This case report presents the surgical management of a 55-year-old woman diagnosed with a type 2 choledochal cyst. The patient, with a history of right upper quadrant pain and normal liver function tests, underwent magnetic resonance imaging (MRI), which revealed common bile duct dilatation of up to 2 cm, confirming the diagnosis of a choledochal cyst. The surgical approach was meticulously planned, focusing on the identification of critical anatomical structures, including biliary variations and the right hepatic artery.
The patient was positioned in the French position, and the procedure was initiated with a cholecystectomy, followed by careful dissection and isolation of the common bile duct and right hepatic artery. The cyst was resected using harmonic and bipolar instruments, and a hepaticojejunostomy was performed with a side-to-side anastomosis. Intraoperative ultrasound ensured proper margins, and the procedure was completed with no complications.
Histological analysis confirmed the diagnosis without dysplasia, and the patient had an uneventful recovery, being discharged on postoperative day six. At 14 months of follow-up, no complications were observed.
