Below is a brief list of problems associated with the large colon. Typically, these are non-surgical and can be resolved with some medical management. That's not ALWAYS the case, but for the most part it is. (Part 2 will focus on more severe types of large intestinal colic.)
Other types of impactions include cecal impactions, where a large amount of feed material becomes trapped within the cecum, and small colon impactions, which tend to be more common in miniature horses. These can be more difficult to treat, but still follow the same pattern as pelvic flexure impactions.
The mainstay of treatment for any of these is fluids, fluids, and more fluids. Absolutely no food should be given to horses with an impaction (or any colic for that matter), as it will continue to build up and make the impaction harder to move. Many times we can pass a tube and administer oral fluids to get everything moistened up and moving again. Other times, we may need to re-hydrate the patient with a combination of IV and oral fluids. Occasionally, these can become severe enough to require surgery.
Stay tuned for Part 2 where we'll discuss more serious and surgical types of large intestinal colic.
