JEJUNAL DUPLICATION CYST COMMUNICATING WITH THE COMMON BILE DUCT

Jejunal duplication is a rare congenital anomaly of unclear etiology. It may communicate with the adjacent normal bowel. However, communication with common bile duct has not been described. Herein we report a case of jejunal duplication that communicated with the common bile duct in a 12 year old girl who presented with intestinal obstruction. Exploratory laparotomy findings were interpreted as huge choledochal cyst adherent to proximal jejunum. Excision of the cyst and proximal jejunum to which it was adherent was curative. After histopathologic evaluation and subsequent literature review for type II choledochal cyst with its etiopathologic considerations, the present case conforms to the diagnosis of jejunal duplication with communication to the common bile duct, the communication possibly being a congenital type. Such rare anomalies posing diagnostic and therapeutic challenge should be considered in the differential diagnoses of cystic abdominal lesions.
