FIELD: medicine.
SUBSTANCE: invention refers to medicine, namely to experimental surgery. It involves ultrasound aided transcutaneous puncture above a focal mass with using a needle with a mandrin. The latter is removed when reaching an edge of a parenchymal organ. Through a needle lumen, a laser guide is passed to a distal edge of the needle. The parenchyma is exposed at wave length 1064 nm and power 10 Wt in a constant mode, with advancing the needle through the parenchyma to borders of the focal mass. The light guide is removed, and the focal mass is punctured.
EFFECT: method provides elimination of haemorrhage and bile flow from a puncture canal, minimally invasive manipulations.
