Megacolon Megacolon is a disorder created by a dilation and loss of motility of the colon, the last part of the large intestine. The end result is a loss of muscular function in the colon leading to chronic constipation and colonic dilation. The disorder may be present for months prior to clinical disease becoming apparent. The cause is not known but it affects cats of all ages with obese individuals at an increased risk. Diagnosis is achieved by using abdominal X-rays to evaluate the degree of colonic distension. Treatment is primarily by administering enemas and using colonic evacuation to initially deal with constipation, this may need to be performed under anaesthesia or sedation. The use of cisapride can improve colonic motility and in combination with stool softeners, such as lactulose, has proved effective. Easily digestible, low bulk diets with a degree of fiber supplementation are useful in managing megacolon. Too much fiber can, however, lead to excessively bulky faeces which can worsen colonic distension. Surgery is the last resort for treating this condition and should only be attempted when medical managment has failed. |
