PURPOSE: Transbronchial needle aspiration (TBNA) for histological or for cytological specimens is limited cause of the needle size. In mediastinal masses the diagnostic value is reduced. We tried to obtain histological specimens from mediastinal masses using a 1.2-mm miniforceps under EBUS control and compared the forceps biopsy to TBNA.
METHODS: Patients with mediastinal masse > 3 cm were included. The LN was first punctured by a 22 gauge needle under radial EBUS control, then conventional 19 gauge needle; then the miniforceps again under radial EBUS control.
RESULTS: 52 consecutive patients (30 male, 22 female, mean age 38, 3y) were examined. Usable materials were obtained in all patients with all techniques. A specific diagnosis was made in 36 % using the 22 gauge needle, 54 % by the 19 gauge needle and 88 % by the miniforceps (table 1). There was no difference in the duration of the 3 procedures. No complications were seen.
CONCLUSION: We conclude that MFB under EBUS control is a helpful adjunct to TBNA for histological or cytological specimen sampling of mediastinal masses without additional complications.
CLINICAL IMPLICATIONS: Also bigger mediastinal lesions are able to diagnose with the help of a mini-forceps.
