Treatment of Mesenteric Adenitis

Mesenteric adenitis treatment primarily consists of supportive care with hydration and pain management, with antibiotics reserved only for cases with evidence of infection or abscess formation. 1

Initial Management

  • Supportive care is the cornerstone of treatment for uncomplicated mesenteric adenitis, focusing on:

    • Adequate hydration with intravenous fluids 1
    • Pain control with appropriate analgesics 1
    • Rest until symptoms resolve 1
  • Most cases of primary mesenteric adenitis are self-limited and resolve with symptomatic treatment alone 2

Antibiotic Therapy

  • Antibiotics should NOT be routinely administered for all cases of mesenteric adenitis 3, 1

  • Antimicrobial therapy is indicated only when there is evidence of:

    • Superinfection 3
    • Intra-abdominal abscess 3, 1
    • Specific bacterial etiology requiring treatment (e.g., tuberculosis, typhoid fever) 4
  • When antibiotics are indicated, therapy should target:

    • Gram-negative aerobic and facultative bacilli
    • Gram-positive streptococci
    • Obligate anaerobic bacilli 3, 1
  • Recommended antibiotic regimens include:

    • Fluoroquinolones (e.g., ciprofloxacin) or third-generation cephalosporins combined with metronidazole 3, 1
    • Duration depends on clinical response and laboratory parameters such as CRP levels 3

Management of Complications

Abscess Management

  • For small abscesses (<3 cm) without evidence of fistula and no steroid therapy, antibiotic therapy alone may be sufficient 1

  • Larger abscesses require:

    • Percutaneous drainage (guided by ultrasound or CT) combined with antibiotics 1
    • Clinical improvement should be observed within 3-5 days after starting antibiotics and drainage 3, 1
    • If no improvement occurs, re-evaluation with repeat imaging is necessary 3, 1
    • Failure of percutaneous drainage may necessitate surgical intervention 3, 1

Special Considerations

  • Etiologic agents vary by region and may influence treatment approach:

    • In Western countries, Yersinia species are common causes 5, 4
    • In some Asian countries, non-typhoidal Salmonella, tuberculosis, and typhoid fever are significant causes 4
    • Salmonella enterica serovar Enteritidis carries potential risk for serious systemic complications and may require specific treatment 5
  • For cases with specific identified pathogens:

    • Tuberculosis requires anti-tuberculosis therapy 4
    • Typhoid fever requires appropriate antibiotic treatment 4
    • Most other infectious causes typically resolve spontaneously without antibiotics 4
  • A multidisciplinary approach involving gastroenterologists and surgeons is beneficial for complex cases 3, 1

  • Thromboprophylaxis with low molecular weight heparin should be considered in hospitalized patients to prevent complications such as portal vein thrombosis 3, 6

Follow-up

  • Follow-up imaging (typically ultrasound) is recommended to confirm resolution of adenopathy 5

  • Patients with ongoing symptoms beyond expected resolution time should undergo further diagnostic evaluation to rule out other conditions 3
