Which technique involves inserting a trochar to release gas from the rumen?

• A. Stomach tube
• B. Trocharization
• C. Rumenostomy
• D. Laparotomy

Answer: (B)

Relieving ruminal gas by puncturing the rumen with a sharp instrument is trocharization. In this emergency procedure, a trochar is inserted through the left paralumbar fossa into the rumen to puncture it and allow the trapped gas to escape quickly, providing rapid relief in free-gas bloat. This contrasts with rumenostomy, which creates a permanent opening with a cannula for ongoing venting, and with a stomach tube, which non-surgically vents gas through the esophagus into the stomach. Laparotomy is an open abdominal surgery not primarily used to vent rumen gas.
