title: [Further investigations of insufficient stretching-closing mechanism of the terminal esophagus (author's transl)].
abstract: The anatomy of the closing mechanism of the terminal esophagus was studied in the dogs since this animal is frequently utilized for investigations of esophageal function. With the aid of a special method we have demonstrated a stretching-closing mechanism similar to that of the human subject. An operatively placed hiatus hernia with a tendency to reflux shows the expected reaction of the muscular screw mechanism. This insufficient stretching-closing mechanism is similar to an insufficient "ring sphincter". The reconstruction of the closing mechanism by means of "stretching and gastropexie" which has proven successful in practice is discussed.
