Transbronchial lung cryobiopsy by twin bronchoscopes (kissing technique)

To introduce a new & novel method of obtaining big lung tissue samples by transbronchial lung cryobiopsy by twin bronchoscopes (kissing technique) in an advanced interventional pulmonology suite.

In patients of diffuse parenchymal lung diseases, transbronchial lung cryobiopsy were taken using this novel approach using simultaneously two bronchoscopes under C- arm guidance under conscious sedation. First, a standard fibreoptic bronchoscope was inserted intranasally and fixed just above the area to be biopsied, then fogarty's catheter was introduced through FOB's suction channel and protruded it at the biopsy site. Second, another video bronchoscope was introduced orally by the side of FOB and cryobiopsy were taken using cryobiopsy forceps. Immediately, Fogarty's catheter was inflated and sealed the opening from where biopsy was taken to stop the bleeding. Third Video bronchoscope was also used which went up to larynx to take photograph of two bronchoscopes kissing each other and entering the vocal cords only, after which it was withdrawn.

Transbronchial lung cryobiopsy in patients of diffuse parenchymal lung diseases were taken using this novel approach. This new technique called twin bronchoscopy (Kissing technique) has been practiced for the first time, it's a technique about which we want the world to be known.

This new and novel two scope kissing bronchoscopy technique for TBLC under conscious sedation can be an alternative and fruitful method, especially the use of Fogarty's catheter to contain intra-bronchial bleeding. There is no deleterious effect on the patient and the patient can be discharged on the same day.
