Abstract


Purpose: Perforation of choledochal cyst (CC) is a relatively rare clinical presentation in pediatric populations and difficult to predict preoperatively. We assess the clinical implications by comparing clinical parameters based on a single-center experience between perforated and nonperforated CC to facilitate the appropriate management for future interventions.

Methods: A total of 92 cases of CC in pediatric patients (aged <18 years) who received surgical management between January 2003 and December 2018 at a Pusan National University Children's Hospital were reviewed. After screening the clinical features of perforated cases, we compared the demographic findings, clinical characteristics, and some laboratory results between the perforated and nonperforated groups.

Results: Perforated CC was identified in 8 patients (8.7%), and nonperforated CC in 84 patients (91.3%). Perforation can be classified into three categories: free perforation of cyst (3 cases), pinpoint perforation of cyst (2 cases), and necrotic change of cyst (3 cases). CC perforation occurred significantly more commonly in patients aged <24 months. Clinically, the perforated group showed significantly higher frequency of fever and higher C-reactive protein (CRP) level during the initial visit.

Conclusion: Perforation is more likely to be suspected in patients aged <24 months presenting together with fever and high CRP level in the initial visit. It is also necessary to keep in mind that it indicates not only a possibility of complicated disease status regardless of its association with stones but also a difficulty of applying a minimal invasive procedure and relatively increased length of hospital stay.
