To evaluate the diagnostic yield and the quality of biopsy in patients who underwent medical thoracoscopic lung biopsy (MTLB) using stapler device under regional anaesthesia, and neuroleptic analgesia for the evaluation of peripheral mass or diffuse interstitial lung disease.
From 6/2000–3/2004, 23 patients (16 males and 7 females) of mean age 58.5 yrs, (range 28-75 years) underwent MTLB. Biopsy samples were taken with the use of a stapler device. Anaesthesia was achieved with the use of midazolam and fentanyl. Intercostal block was performed in all patients with the use of ropivacain.
Mean diameter of the biopsy specimens from stapler device was 3.2x1.7x0.9cm (mean volume: 3.61ccm). All lung biopsies were conclusive and diagnosis was established. Mean duration of the procedure was 30 min (15–35 min). There were no intraoperative or postoperative deaths or major complications. Successful analgesia was achieved in all patients.
Stapler specimens received by MTLB have a high diagnostic accuracy in patients with peripheral tumors and diffuse interstitial lung disease. MTLB has also been shown to be a quick and safe diagnostic procedure for the evaluation of these cases.
This method is highly diagnostic and does not seem to have significant complications.
