What is Cryosurgery?

Cryosurgery is an advanced interventional pulmonology procedure that uses the cryoprobe. The cryoprobe is an advanced instrument that can freeze the target tissue to a very low temperature. This frozen tissue can then be sampled or removed easily.

What is Cryobiopsy?

Cryobiopsy is very useful for the sampling of lung tissue (biopsy) or complete removal of tumor mass obstructing the airway. It is a minimally invasive technique and helps in obtaining bigger samples thus giving higher accuracy and avoiding repeat procedures.
In Cryobiopsy, a probe is deployed through the bronchoscope and placed near the target tissue. The probe is cooled for a few seconds, freezing and causing the lung tissue around it to stick to the probe. The scope and probe are removed, and bleeding is controlled using a balloon occlusion catheter. Navigation to the target tissue is assisted by Fluoroscopy or Radial-EBUS. The procedure is mostly performed under general anesthesia and the patient can go home the same day or the next morning after overnight observation.
Cryobiopsy has been proven to be a useful tool for the diagnosis of lung cancer and interstitial lung diseases. Unlike traditional biopsy which involves samples less than 2mm, a cryoprobe can obtain lung tissue more than 1cm and in its intact form without any crush artefacts. Also, it has less risk involved when compared to Surgical Lung Biopsy (SLB). With Radial-EBUS and Fluoroscopy, it has a comparable yield to CT-guided trans-thoracic biopsy without the risk of pneumothorax. When in expert hands,Cryobiopsy has no or minimal complications.
