Video-assisted thoracic surgery: Manipulation without trocar in 112 consecutive procedures

Since learning of the video-assisted thoracoscopic techniques in the treatment of thoracic diseases, we have encountered many problems and difficulties because of the limited trocar space and lack of suitable instrumentations. Since March 1992, we have found a simple and easier way to perform this procedure, that is, manipulating through the extended incisional wound without using a trocar. Endoscopic and conventional thoracic instruments are able to pass through the incisional channel freely and manipulate similarly to the technique used in open thoracotomy. All the patients had less postoperative pain, reduced operative time, and prompt return to employment. The technique is effective and is herein described.
