From the Research
Mesenteric adenitis is a self-limiting condition that can be effectively managed with supportive care, including pain management and hydration, without the need for specific interventions, as evidenced by a recent study published in 2021 1.
Key Considerations
- The condition commonly affects children and adolescents, presenting with symptoms such as right lower quadrant abdominal pain, fever, and sometimes nausea, vomiting, or diarrhea.
- Treatment is primarily focused on pain management with acetaminophen (10-15 mg/kg every 4-6 hours) or ibuprofen (5-10 mg/kg every 6-8 hours) and adequate hydration.
- Rest is also recommended until symptoms improve, with the condition typically resolving within 1-4 weeks without specific interventions.
- Mesenteric adenitis is usually caused by viral infections, though bacterial infections can occasionally be responsible, and if suspected, antibiotics may be prescribed.
Diagnostic Approach
- The diagnosis is often made through ultrasound or CT scan after ruling out appendicitis, with a study published in 2017 highlighting the importance of clinical and laboratory findings in differentiating mesenteric lymphadenitis from acute appendicitis 2.
- Key differentiating factors include longer duration of symptoms, multiple ED presentations, and lower WBC and CRP levels in patients with mesenteric lymphadenitis.
Management and Outcome
- Supportive care, including pain management and hydration, is the primary approach to managing mesenteric adenitis, with a favorable outcome expected in most cases, as reported in a study published in 2021 1.
- Patients should seek medical attention if symptoms worsen, as rare complications can include abscess formation or intestinal obstruction.
- A study published in 2017 emphasized the importance of reassuring patients and families about the condition, stating that affected patients recover completely without residuals within 2-4 weeks 3.
