Electrosurgical resection using devices such as an electric knife or diathermy blade is currently a widely used technique in neurosurgery. When tissue is burned, tissue molecules are dispersed in the form of surgical smoke. In the method developed by researchers at Tampere University, the surgical smoke is fed into a new type of measuring system that can identify malignant tissue and distinguish it from healthy tissue.
An article on using surgical smoke to identify brain tumours was recently published in the Journal of Neurosurgery.
Practice - Section - Analysis - Standard - Tumour
"In current clinical practice, frozen section analysis is the gold standard for intraoperative tumour identification. In that method, a small sample of the tumour is given to a pathologist during surgery," says researcher Ilkka Haapala from Tampere University.
The pathologist undertakes a microscopic analysis of the sample and phones the operating theatre to report the results.
Method - Way - Tissue - Time - Ability
"Our new method offers both a promising way to identify malignant tissue in real time and the ability to study several samples from different points of...
