Brief Summary

Appendectomy for acute appendicitis has recently been questioned as being the only correct treatment for appendicitis. Appendectomy has been reported to have significant early and late morbidity. This can be avoided with antibiotic treatment alone. Moreover, better quality of life and lower costs have been associated with antibiotic treatment alone. Five clinical trials in selected patients (males, older than 18 years) comparing appendectomy and antibiotic treatment alone as primary mode of treatment found that antibiotic treatment alone is safe and effective in 48-95% of the patients Conclusive evidence with regard to the efficacy of antibiotic treatment alone in children with proven acute appendicitis however is lacking. We propose a prospective cohort study to answer the following questions:

Outcome Measures

Primary Outcomes (1)

  • Safety of initial antibiotic treatment strategy

    Occurrence of major complications, such as: A. Anaphylactic shock and other allergic reaction to antibiotics administered b. Recurrent appendicitis within 8 weeks c. Recurrent appendicitis within one year after discharge d. Development of perforated appendicitis e. Occurrence of major complaints after delayed appendectomy such as intra-abdominal abscess (IAA), stumpleakage, superficial site infection (SSI), anaesthesia related complications, secondary bowel obstruction (SBO), re-admission, need for re-intervention f. Re-admission g. Re-intervention other than delayed appendectomy

    0-12 months

Secondary Outcomes (1)

  • Safety of the direct appendectomy treatment strategy

Eligibility Criteria

Age7 Years - 17 Years

Healthy VolunteersNo
Age GroupsChild (0-17)

You may qualify if:

  • Age 7-17 years
  • Radiologically confirmed simple appendicitis, defined as:
  • a. Clinical findings: i. Unwell, but not generally ill ii. Localized tenderness in the right iliac fossa region iii. Normal/hyperactive bowel sounds iv. No guarding v. No mass palpable b. Ultrasonography: i. Incompressible appendix with an outer diameter of ≥6 mm ii. Hyperaemia within the appendiceal wall iii. Without fecalith iv. Infiltration of surrounding fat v.

  • Severe sepsis or septic shock, as defined by the international paediatric sepsis consensus conference \[39\]. See attachment 1.
  • Signs of complex appendicitis
  • Children with a fecalith on ultrasonography.
  • Patients with serious associated conditions or malformations such as:
  • Congenital or acquired cardiac or pulmonary disease with significant hemodynamic consequences
  • Immunodeficiency
  • Malignancy
  • Homozygous sickle cell disease
  • Metabolic disorders
  • Patient with documented type 1 allergy to the antibiotics used
