to national·regional guidelines—PPI + amoxicillin + clarithromycin, etc., or alternative regimens). If eradication fails, retreatment is performed (considering culture·antibiotic susceptibility testing).
  • Symptom relief: Acid-suppressing medications (PPIs) are preferred; H2 blockers may be used as an alternative. Antacids·mucosal protectants (such as sucralfate) may be used as adjuncts.
  • NSAID-related: Stop or replace the causative medication; combine with a PPI if necessary.
• Procedures/Surgery: Generally unnecessary. In emergencies such as bleeding complications or perforation, endoscopic hemostasis·surgery may be required.
• Lifestyle management:
  • Stop smoking·limit alcohol, avoid long-term NSAID use (consult a doctor if necessary), temporarily limit irritating foods (spicy foods·excessive fat, etc.), and eat regular small meals.
  • During eradication treatment, take the prescribed antibiotics·PPI completely as directed.
• Precautions·side effects:
  • Be aware of antibiotic side effects (gastrointestinal disturbances, allergies) and drug interactions (e.g., clarithromycin with certain medications) during eradication therapy.
  • Consider the possibility that long-term PPI use may increase the risk of reduced bone mineral density·hypomagnesemia·gastrointestinal infections.
• Complications: Gastric ulcers, gastrointestinal bleeding, gastric mucosal atrophy·intestinal metaplasia, increased long-term risk of gastric cancer, and anemia (from chronic bleeding or absorption problems).

Outpatient Visit Checklist (Examples of Items to Bring·Tests·Information for the Medical Interview)

• Items to bring:
  • A list of currently taken medications (including prescription drugs·OTC medications·supplements)
  • Previous diagnostic certificates·endoscopy·Helicobacter pylori test results (if available)
  • Records of recent weight changes and notes on when symptoms began and how they have progressed
• Information to organize in advance of the doctor's questions:
  • Symptoms (location·severity·timing of pain, triggers·relieving factors), symptoms suggesting bleeding (black stools·hematemesis), relationship to meals, medication use (especially NSAIDs·anticoagulants), alcohol·smoking history
• Test preparation:
  • If a Helicobacter pylori test (breath·stool) or upper gastrointestinal endoscopy is needed, instructions on stopping medications (especially PPIs) vary depending on the type of test — confirmation is required before the appointment

Examples of General Questions to Ask the Doctor

• "What does my diagnosis (or Helicobacter pylori test result) mean?"
• "What treatment do you recommend, and how long is it expected to take?"
• "What are the main side effects of the prescribed medication, and which drug interactions should I be aware of?"
• "Are there any lifestyle changes I need to make immediately?"
• "When will follow-up tests (such as a breath test·endoscopy) be needed after treatment?"

Examples of Disease-Specific Questions

• "After Helicobacter pylori eradication treatment, which test will be used to confirm whether eradication was successful, and when will it be performed?"
• "Atrophic gastritis (or metaplastic gastritis) was seen on my endoscopy. How often should I undergo endoscopy to prevent gastric cancer?"
