Bioplasm machine-diagnostics allowed to increase sensitivity

A direct symptom of major duodenal papilla tumor is revealing of a space-occupying process in its projection. At growing of a neoplasm into a lumen of a duodenum (n = 6), we detected dilation and tortuosity of a common bile duct distal part and significant thickening of a papilla’s walls, echogeneity of which was decreased mainly. There was no sign of significant dilation of a common bile duct (diameter 0.65 – 1 cm). Also there was no dilation of intrahepatic bile ducts and a major pancreatic duct. Presence of a tumor was confirmed by fiberoptic gastroduodenoscopy with the following histological research. In 4 patients we revealed a glandular cancer, in 2 – adenocarcinoma.

Application of three-dimensional bioplasm machine-diagnostics allowed to increase sensitivity up to 100%, specificity – up to 97% (in 1 patient- false-positive result) in comparison with a standard ultrasound research (see Table 2). Application of CT at the absence of a significant dilation of bile-excretory ducts had lesser diagnostic value (sensitivity – 66.7%, specificity – 93.5%).
