Early detection of biliary adenocarcinoma using probe-based confocal laser endomicroscopy: a case report

Bile duct adenocarcinoma is a malignant tumor, and early screening, diagnosis and treatment are crucial for improving patient prognosis. In this case, early cholangiocarcinoma was detected by a combination of choledochoscopy, biliary ultrasound, and biliary confocal endoscopy. The tumor and surrounding tissues were completely removed through pancreaticoduodenectomy. The operation was successful and the patient recovered well. Confocal microendoscopy shows great promise in the early diagnosis of digestive tract diseases, owing to its high-resolution imaging capabilities and potential to detect early lesions.
