STUDY OBJECTIVE: To compare between Abrams and Cope needles pleural biopsy, as regard their diagnostic yield and complications in pleural effusions. STUDY DESIGN: Retrospective chart analysis SETTING: 140 bed community chest hospital, ministry of health, affiliated with teaching hospitals in Riyadh area. MATERIALS AND METHODS: 57 patients (44 males and 13 females), with a mean age of 37.9 years (range, 17-80 years), who were admitted through July 1994 to June 1995, for management of pleural effusion. INTERVENTION: Pleural biopsy was performed for all patients, using either cope needle (group 1: 22 patients), or Abrams needle (group 2: 35 patients). MEASUREMENT: We recorded the type of pleural biopsy needle, final diagnosis and complications. RESULTS: The overall diagnostic sensitivity in pleural effusions for Cope needle was 82% (18/22), compared to 54% (19/35) for Abrams needle. The diagnostic sensitivity in TB pleurisy for Cope needle was 85% (17/20), compared to 57.5 (19/33)% for Abrams needle ( P = 0.08). The incidence of pneumothorax was 18% (4/22) with cope needle, compared to 8% (3/35) with Abrams needle ( P = 0.5) no other complications occurred with both needles. CONCLUSION: Cope needle demonstrates a diagnostic sensitivity equal to that of Abrams needle, without increase in the incidence of pneumothorax.
