I want to thank the doctors of the Gastroenterological Department of the MCSC named after A. S. Loginov for the excellent operation. The high professionalism of the medical staff, his clear and well-coordinated work made it possible to quickly return to active life. Especially pleasing is the high qualification and youth of the treated staff. The work of the department, despite the large number of patients, occurs with the clarity of a well-established clockwork. Many personal thanks to the head of the Department of endoscopy professor Shishin K. V. and the Attending Physician Kanishchev I. S.
