A case of obstruction of the colon by a solitary, large gall-stone is described. This rare event usually occurs in elderly females in whom there is frequently an underlying pathological condition at the site of obstruction in the colon. ⋯ Diagnosis may be assisted by plain abdominal X-ray and contrast radiography. Immediate operative treatment should be tailored to the patient's general condition and the nature of the pathological changes.
