[Pleural biopsy: benefits of a new needle (author's transl)].

Authors compare results shown by Abrams needle and a new needle in pleural biopsies. With the new needle, Abrams-derived, out of 102 biopsies, there are 30 percent of unquestionable diagnosis and 10 percent of failure, though handlers were not in training. These results are statistically significant better than those of 244 biopsies with Abrams needle and recorded by the same pathologist (M.J.). They are comparable with those of handlers well trained.
