Abstract

Background With effective antibiotics against enteric flora and computed tomography-guided drainage for abscesses, the initial use of nonoperative therapy for children with appendicitis has increased both in recent reports and at our hospital. However, it has been reported that these patients have a relatively longer hospital stay and that their treatment is more expensive than those who undergo aggressive surgical intervention. Methods This was a retrospective cohort study based in a single medical center. A systemic chart review was conducted to identify risk factors for prolonged hospitalization in pediatric appendicitis patients not initially undergoing surgical treatment. Patient demographics, clinical symptoms, duration of symptoms, laboratory findings, imaging findings, complications, and length of hospital stay were analyzed. Logistic regression analysis was used to identify significant predictors of prolonged hospitalization (≥15 days) and readmission. Results One hundred and twenty-five patients were recruited in this study, of whom 53 (42.4%) had prolonged hospitalization. The values of serum C-reactive protein (CRP) were significantly higher in patients with prolonged hospitalization compared with those without prolonged hospitalization (203 ± 108.6 mg/L vs. 140 ± 93.0 mg/L, p = 0.001). Risk factors of prolonged hospitalization were serum CRP >150 mg/L (35/53 vs. 28/72, p = 0.001), abscess formation (38/53 vs. 35/72, p = 0.008), and multiple abscesses (10/53 vs. 1/72, p = 0.001). Under multivariate analysis, CRP >150 mg/L (odds ratio = 1.004, p = 0.0334) and multiple abscesses (odds ratio = 8.788, p = 0.044) were two independent predictors for prolonged hospitalization. Conclusion Marked elevation of serum CRP (>150 mg/L) and multiple abscesses are two independent risk factors for prolonged hospitalization in children with appendicitis who are initially treated nonoperatively.
