A cryobiopsy diagnostic device for better accuracy in identifying lung cancer was dedicated at the Government Rajaji Hospital (GRH) here on Monday. Hospital dean Dr K Vanitha, who dedicated the Rs 20 lakh device said it facilitates better accuracy in detecting the type of cancer in the lungs, compared to the traditional bronchoscopy.
While in bronchoscopy the suspected tissue is cut and taken from the lungs and the accuracy in detection is only 75%, in cryobiposy, the chances are 97%.
Elaborating on the device, she said a cryo catheter is sent in through a bronchoscope. “Carbondioxide gas is sent through the tip of the cryo catheter to reduce the temperature of the tissues to minus 5 to minus 14 degree Celsius. The iced tissues for 0.5cm to 1cm is then easily taken out using the cryobiopsy as the tissue sticks to the device once it touches it,” she said. Vanitha added that this procedure does not miss out on non-cancerous tissues, does not affect other tissues, causes very minimal bleeding and is less painful.
The dean said that the GRH is the first among government hospitals in the state to get a cryobiopsy instrument. The device was purchased under the self-sufficiency scheme of the Madurai district collector. – TOI
