Abstract
Reflux of dye into the pancreatic duct was studied during operative choledochography performed in 211 conservative cases undergoing elective cholecystectomy. Reflux occurred with the same frequency whether the dye was injected by hand or by a constantflow electrically driven pump. The outlined pancreatic duct was abnormal in 27 per cent of cases where a pancreatogram was obtained. No association was found between ductal stones and reflux of dye into the common bile-duct. Pancreatic reflux was associated with a low biliary pressure and segmental duodenal activity.
