Clinical Trial Summary

This is a prospective study on the safety and effectiveness of radiofrequency ablation in patients with desmoid tumors. In the study group, all patients after radiofrequency ablation of the tumor after 1 month will be evaluated using MRI and CT studies and, if solid components of the tumor are detected, repeated surgical treatment is performed followed by active monitoring after 1 month. In the absence of a solid component, the effect is estimated by the volume of the necrotic process and monitored in dynamics every 3 months.

Intervention

Procedure:
• radiofrequency ablation
Anesthesia: Local (Novocaine, Lidocaine, Bupivacaine) Access: transcutaneous Navigation under CT control Cannulas are used: 22G 100 and 150 mm, the size of the electrode corresponds to the size of the cannula The starting power is 20W followed by steps of 10W every 2 minutes until the maximum power is reached, the maximum power is 60W. In order to prevent infectious complications, two-day antibiotic prophylaxis of Cefazolin (1g) is carried out 3 times a day In order to prevent skin burns with superficially located DFS, the skin is cooled during the procedure.
