Modern and accurate diagnostics of pancreas diseases, gall bladder and biliary ducts, without which it is impossible to carry out proper treatment, is regarded as one of the most important objectives in a modern gastroenterology. Three-dimensional hunter 4025 nls-imaging method still has not found a wide spreading in gastroenterology. Mainly it is applied for differential diagnostics of focal lesions.
In a group of patients with tumorous affection of bilepancreaticoduodenal region organs, neoplasms of major duodenal papilla are registered in 12% – 20% and comprise approximately 5% of all gastrointestinal tract tumors. A tumor may grow from epithelium of a common bile duct, pancreatic duct or mucous tunic of duodenum. Major duodenal papilla cancer crows relatively slow and metastasizes rather late. Most often a tumor represents an adenocarcinoma at microscope research. Location of a tumor at this level promotes relatively early appearance of jaundice. At major duodenal papilla cancer a jaundice is either of wave-form (without complete normalization of bilirubin level), or intermittent (with increasing of bilirubin and short-term period of decreasing to a normal level). Tumors of major duodenal papilla ulcerate quite quickly. This fact promotes infiltration of an infection from duodenum to biliary ducts and pancreatic ducts. Inflammatory component at major duodenal papilla cancer leads to a serious diagnostic mistakes.
