Resumen

Background: Type I and type IV-A choledochal cysts (CC) in Todani’s classification are the most frequent types of CC. Unlike type I cyst, in which the dilatation is confined to the extrahepatic bile duct, type IV-A affects both extra and intrahepatic ducts. Aim: To review our experience of complete cyst excision with Roux-en-Y hepaticojejunostomy for the treatment of type I and type IV-A CC in childhood, in order to better characterize these entities. Material and methods: Data was collected retrospectively from a cohort of children who underwent cyst resection for CC from 1989 to 2011 in our institution. Results: Twelve patients were submitted to surgical excision of extrahepatic cyst and hepaticojejunostomy for treatment of type I (n = 6) and type IV-A (n = 6) cysts, with a complication rate of 25% (n = 3) and no mortality. Long term follow-up was available in 92% of patients, with a median of 10 years (2-22 years). Morbidities consisted of bile leak (2 patients) and late-onset cholestasis (1 patient); two of these required anastomotic revision. The results did not reveal any significant differences between the groups regarding postoperative outcomes (P > 0.05). Preoperative intrahepatic dilatation was found to permanently vanish in 83% of patients diagnosed with type IV-A cyst after operative repair. Conclusions: Intrahepatic dilatation of type IV-A cyst in children did not adversely affect the postoperative outcome after conventional surgical repair. This operative approach was effective in the management of type I and type IV-A cysts.
