Abstract
Two patients with the anomalous pancreato-biliary ductal system accompanied with cancer of biliary tract, which is very uncommon, are reported.
One patient, a 38 year-old woman was adomitted to the hospital complaining of epigastralgia and jaundice. ERCP (Fig 1) revealed the anomalous pancreato-biliary ductal system associated with choledochal cancer after decompression of biliary truct by ERBD procedure (Fig 2), choledocho-jejunostomy was performed successfully. Occasionaly, cancer at the fundus of the resected gallbladder was found. Other patient, a 50 year-old woman was adomitted to the hospital due to liver dysfunction. US (Fig 3) revealed tumor of the gallbladder. ERCP (Fig 4) showed the anomalous pancreato-biliary ductal system and filling defect in the fundus-body region of the gallbladder. Pathologically it was found that cancer cells were localized within mucosal layer of the gallbladder. The clinical entity seen in these two cases encounter very rarely. This sort of lesion have been described as duplicately-jointing type or ramifiedcommunication type.
