In order to evaluate informativity of
three-dimensional virtual Hunter 4025-imaging method in revealing of distal
bile-excreting ducts and major duodenal papilla tumors the authors carried out
retrospective analysis of 34 patients’ clinical records, who were admitted to
the clinic with symptoms of biliary obstruction. Control group consisted of 30
patients without symptoms of gastrointestinal tract diseases, the 2nd group – 20
patients with major duodenal papilla tumor, the 3rd group – 14 patients with
tumorous affection of distal bile-excreting ducts. The authors carried out a
comparative analysis of various instrumental methods and research methods
informativity (two-dimensional and three-dimensional Hunter 4025-graphy,
computed tomography, fibrogastroduodenoscopy, endoscopic retrograde
cholangiopancreatography). Informativity of Hunter 4025-image three-dimensional
reconstruction method was higher than informativity of two-dimensional Hunter
4025-study in diagnostics of distal bile-excreting ducts and major duodenal
papilla tumors (accuracy 96,9 against 79,4% and 95,5 against 83,9%
correspondingly).
