Forceps Versus Cryobiopsy in Undiagnosed Exudative Pleural Effusion Using Rigid Thoracoscopy
Sponsor: Ahmed Zakaria Elsaeed
Summary
This study compared two ways of taking tissue samples from the lining of the lung (pleura) during rigid thoracoscopy in adults with pleural effusion of unknown cause: conventional forceps biopsy and cryobiopsy (freezing the tissue so a larger sample can be taken). Both methods were used in the same patients during the same procedure. The study looked at how often each method gave a diagnosis, the size and quality of the samples, and side effects such as bleeding and pain.

Interventions
Pleural Cryobiopsy
Four cryobiopsies were taken from the pleura during rigid thoracoscopy using a flexible cryoprobe (ERBOKRYO CA, CO2 gas, freezing time 30 seconds).
Pleural Forceps Biopsy
Four conventional forceps biopsies were taken from the pleura during the same rigid thoracoscopy session.
