| [ Summary ] | We have diagnosed pancreatic diseases by using peroral pancreatoscopy (PPS). PPS findings concerning pancreatic cancer included: stenosis (51%), obstruction (46%) redness (43%) bleeding (42%), floaters (42%), rough mucosa (39%), and scar-like-appearance (13%). Findings in chronic pancreatitis are; floaters (71%), scar-like-appearance (56%), stenosis(47%), stones(15%), redness and erosion(8%), rough mucosa (6%), obstruction(5%). Rough mucosa, and obstruction are characteristic in patients with pancreatic cancer. On the other hand, a stone and scar-like-appearance is recognized in patients with chronic pancreatitis rather than in pancreatic cancer. Stenosis with smooth mucosa or with scar-like appearance is seen in chronic pancreatitis. Obstruction and the stenosis, with erosion, are seen in pancreatic cancer. PPS is most useful for observation of papillary tumors in patients with intraductal papillary mucinous tumors. PPS has become indispensable in the diagnosis of pancreatic diseases. |
