THE STUDY ON STANCH CLIPS FOR THE TREATMENT BY ENDOSCOPY

Abstract

Heretofore, it has been regarded to carry out endoscopic examinations on the patients bleeding from the digestive tracts. However, recent improvement in endoscopic apparatus and the diagnostic techniques in Japan have made it possible to carry out an urgent endoscopy within a short time after the bleeding; so that we are able to locate the bleeding sites very soon, make a correct diagnosis and given necessary first aid and treatment accordingly. On behalf of this purpose we have been studying stanch methods for the treatment by endoscopy and we made two types of stanch clips for the bleeding from digestive tracts and for the bleeding after polypectomy by f iberscope. The type "A" clips is for small lesions like de-veloped vessel end from bottom of the ulcer and type "B" is bigger than type "A", for larger lesions like bleeding after polypectomy. These clips are used from forceps-canal of f iberscope same as forceps for biopsy, also used not only for the urgent cases but for followings; to recognize the border between oesophagus and cardial mucous, to obtain knowing anterial and posterial walls of duodenum by X-ray examinations and marking of the lesions in the case of surgioal operations, etc. The type "A" clips was made so small, its length is 5.0mm, width is 1.5mm and 0.05 grams in its weight.
