Objectives: The pulmonary nodule is an important diagnostic and therapeutic problem. Diagnostic certainty is only obtained by histological examination. Mini-invasive surgery allows removal of the nodule with minimal sequelae for the patient.
Methods: From October 1991 to December 2006, 370 resections for a pulmonary nodule were performed at our Department of General Surgery of the University of Milan: 276 wedge resections and 94 lobectomies.
Results: Frozen section was performed in all the wedge resections, and in the presence of cancer (77 cases), whenever possible (61 cases), the intervention was converted to lobectomy in the same session. In the other 94 cases, the nodule was removed by lobectomy due to the impossibility of performing a wedge resection.
Conclusions: Despite the refinement of diagnostic techniques, only exeresis of a pulmonary nodule ensures a definitive diagnosis, thus resolving the problem of benign pathologies and initiating the correct therapy for malignant lesions in the same session.
