Sequential rectal examinations are the cornerstone of colic diagnosis, as many large intestinal conditions can be definitively diagnosed by this method alone. Rectal examination is invaluable in the diagnosis of medical problems such as primary impactions and spasmodic colic, and also in determining the severity of the disease and if surgery is necessary. Many subtle changes can be detected before they become apparent clinically or in the peritoneal fluid. A thorough rectal examination is vital for the early diagnosis and referral of surgical cases which improves the prognosis and post operative survival.
