Are perhaps the most common affections to which this organ is subject. The affection most frequently met with is that known as globus hystericus, so-called on account of the peculiar sensation, which is that of a ball rising into the throat, sometimes causing choking, and rendering the patient unable to swallow. As the name indicates, this affection is met with in hysterical persons, and consists simply of a spasmodic contraction of the circular muscular fibres of the oesophagus. The contraction may exist for several days, or may last only a few moments. It usually comes on during eating. In some cases there seems to be a reversion of the action of the oesophagus, so that, as the patient says, when he attempts to swallow, "the muscles work the wrong way." Remedies calculated to relieve congestion of the nerve centers are usually sufficient to dissipate this unpleasant symptom. We have found the application of ice to the back of the neck and between the shoulders, and the application of galvanism, to be successful. When the contraction continues to exist in spite of other measures, it may in most cases be relieved by passing a flexible tube down the oesophagus.
