ENDOSCOPIC POLYPECTOMY WITH USING A SMALL CALIBER FIBERSCOPE GIF-P₂

Abstract

The electrosurgical removal of polypoid lesion from the upper gastrointestinal tract with using a small caliber forward-viewing f iberscope (GIF-P 2) has proven to be a safe and effective procedure. Sixty one polypectomies performed on 40 different patients are discussed. Polyps were removed from the distal esophagus, stomach and duodenal bulb. Since a safety circuit for diathermic current is built into the GIF-P2, the operator is freed from worry about elertrical accidents caused by current leakage and can concentrate on the operation. The bending portion of the GIF-P2, which is shorter than those of previous instruments, gives improved handling inside the organs, makes approaching the target easy and makes snaring the polyp very easy. Furthermore, the small diameter of the instrument makes it possible to examine the patients with minimal discomfort. In all 40 cases the resected polyps could be recovered using the polypectomy snare, the grasping forceps, or the basket catheter. The method could be carried out in all patients without any complication.
