Videothoracoscopy Versus Thoracotomy for the Diagnosis of the Indeterminate Solitary Pulmonary Nodule

Division of General and Thoracic Surgery, University of Milan, Milan, Italy

Accepted for publication October 27, 1994.

The solitary pulmonary nodule often presents a diagnostic challenge to the specialist because the nature of the nodule is often indeterminate at the end of the usual diagnostic process, and operation frequently is required before a definite diagnosis can be made. We have conducted a randomized, prospective trial to evaluate the diagnostic efficacy of video-assisted thoracic surgery versus muscle-sparing lateral thoracotomy. Between January 1991 and May 1994, 44 patients suffering from solitary pulmonary nodule were divided at random into two groups: the nodule was removed in 22 cases by video-assisted thoracic surgery and in 22 cases by lateral thoracotomy. Nineteen wedge resections, 1 segmentectomy, and 2 lobectomies were performed in the first group and 13 wedge resections, 8 segmentectomies, and 1 lobectomy in the second group. An ``access'' thoracotomy had to be performed in 5 patients in the video-assisted thoracic surgery group. The operating room time was 97.2 +/- 32.9 minutes in the video-assisted thoracic surgery group and 130.5 +/- 14 minutes in the lateral thoracotomy group (p > 0.05). In both groups a final diagnosis was made in 100% of cases. The postoperative hospital stay was 4.6 +/- 1.08 days in the video-assisted thoracic surgery group and 7.8 +/- 0.89 days in the lateral thoracotomy group (p < 0.01). Pain was evaluated on a visual analogue scale; the scores were 26.5 +/- 11.6 in the video-assisted thoracic surgery group and 48.3 +/- 12.8 in the lateral thoracotomy group (p < 0.05). On the basis of the results obtained in this trial, video-assisted thoracic surgery seems to be as effective as lateral thoracotomy in the diagnosis of solitary pulmonary nodule, but causes less discomfort to the patients and requires a shorter period of hospitalization.
