Abstract

Motion pictures of the lining and behaviour of the stomach can provide improved diagnosis without risk to the patient. The problem of illumination to achieve successful cinegastrography with the standard gastroscope and the fiberscope is reviewed, and the optical properties of the instruments evaluated. A detailed account, and diagrams of the design of units for taking motion pictures which use internal and external illumination, is presented.

Sommaire

Le filmage des parois et du comportement gastriques fournit des éléments de diagnostic précieux, sans entrainer de risques pour le patient. L’emploi des gastroscope et fibroscope courants en cinégastrographie comporte un problème d’éclairage sérieux, si l’on veut obtenir des résultats édifiants à partir de ce procédé. Ce problème est étudié et les qualités optiques des instruments sont évaluées. Les divers composants d’un appareil de cinégastrographie fonctionnant à l’aide d’éclairage, interne et externe, font l’objet d’un compterendu détaillé avec diagramme.

Zusammenfassung

Mit Filmen der Magenwand und ihres Verhaltens kann man ohne Risiko für den Patienten verbessertes diagnostisches Material erhalten. Die Frage der für erfolgreiche Gastroikinematographie notwendigen Beleuchtung wird für das Gastroskop und das Fiberskop erläutert, und die optischen Eigenschaften der Instrumente werden gegenübergestellt. Für Geräte, die mit innerer und äußerer Beleuchtung arbeiten, werden detaillierte Beschreibungen sowie Diagramme gegeben.
