title: One case that developed bile duct cancer all over the progress of repeated cholangitis.
abstract: A 65-year-old man was referred to our department due to repeated episodes of cholangitis in the past five years. Endoscopic retrograde cholangiopancreatography was performed, and a stricture of the lower bile duct was detected. At a later date, an irregular mucosa of the bile duct was confirmed using nasal endoscopy. Based on the biopsy results, the patient was diagnosed with bile duct cancer and subsequently underwent surgery. Postoperative histopathology did not show lymph node metastasis, and the condition was determined to be early-stage bile duct cancer. In the present case, it was presumed that the cancer had developed due to chronic cholangitis. Therefore, in patients with repeated episodes of cholangitis, attention should be focused on the possible and concomitant development of cancer.
