title: Two cases of gastric cancer-bearing double choledochus with ectopic drainage into the stomach.
abstract: Two cases of double choledochus with ectopic drainage into the stomach associated with gastric carcinoma were reported. The stomachs were resected because of the presence of cancer, and the orifices of the ectopic bile duct were found in the oral side of the lesions. In these two cases, hyperplasia of gastric foveolas and atrophy of fundic gland, with its cystic dilatation, were observed around the orifices. A possible correlation between direct flow of bile juice into the stomach through the ectopic bile duct and the development of gastric cancer was discussed. The literature regarding double choledochus was reviewed.
