In contrast to the large thoracotomy incisions required by standard surgical techniques for repair of diaphragmatic eventration, the procedure we developed can be performed by video-assisted thoracoscopy, thus offering patients the advantages of a minimally invasive operation. Using two superposed series of transverse back-and-forth continuous sutures, the diaphragm is invaginated, then stretched. The first suture line holds the diaphragm down and maintains the excess within the abdomen; the second suture line places the desired tension on the diaphragmatic dome. Successful repair of 3 cases by this technique is described.
