Brief Summary

When the appendix becomes infected and inflamed, it is called appendicitis. Sometimes, if the infection and inflammation get worse, the appendix can die or burst, leading to a larger infection or even pus pockets around the appendix. This is called complicated, or perforated, appendicitis. Three common treatments for complicated appendicitis are

  • appendectomy (removal of the appendix) right away
  • appendectomy several weeks after the diagnosis
  • treating the appendicitis without performing an appendectomy This study seeks to determine which of these three approaches is most cost-effective in children with complicated appendicitis.

Outcome Measures

Primary Outcomes (1)

  • Overall Cost of Care

    Total health care cost starting from time of admission was the intention of this outcome measure. However, the institutions potentially involved were unwilling to provide access to any cost data so this could not be analyzed for any length of time.

    The original intention was to gather cost data for 2 years per person following admission. As no cost data was able to be procured, there is no time frame to which it applies.

Secondary Outcomes (8)

  • Complications

    During index/initial hospitalization (generally not more than 5-6 weeks)

  • Parents Away From Work

    During index/initial hospitalization (generally not more than 5-6 weeks)

  • Duration of Antibiotic Therapy

    During index/initial hospitalization (generally not more than 5-6 weeks)

  • Length of Stay

    During index/initial hospitalization (generally not more than 5-6 weeks)

  • Number of Percutaneous Drainage Procedures

    During index/initial hospitalization (generally not more than 5-6 weeks)

  • +3 more secondary outcomes

Study Arms (3)

Early Appendectomy

Procedure: Early AppendectomyDrug: Antibiotics

Interval Appendectomy

EXPERIMENTAL
Procedure: Interval AppendectomyDrug: Antibiotics

No Appendectomy

EXPERIMENTAL
Drug: Antibiotics

Interventions

Removal of the appendix within 24 hours of admission

Early Appendectomy

Removal of the appendix after initial antibiotic treatment and at least 6 weeks of recovery.

Interval Appendectomy

Zosyn will be administered unless the patient has a penicillin allergy, in which case patients will receive both ciprofloxacin and metronidazole.

Also known as: Zosyn (piperacillin/tazobactam); ciprofloxacin; metronidazole
