Abstract

Choledochal cyst is associated with biliary malignancies such as bile duct cancer and gallbladder cancer. We herein present a case of preemptive choledochal cyst resection during redo operation for incidentally detected gallbladder cancer following laparoscopic cholecystectomy. A 64-year-old female patient underwent laparoscopic cholecystectomy and gallbladder cancer was diagnosed. Imaging studies revealed that the patient had choledochal cyst with anomalous union of the pancreaticobiliary duct. Preoperative findings suggested that gallbladder cancer might have be developed due to the carcinogenic effect of the anomalous union of the pancreaticobiliary duct-associated pancreatic reflux. Thus, preemptive resection of choledochal cyst was performed with redo radical cholecystectomy. The patient recovered uneventfully. The tumor stage was T2N0M0, tumor-node-metastasis stage II. The patient has been undergoing adjuvant chemotherapy. The present case suggests that preemptive bile duct resection can be considered in gallbladder cancer patients with anomalous union of the pancreaticobiliary duct and asymptomatic choledochal cyst.
