title: [Closure systems of the gastrointestinal tract and their surgical significance].
abstract: The closure systems of the gastro-intestinal canal are based on three major forms, constrictive sphincter, dilatory closure, and kinking closure. A constrictive sphincter is attached to the oesophageal inlet and a dilatory closure to the cardiac orifice. Reflux oesophagitis may result from failure of dilatory closure. Helical fibres in crosswise arrangement rather than isolated sphincters are recordable from the pyloric region. Their function is identical with that of dilatory closure. The principle of kinking closure applies to the Papilla Vateri and the ileocecal valve. Conclusions are suggested for therapeutic approach problems of the closure systems.
