Early detection of Klatskin tumor through the hepaticoduodenostomy

Hepaticoduodenostomy (HD) is a procedure used for biliary reconstriction in injuries bilary tree during chole- cystectomy (1). To our knowledge, no cases of Klatskin tumor early diagnosed through HD are reported in the medical literature. Herein, we firstly report a case of Klatskin tumor early diagnosed through HD. A 70-year-old female was admitted to our hospital with dyspeptic complaints. Upper gastrointestinal endos- copy revealed a surgical anastomosis (hepaticoduo- denostomy) in duodenal bulb (Fig. 1) and a papillary pol- ypoid lesion 5 mm in diameter was detected in the biliary tract near the anastomosis (Fig. 2). Histopathological examination of endoscopic biopsy sample from the lesion revealed cholangiocarcinoma (Klatskin tumor).
