FIELD: medicine, pediatric surgery and herniology.
SUBSTANCE: during the operation, circular non-traumatic isolation of intratumoral blood vessels is performed in the direction from the aorta to the periphery using an ultrasonic destructor while preserving the adventitia. Precision is ensured by the combined use of the "cold scissors" technique and an operating microscope with simultaneous fragmentation of the tumor. Then the fragmented tumor is dissected.
EFFECT: method makes it possible to increase resection radicalness, improve clinical results and reduce the frequency of intraoperative complications due to precise mobilization of the great vessels and their branches from the tumor.
