Six years' experience with perthoracic core needle biopsy in pulmonary lesions.

Abstract

Six years' experience of percutaneous core needle biopsy using the Hausser needle in 502 patients, aged 20-89 years, is reported. A biopsy was carried out when sputum and bronchoscopic methods had failed to establish a definitive histological diagnosis. Over 60% of the lesions were peripheral and about 40% were 24 cm in diameter. A correct diagnosis was made by this means in 312 of the 339 patients shown eventually to have a malignant lesion (92%) and in 130 of 146 patients with a benign lesion (89%). A definitive diagnosis was never established in 17 patients. Complications arose in 15% of cases. Pneumothorax occurred in 43 patients (7%), of whom 12 required a chest drain. Further complications included a small haemoptysis (<30 ml) in 27 patients (5%), haemothorax necessitating a chest drain in three patients, and an intrapulmonary haematoma in five patients. There were no fatal or permanent complications. Percutaneous core needle biopsy is a valuable procedure with a high diagnostic accuracy in these patients and a low rate ofcomplications.

“…In another study using trucut biopsy for lung lesions by Morgenrotet al 7 in 1988 reported a diagnosti c yield of 89% for accurate cytopathologicaldiagnosis.This study reported a complicati on rate of 15% and citi ed a complicati on rate of 10% to 60% from other studies. Şerife et al 8 in 2010 reports a cytopathological yield of trucut biopsy of lung lesions of more than 95% and a complicati on rate of more than 25%.…”
