Upward displacement of the diaphragm after lung resection.

Upward diaphragmatic displacement was performed in 53 patients after massive lung resection for tuberculosis or bronchiectasis and the data are presented. This technique provides ample room for expansion of the remainder of the lung; it also avoids overexpansion, activation of tuberculous foci, and relapse of bronchiectasis. Diaphragamatic displacement can be used for liquidation of a remaining infected cavity. In children with massive bronchiectasis it serves to conserve two unaffected segments and avoids pneumonectomy. During pneumonectomy in children it prevents significant shift of the mediastinum and progression of scoliosis.
