Surgery of the bovine forestomach compartments

Surgery of the forestomach compartments is performed in bovine practices for the diagnosis and treatment of many diseases, including traumatic reticuloperitonitis, perireticular abscess, vagal indigestion, and grain overload. Through a left flank laparotomy, the cranial abdomen is first explored by palpation for adhesions or masses. A rumenotomy allows thorough examination of the lumen of the rumen and reticulum. Surgical correction of disease may require emptying of the rumen, removal of a foreign body, or drainage of an abscess into the reticulum. With some abscesses, single aspiration and lavage of the abscess capsule or drainage of the abscess through the body wall, following a ventral celiotomy, is required. If adhesions associated with disease do not affect the innervation of the forestomach, the prognosis for return to functional status within the herd is good. Adhesions involving the medial wall of the reticulum or pericardial and myocardial disease due to extensions of traumatic reticuloperitonitis have a very poor prognosis, and thus slaughter should be considered in affected cases.
