What is the recommended treatment for an adult with an umbilical infection?

Treatment of Umbilical Infection in Adults

For adult umbilical infections, the recommended treatment includes surgical drainage of any abscess combined with appropriate antibiotic therapy targeting common skin and soft tissue pathogens. 1

Diagnostic Approach

• Umbilical infections in adults present with erythema, edema, tenderness, and purulent discharge from the umbilicus 1
• Imaging studies should be performed to identify underlying causes:
  • Ultrasound and CT scan of the abdomen and pelvis are recommended to identify possible urachal remnants or other embryological structures that may be infected 1, 2
  • These imaging studies help determine the extent of infection and guide surgical management 2

Treatment Algorithm

Initial Management

• Cleanse the umbilical area with an antiseptic solution 3
• Avoid using tincture of iodine as it may cause tissue irritation; other iodine-containing products (e.g., povidone-iodine) can be used instead 3
• Do not apply topical antibiotic ointments or creams to the umbilical area as they may promote fungal infections and antimicrobial resistance 3

Antibiotic Therapy

• For uncomplicated infections, oral antibiotics with gram-positive and anaerobic coverage are recommended:
  • Ciprofloxacin 500 mg orally twice daily for 7-14 days is an appropriate option 4
  • For complicated intra-abdominal infections, ciprofloxacin should be used in conjunction with metronidazole 4
• For severe infections with systemic symptoms:
  • Initial intravenous antibiotics may be necessary before transitioning to oral therapy 4
  • Treatment should continue for at least 2 days after signs and symptoms of infection have disappeared 4

Surgical Management

• Incision and drainage is indicated for any abscess formation 1
• If imaging reveals an underlying urachal remnant or other embryological structure:
  • Complete surgical resection of the infected structure is recommended to prevent recurrence 1, 2
  • Partial treatments that do not address the underlying cause often lead to recurrent infections 2

Special Considerations

• Recurrent umbilical infections in adults should raise suspicion for:

  • Infected remnants of the allantois or omphalomesenteric (vitelline) duct 2
  • Urachal abnormalities 1, 5
  • Local factors such as poor hygiene, obesity, or foreign bodies 2

• For patients with renal impairment requiring antibiotic therapy, dosage adjustments are necessary:

  • For creatinine clearance 30-50 mL/min: ciprofloxacin 250-500 mg every 12 hours
  • For creatinine clearance 5-29 mL/min: ciprofloxacin 250-500 mg every 18 hours 4

Follow-up

• Monitor for resolution of infection and potential complications 2
• Consider follow-up imaging to ensure complete resolution of any underlying abnormalities 2
• For recurrent cases despite appropriate treatment, more extensive surgical exploration may be necessary 2

Common Pitfalls

• Failure to identify and address underlying anatomical abnormalities is the most common cause of recurrent umbilical infections in adults 2
• Treating only with antibiotics without surgical drainage when an abscess is present often leads to treatment failure 1
• Inadequate duration of antibiotic therapy may result in incomplete resolution and recurrence 4
