Are there reliable indicators predicting post-operative complications in acute appendicitis?

Area of Science:

• Pediatric Surgery
• Surgical Outcomes
• Appendicitis Research

Background:

• Acute appendicitis is a common surgical emergency in children.
• Post-operative complications can significantly impact patient recovery and healthcare costs.
• Identifying predictive factors for complications is crucial for optimizing surgical management.

Purpose of the Study:

• To identify key predictors of post-operative complications in pediatric acute appendicitis.
• To analyze the association between preoperative laboratory values and imaging findings with complication rates.
• To evaluate the efficacy of these predictors in both open and laparoscopic appendectomy cases.

Main Methods:

• Retrospective review of 485 pediatric acute appendicitis cases (2006-2014).
• Comparison of preoperative white blood cell (WBC) count, C-reactive protein (CRP), and appendix maximum short diameter (AMSD) between complication and non-complication groups.
• Statistical analysis including Student's T test, Fisher exact test, and multivariate analysis; p < 0.01 considered significant.

Main Results:

• Complications occurred in 6.0% of appendectomies.
• Significantly higher preoperative WBC, CRP, and AMSD were observed in the complication group (p < 0.01 for all).
• Multivariate analysis identified CRP as a significant predictor; WBC and AMSD did not reach significance in this analysis. Laparoscopic appendectomy data mirrored these findings.

Conclusions:

• Preoperative WBC, CRP, and AMSD are indicators of increased complication risk in pediatric appendicitis.
• Specific thresholds (WBC >16,500/μl, CRP >3.1 mg/dl, AMSD >11.4 mm) were associated with a sixfold increase in complications.
• These findings aid in risk stratification and management of pediatric appendicitis.
