Bilateral lobectomy for bronchiectasis has seldom been attempted. Eloesser,1Edwards2and Lewis3have each reported a case. In the series of surgically treated bronchiectasis patients of Churchill,4four successful bilateral operations were done. These few reports would indicate that surgical extirpation of lobes from both the right and left lungs has been considered even more difficult of attainment than the removal of all the pulmonary tissue on one side. However, bronchiectasis is found in far greater frequency in both lower lobes or in the left lower and right middle lobe than it is found to be limited to the upper and lower lobes on the same side. Therefore in the treatment of this disease the thoracic surgeon will in the future be asked to consider bilateral lobectomy more often than pneumonectomy. The following case, in which the right middle, right lower and left lower lobes were successfully resected
