When a loop of intestine is trapped by a normal or abnormal abdominal structure, it is referred to as what type of colic?

Incarceration refers specifically to a condition where a loop of intestine becomes trapped or confined by either normal anatomical structures or by abnormal formations, such as adhesions or tumors. This entrapment can lead to a decrease in blood supply to the affected portion of the intestine, which may cause swelling, pain, and potentially more serious consequences like intestinal blockage or necrosis.

In the context of colic, which is essentially a term used to describe abdominal pain in horses, incarceration colic presents a distinct pathophysiological condition. The trapped intestines can lead to a series of complicated interactions, including changes to the motility of the intestines and potential rupture if not addressed.

Recognizing incarceration is critical for proper diagnosis and subsequent treatment because this form of colic often requires surgical intervention to relieve the pressure and prevent further complications. Understanding this concept enhances a horse handler's or evaluator’s ability to assess signs of pain and abdominal distress, supporting timely and effective management of such situations.
