When is rumenotomy indicated in forestomach disorders?

• A. For routine checkups and mild distension.
• B. For transient ruminal gas buildup resolving with medical therapy.
• C. For severe, refractory ruminal acidosis or distension not responding to medical therapy, requiring rapid decompression or removal of ruminal contents.
• D. For evaluation of rumen microflora without distension.

Answer: (C)

Rumenotomy is reserved for emergencies where the rumen is severely distended or dealing with severe acidosis and cannot be controlled quickly with medical therapy. In these cases, rapid decompression or removal of ruminal contents is life-saving, so surgically opening the rumen allows immediate relief of gas buildup, removal of harmful substrates, and stabilization of the animal. It’s not used for routine checkups or mild distension that responds to medical treatment, nor for situations where you’re simply evaluating rumen microflora without distension. The procedure carries risks, so it’s chosen only when medical management fails or when rapid relief is essential.
