We succeeded in viewing the image of pancreatic duct on a TV monitor as a sequentialelectronic endoscope image by connecting a converter with a charge-coupled device toan ultra-thin pancreatoscope. Spacial image processing by adaptive enhancement, usingan electronic endoscope, was studied in the pancreatoscope images of 18 cases (10 withpancreatic cancer and 8 with chronic pancreatitis). As a result, it became clear that theimages obtained in Peak 2 of adaptive enhancement are much better than the originalimages. There was an excellent effect of clearly detecting the characteristic mucosalpatterns in pancreatic cancer and chronic pancreatitis. We are convinced that thismethod would be very useful in improving the diagnostic ability of pancreatic cancerusing an ultra-thin pancreatoscope.
