title: Nonanatomic thoracoscopic wedge resection for diffuse lung disease and indeterminate pulmonary nodule.
abstract: Video technology has revolutionized thoracoscopy dramatically, considerably increasing its indications. The clinical charts of patients who underwent a video-thoracoscopic procedure during a 6-year period were reviewed. Any patient in whom lung wedge resection for diffuse disease or an indeterminate nodule was performed met the inclusion criteria. Early and long-term outcomes were analyzed. A total of 310 thoracoscopic procedures were performed in the 250 patients reviewed. Of these patients, 60 presented with diffuse lung disease and 71 with an indeterminate pulmonary nodule. The total morbidity among diffuse disease patients was 5% (one intercostal vessel hemorrhage and two air leaks). Overall mortality for this group was 11% and was related to previous respiratory status and underlying disease. Patients not requiring preoperative mechanical ventilation ended up requiring it postoperatively, for a crossover rate of 23%. There was no morbidity or mortality in patients who did not require mechanical ventilation. The therapeutic impact index (defined as the total number of patients divided by the patients in whom initiation or withdrawal of specific treatment was due to the biopsy result) for diffuse lung disease was 0.9. Regarding lung nodule resection, early morbidity was present in one patient, who developed a persistent air leak. Late morbidity was present in three patients, who developed persistent intercostal pain. Total morbidity was 5.6%. No mortality was observed for this group. Nonanatomic wedge resection via video-thoracoscopy for diffuse pulmonary disease and indeterminate lung nodule is feasible using minimally invasive methods. Morbidity and mortality are related to the underlying disease and the respiratory status; they are not necessarily due to the procedure.
