Image-guided abscess drainage in children with perforated appendicitis - can it wait?

Area of Science:

• Pediatric Surgery
• Interventional Radiology
• Gastroenterology

Background:

• Image-guided drainage is standard for perforated appendicitis with intra-abdominal abscesses.
• Optimal timing for intervention in pediatric cases remains unclear, lacking sufficient data.

Purpose of the Study:

• To evaluate the association between the time from diagnosis to drainage (delta time) and clinical outcomes in children with complicated appendicitis.
• To identify if delayed intervention impacts length of stay, catheter dwell time, or need for further procedures.

Main Methods:

• Retrospective study of 80 pediatric patients undergoing image-guided abscess drainage for perforated appendicitis.
• Analysis of delta time, abscess volume, and number of collections using gamma and logistic regression models.
• Outcomes assessed included length of stay, catheter dwell time, need for tissue plasminogen activator (t-PA), and additional interventions.

Main Results:

• Mean delta time was 1.5 days; no significant association was found between delta time and length of stay, catheter dwell time, need for t-PA, or additional interventions (P > 0.05).
• However, abscess volume and number of collections were significantly associated with longer length of stay, longer catheter dwell time, and increased need for additional interventions (P < 0.05).

Conclusions:

• The time interval between diagnosing an appendicitis-associated abscess and performing image-guided drainage does not appear to significantly affect key clinical outcomes in pediatric patients.
• Factors such as abscess volume and multiplicity are more critical predictors of clinical outcomes than the delay in intervention.
