There is no longer anyactual difficulty in making the food pass down, but sooner orlater it is brought up again—the lower down the obstructionand the greater the degree of dilatation the longer will thefood be retained, so much so that in marked cases a diagnosisof pyloric obstruction is not at all infrequently made.
