title: [Diagnosis of early gastric cancer using transnasal endoscope].
abstract: Transnasal endoscopy (TNE) with ultrathin endoscope has been gaining popularity in Japan as a safe and painless upper gastrointestinal procedure, whereas lower resolution of small CCD is the problem which now confronts us. However ultrathin endoscope has made tremendous progress in these ten years. Its latest model has high-resolution equal to conventional endoscope. Actually the detection rate of gastric cancer in our health check-up center is 0.19% and the false negative rate is 35.3%, so we consider there is no significant difference in the diagnostic capability between TNE and conventional endoscopy. Furthermore we think that improvement of endoscopist's power of observation, preparation to clean up the gastric wall as well as the resolution of endoscope are required for detecting gastric cancers in its early stage with TNE.
