title: Forceps biopsy and suction catheter for sampling in pulmonary nodules and infiltrates.
abstract: Transbronchial lung biopsy with forceps is a standard procedure in bronchoscopic tissue sampling. Suction catheter aspiration is another technique, but it is not widely known and almost no data exist regarding its diagnostic efficiency. 272 patients were included in a prospective and randomised study between February 2007 and October 2009. All were referred for bronchoscopic evaluation of pulmonary nodules/masses or infiltrates. We compared the diagnostic yield of forceps biopsy and suction catheter aspiration for a definite diagnosis and looked at whether such a diagnosis depends on the underlying pulmonary change. All patients underwent bronchoscopy with forceps biopsy and catheter aspiration. A definitive diagnosis was reached in a total of 183 (67.3%) patients, with catheter aspiration in 140 (51.5%) patients and with forceps biopsy in 136 (50.0%) patients. In 90 (33.1%) patients, a definite diagnosis could only be reached with the combination of both techniques. The diagnostic yield of forceps biopsy was better than catheter aspiration in infiltrates (p = 0.027), but was no different in nodules or masses (p = 0.09). Suction catheter aspiration is a useful technique of bronchoscopic tissue sampling. The combination of catheter aspiration and forceps biopsy results in a higher diagnostic yield than either method used alone.
