I would like to thank from the bottom of my heart the wonderful doctors of the Department of Endoscopic Surgery: Kirill V. Shishin, Head of the Department, and Ivan A. Pavlov, Doctor. They did what the doctors in my city refused to do. I was told that in the ninth decade it is impossible. But for Shishin and Pavlov, it turned out to be quite possible. They carried out an operation, as a result of which no trace of the problem remained.
Thank you! May God grant you health and strength!
