Summary
Although previous gastroscopes have been called gastroduodenoscopes, most endoscopists
have had little success in visualizing even the duodenal bulb. We made a new instrument,
fiberduodenoscope (made by Machida), in order to observe the duodenum, especially
the papilla of Vater. With this fiberduodenoscope it is now possible to regularly
view the duodenal bulb and first portion and frequently the second and third portions,
including the papilla of Vater. Duodenal ulcer, polyp, diverticulum as well as cancer
of the papilla can be diagnosed endoscopically. In addition, we have cannulated the
papilla of Vater and injected the pancreatic duct with radio-contrast material.
Key-Words
Fiberduodenoscope - papilla of Vater - endoscopic pancreatography
