The recent development of the duodenoscope made the blind region smaller and more precise observation possible. However, the endoscopic observation of the pyloric ring from duodenal bulb side is still impossible. In order to observe this area, we have tried our new original technique, that is, intrabulbar inversion method using side viewing duodenoscope JFB and JFB 2. We have obtaind good result for observation of the pyloric ring and its neiboring areas from duodenal bulb side. The pyloric ring of 15 cases out of 22 were observed well. Among them, one case with duodenal ulcer, two with duodenal ulcer scar and one with polyp near the pyloric ring were diagnosed correctly. Moreover, it was possible to obtain the biopsied specimens from that polyp. With above mentioned inversion method, these follow-up cases were mainly studied in this report.
