  • Title: [Disorders of motility of the stomach and pylorus: pathological significance (author's transl)].
    Author: Blum AL, Siewert R.
    Journal: Leber Magen Darm; 1978 Aug; 8(4):184-90. PubMed ID: 28457.
    Abstract:
    Five different disorders of motility of the pyloric region may be distinguished if direction and velocity of chyme passing through the pylorus are taken into account: 1. Accelerated emptying of food and overacidification of the bulbus duodeni: 2. Bolus emptying of the stomach and rapid increasing hyperosmolarity in the small intestine: 3. Delayed emptying of the stomach and gastric retention: 4. Duodeno-gastric reflux and inflammatory lesions of the gastric mucosa: 5. Other disorders causing pain. Gastric disroders cannot yet be classified on the basis of abnormal motility patterns. It is well known, that the gastric and duodenal motility are regulated by two separate pacemakers located in the distal corpus area and in the bulbus duodeni. Thus it may be speculated that distrubed motility patterns may be due to abnormal pacemaker function.
