[Differential indications for peroral pancreaticoscopy].

Pancreatoscopy by the new mother-baby-endoscopy-system is an effective and safe diagnostic technique. Before the pancreatic duct can be entered by the pancreatoscope (diameter 3.2 mm), a sphincterotomy of the pancreatic sphincter must be performed. In 11 of 13 cases, the macroscopic and cytologic or histologic diagnosis respectively could be made. Main indications for this technique are intraductally localized lesions, where endoscopically guided cytology or histology can clarify the dignity of the lesion.
