title: Needle-localized thoracoscopic resections of small indeterminate pulmonary nodules in transplant patients.
abstract: Indeterminate pulmonary nodules (IPN) in transplant patients create a diagnostic and therapeutic challenge. Patients who are transplant candidates or have already undergone organ transplantation require diagnostic clarification of IPN which may represent oncologic and/or infectious disease processes. Between December 1991 and January 1993, we performed 43 needle-localized thoracoscopic resections (NLTR) on 40 patients for IPN considered too small for less invasive diagnostic techniques. Four of these patients were candidates for orthotopic liver transplantation (OLT) and required exclusion of either extrahepatic malignancy or pulmonary infection before proceeding with transplantation. The 5th patient had undergone OLT for an unresectable hepatocellular carcinoma, and NLTR confirmed the presence of pulmonary metastatic disease. Of the 4 OLT candidates, 2 had pathologically confirmed metastases from their primary hepatic malignancy and did not undergo transplantation. The remaining 2 OLT candidates had benign pulmonary processes (hamartoma, hyaline plaque) and underwent successful OLT. In all patients, the IPN was successfully identified with NLTR. There were no complications. NLTR is a reliable and well-tolerated method to diagnose IPN in transplant patients.
