title: [Endoscopic tumor-cell diagnosis within the region of duodenum].
abstract: The technique spontaneously or siphoned after cholecystokinin stimulation. Our technique of cell collection within the region of the duodenum, the pancreas and the bile-ducts have been optimal performed by duodenoscopical methods. From the papilla of Vater, the cell brush abrasion is used. Pancreatic secretions are obtained by praepapillary drainage with a catheter after secretin stimulation or siphoned after canulation of the ductus Wirsungianus. Bile is obtained wth the same technique of material collection and processing is described. Characteristical tumor cell findings of the papilla of Vater, of the pancreas and the bile ducts are demonstrated and the cytodiagnostic's position within the tumor recognition in this area is discussed. We think the tumor cell search with the described duodenoscopical techniques as indicated in following cases: 1. suspicion of carcinoma of papilla of Vater, 2.obstructve jaundice, 3. in search of carcinoma of the pancreas.
