Hardware disease

As a foreign body disease ( Indigestio a corporibus alienis, traumatic reticuloperitonitis ) is called in ruminants a recording of a foreign body through the mouth, the bores in the reticulum through the wall and damaged organs in the neighborhood of this forestomach. The disease is due to the poorly selective feeding behavior before, especially in adult bovine animals.

Pathogenesis

The esophagus opens out in ruminants approximately at the level of the junction between the rumen and reticulum. Heavier particles and, therefore, foreign body thus arrive primarily in the reticulum. Since all stomach departments of intensive motor skills subject, mainly due to sharp foreign body impale these movements into or through the wall of the reticulum through. Common triggers of the disease are nails or pieces of wire pasture.

The reticulum adjacent next to the rumen a number of organs. Since these foreign bodies are always loaded with bacteria, there is infection and inflammation of these organs or to the formation of abscesses. This affects the peritoneum ( peritonitis traumatic ), spleen ( Lienitis traumatic ), the liver (hepatitis traumatic ) and the diaphragm ( Diaphragmitis ). It may also happen that a foreign body also pierced the diaphragm and organs in the chest cavity, such as the pleura ( pleurisy traumatic ), lungs ( pneumonia traumatic ) and especially the pericardium ( pericarditis traumatic ) are affected. In the pericardium dominates the increased formation of pericardial fluid and a pericardial tamponade, which greatly affects the heart in its action.

Clinical picture

The clinical picture is very different depending on the affected organ. Often, only non-specific digestive disorders are. At a traumatic pericarditis, there is a failure. Pneumonia causes respiratory disorders.

Diagnosis

For metallic foreign body foreign body detection equipment ( metal detectors ) can be used.

In addition, the diagnosis of so-called foreign body specimens can take place. In most cases, there is a hypersensitivity ( hyperesthesia ) in the descending part of the withers, since the Headsche zone (see dermatome ) of the anterior abdominal cavity is located. Here is raised in the so-called a skin fold and released at the time of expiration. At the back handle a deflection of the back is triggered by a fixed pinching in the transition from the breast to the lumbar spine, which leads in the hood area at a stretch. In the sample rod, a rod at the rear end of the sternum is passed under the animal and then raised strong. The tapping (percussion) of the thorax on the left side in the 6th to 8th intercostal space is another method. In the positive case, the animal shows at these tests is pain response in the form of a silent groans.

Therapy

Treatment is surgical, by opening the abdominal cavity and the rumen through which one proceeds to the hood and the foreign body removed.

Prophylaxis

Prophylaxis consists in a good pasture hygiene ( Absammeln of foreign bodies, removal of residues during repair of pasture fences ). Metallic foreign bodies may be trapped by the so-called cage magnets that are permanently placed in the forestomach.
