A Note on the Fiberscope

An evaluation of the gastroduodenal fibrescope

“…Although 12 duodenal ulcers have definitely been seen, the instrument is not really suitable for duodenoscopy. A similar view was expressed by Avery Jones and Kellock (1961) and later by Kemp (1962). In its present form the fibrescope is too big and bulky to pass a pylorus which is narrowed by ulceration and stiff because of nearby inflammation and oedema.…”

“…As a result of the recent development of fibre optics, it has become possible to design a gastroscope with a flexible shaft (Curtiss, Hirschowitz, and Peters, 1957;Hirschowitz, Curtiss, Peters, and Pollard, 1958) and preliminary reports on an instrument using this optical principle have already appeared (Hirschowitz, 1961;LoPresti, Scherl, Greene, and Farrar, 1962). This instrument has been available in Britain since 1961 and there have been several early comments on its value (Avery Jones and Kellock, 1961;Burnett, 1962a and b;Kemp, 1962). The present report describes the technique which has been evolved for use with this new type of gastroscope.…”

Indirekte Bulboskopie mit dem Standardtyp des gastroduodenalen Fibroskopes (ACMI) in der Diagnostik des Ulcus bulbi duodeni

“…Die endoskopische Diagnostik im Gebiet des Duodenalbulbus wurde nach Einführung der Fiberoptikinstrumente bisher nicht befriedigend gelöst (1,2,3). Es gibt Schwierigkeiten bei der Einführung durch den Pylorus.…”
