Complications of thoracoscopy.

Although thoracoscopy has been a part of thoracic surgical practice for many years, the advent of video-assisted techniques has greatly expanded the indications and the uses of this procedure. Where previously thoracoscopy was performed mainly for diagnostic purposes, it now has assumed a major role in the therapy of chest pathology. In an attempt to inject a modicum of perspective into the tremendous enthusiasm that has accompanied the meteoric rise of video-assisted thoracoscopy, we have reviewed the experience at the Hospital of the University of Pennsylvania accumulated over the 1-year period from December 1991 to December 1992, specifically looking at complications resulting from the thoracoscopic procedure. During this period we performed 266 thoracoscopic procedures with no deaths. The overall incidence of complications was 10%, with the most prevalent complication being prolonged air leak (3.7%). There were five superficial wound infections (1.9%) and 5 patients who bled significantly enough to require either transfusion or reoperation, or both. In 11 patients (4.1%), the proposed thoracoscopic procedure could not be completed as planned, and a thoracotomy was required. The incidence of complications is certainly acceptable and similar to that seen after thoracotomy, although overall hospital stay is shorter and patients seem to have less pain and return to normal activity sooner. One would expect the incidence of complications to further decrease as surgeons acquire more experience with this significant modification and improvement of an old technique.
