The authors reported our experience of the new video endoscope (XGIF-1T230Y) in clinical use. Olympus Company newly developed this model for endoscopic treatment of upper gastrointestinal tract, which is characterized by a larger biopsy channel (3.7mm in caliber) . The larger channel was extremely useful for endoscopic balloon dilatation to post-operative esophageal stricture, because the balloon was smoothly put in and out through the channel without any damage.
Furthermore, endoscopic hemostasis was easier using this model, since coagulated blood was sucked effectively through the channel and the clots on a bleeding site was removed by a flush of water through newly equiped wash-out channel. It was concluded that this endoscope is very useful any for kinds of endoscopic treatment.
We, further, hope that new divices would be developed fitting a larger channel to perform treatment more easily, safely and certainly.
