RT Journal Article SR Electronic T1 Comparison of the Tru-cut biopsy needle with the Abrams punch for pleural biopsy. JF Thorax JO Thorax FD BMJ Publishing Group Ltd and British Thoracic Society SP 794 OP 796 DO 10.1136/thx.44.10.794 VO 44 IS 10 A1 D T McLeod A1 I Ternouth A1 N Nkanza YR 1989 UL http://thorax.bmj.com/content/44/10/794.abstract AB In a prospective study pleural biopsy specimens obtained with a Tru-cut needle were compared with those obtained with an Abrams pleural biopsy punch from 36 patients in Zimbabwe judged to have an effusion of at least 1.5 litres; one patient had two biopsies. Both instruments were used on each patient, the Abrams punch being followed by the Tru-cut needle. There were no serious complications. The diagnoses determined by biopsy were: tuberculosis (11); carcinoma (12); chronic inflammation (9); and pleural fibrosis (4); one biopsy showed nothing abnormal. In 23 (62%) patients both biopsy needles produced adequate diagnostic material; in eight the Tru-cut needle alone produced diagnostic material and in six the Abrams punch alone. Thus diagnostic material was obtained in 31 patients from the Tru-cut needle and in 29 from the Abrams punch. The Tru-cut needle was useful and safe for pleural biopsy in this series and appeared to be particularly useful when the pleura was thickened.
