Prolonged antibiotic treatment does not prevent intra-abdominal abscesses in perforated appendicitis

Area of Science:

• Pediatric Surgery
• Infectious Diseases
• Clinical Trials

Background:

• Children with perforated appendicitis face a significant risk of developing intra-abdominal abscesses post-surgery.
• Existing evidence does not confirm that extended antibiotic therapy reduces these postoperative abscesses.
• This study investigates the impact of different postoperative antibiotic protocols on abscess formation.

Purpose of the Study:

• To compare the incidence of intra-abdominal abscesses in children with perforated appendicitis treated with two distinct postoperative antibiotic regimens.
• To evaluate whether prolonged antibiotic use, based on serum C-reactive protein (CRP) levels, impacts postoperative abscess rates.

Main Methods:

• A retrospective review of 149 pediatric patients (<18 years) who underwent appendectomy for perforated appendicitis between 1992 and 2006.
• Comparison of two groups: Hospital A (5-day antibiotics) versus Hospital B (5-day antibiotics, extended until CRP <20 mg/l).
• Univariate logistic regression analysis was used to identify risk factors for abscess formation.

Main Results:

• Antibiotic duration differed significantly between groups (Hospital A: median 5 days; Hospital B: median 7 days; p < 0.0001).
• The incidence of postoperative intra-abdominal abscesses was similar in both groups (p = 0.95).
• Female sex was identified as a risk factor for abscess formation; surgical technique and young age were not significant factors.

Conclusions:

• Extended antibiotic treatment based on serum CRP levels does not decrease the rate of postoperative intra-abdominal abscesses in children following perforated appendicitis surgery.
• The findings suggest that current protocols for prolonged antibiotic use in this patient population may not be beneficial.
• Further research may be needed to optimize antibiotic stewardship in pediatric perforated appendicitis.
