The value of thoracoplasty.in the treatment of advanced pulmonary.tuberculosis has stood the test of time during the past twenty.y.ars. Late results, from one to ten y.ars after the operation, from American clinics showed that about sixty.per cent of patients were clinically.cured and another fifteen to twenty.per cent were improved (1, 2, 3, 4, 5). The immediate mortality.rate is less than 5% by.number of patients. and about 3% by.number of operations. These figures are certainly.encouraging as compared with the results of treatment without collapse therapy.(6, 7) or those following pneumothorax (8, 9). But in spite of this achievement, the number of such operation.s in China is still small, considering the large number of patients suffering from advanced pulmonary.tuberculosis. The *** is based upon the data compiled from 125 stages of thoracoplasty.in 55 patients operated on by.the author or his assistants during a four and one-half y.ar period from July. 1944 to December, 1948. Thirty.six cases were treated at the Chungk.ng Central Hospital; 14 cases at the Tientsin Central Hospital, and 5 cases at the Peiping Union Medical College Hospital. No attempt is made to go into the technical aspects of the procedure. The material is analy.ed with emphasis on the results of the treatment and the various factors concerned in the selection of patients for the operation.

Achalasia of the esophagus is also k.own as cardiospasm, megaesophagus, and idiopathic dilatation of the esophagus. It was first described as a disease entity.in 1674 by.Willis (1) and later by.Purton in 1821 (2). It denotes a condition in which the contents of the esophagus find difficulty.in empty.ng into the stomach.
