In cattle, rumenal bloat caused by the obstruction is an emergency and requires immediate treatment. This is achieved by trocharisation through the left paralumbar fossa. Once the bloat has been relieved, the obstruction may be manually broken down via percutaneous massage, or may resolve spontaneously due to the large volume of saliva present. | In cattle, rumenal bloat caused by the obstruction is an emergency and requires immediate treatment.
