Such as tumors or fibrous tissue

Abnormal growths, such as tumors or fibrous tissue, producing contraction or stricture, may be causes of obstruction. The colic caused by these conditions is chronic. The attacks occur at gradually shortening intervals and become progressively more severe. Relief is afforded by the use of purgatives that render the feces soft and thin and thus enable them to pass the obstruction, but in time the contracted place is liable to close so far that passage is impossible and the horse will die.
