抄録

The smaller caliber forward-viewing fiberscope designated as Olympus GIF-P₂ was described and its clinical use in 897 patients was reviewed. The major advantages of the GIF-P₂ are improved flexibility and maneuverability. The instrument was employed not only for routine upper GI endoscope but for many purposee as follows; (1) retroflexion in the esophagus and duodenal bulb, (2) further examination of operated stomach, (3) pediatric diagnostic upper GI endoscopy and removal of foreign bodies, (4) functional endoscopic examination of upper GI tract, (5) ergent endoscopy, (6) polypectomy, (7) snare biopsy (Schilingenbiopsie), (8) FRCP, (9) peroral direct cholangioscopy (PDCS) through incized papilla after endoscopic papillotomy (EPT) and (10) ERCP and EPT after Billroth II resected stomach. The GIF-P₂ is evaluated superior to other standard panendoscopes and offers many improvement and advantages.
