Paediatric acute mesenteric lymphadenitis usually improves significantly with abdominal pain after fasting, intravenous fluids, antibiotics and symptomatic treatment, and no surgery is required.
If there is no improvement after the above regimen, or if the condition is urgent and acute appendicitis, intussusception or intestinal obstruction is also suspected, the surgeon will need to perform surgical exploration and, if necessary, simultaneous surgical treatment.
