Anatomie des ösophagogastrischen Übergangs

Zusammenfassung

Der ösophagogastrische Übergang erlangt zunehmend Bedeutung, da sich in diesem Bereich Adenokarzinome entwickeln, deren lokalisatorische Zuordnung Schwierigkeiten bereiten. Die vorliegende Arbeit gibt einen Überblick über wichtige anatomische Strukturen in diesem Bereich, die für die Sicherung des Abschlusses des Magens gegenüber dem Ösophagus verantwortlich sind. Außerdem werden sowohl die Schleimhautverhältnisse unter gesunden Bedingungen als auch deren pathologische Veränderungen bei der ösophagogastrischen Refluxerkrankung bzw. einer Helicobacter-pylori-Infektion dargestellt.

Abstract

The oesophagogastric junction is increasingly gaining importance due to the difficulty of allocating adenocarcinomas that develop in this region to the stomach or the oesophagus. The present article gives an overview of important anatomic structures in this area, which are responsible for the closure of the distal oesophagus and the entry of the stomach. Moreover, the structures of the mucosa in healthy and under pathological conditions (e.g., oesophagogastric reflux disease and infection with Helicobacter pylori) are discussed in this article.
