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.
在牛的诊疗实践中，前胃各部分的手术用于诊断和治疗多种疾病，包括创伤性网胃炎、网胃周围脓肿、迷走神经性消化不良和谷物过食症。通过左腹胁部剖腹术，首先通过触诊探查腹腔前部有无粘连或肿块。瘤胃切开术可对瘤胃和网胃的内腔进行全面检查。疾病的手术矫正可能需要排空瘤胃、取出异物或通过网胃排出脓肿。对于一些脓肿，需要进行单次抽吸和冲洗脓肿包膜，或在腹中线剖腹术后通过体壁排出脓肿。如果与疾病相关的粘连不影响前胃的神经支配，病牛在牛群中恢复功能状态的预后良好。涉及网胃内侧壁的粘连或因创伤性网胃炎蔓延导致的心包和心肌疾病预后很差，因此对于受影响的病例应考虑屠宰。
