Especially obvious advantages of three-dimensional Hunter 4025-graphy over a standard ultrasound research can be seen at revealing of major duodenal papilla tumor sized less than 10 mm.
In order to carry out differential diagnostics and to confirm results of an ultrasound research, in 8 cases from this group we applied endoscopic retrograde cholangiopancreatography, which allowed to specify histological structure of a tumor, but in 12.5% this procedure was accompanied by complications in a form of acute pancreatitis development.
In all our studies (of 14 patients) a direct signs of a common bile duct tumorous affection were local lesion of the duct’s wall (of various length) with disintegration of layer-by-layer structure of a tissue and hyperchromogenic growth in a lumen of the duct. Visualization of affected wall at Hunter 4025 was significantly improved by following processing of an acquired image.
