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

Abstract

1. The proposed undirect bulboscopy by means of the standard type of gastroduodenal fiberscope (ACMI) rests on the observation of the bulbal cavity through the opening of the pyloric canal.The instrument lies in the distal part of the antrum.The method is, compared with the direct duodenoscopy (Hirschowitz) a simple procedure.Pathological changes in the bulb can easily be seen especially in a case of duodenal ulcer.The author by this method diagnosed 111 duodenal ulcers. From these 61 were formerly diagnosed by X-ray studies (55°1o), in 18 patients the Downloaded by: National University of Singapore. Copyrighted material.

Fibreoptic endoscopy and the barium meal--results and implications.

“…These figures refer mainly to repeated studies in patients with symptoms severe enough to warrant operation. Endoscopic series suggest that 20-55% of duodenal ulcers escape radiological detection.3 24 (table I). Since this is a selected group, our results cannot be extrapolated to all patients with negative x-rays.…”
