I, patient D., was in the clinical research center named after him. Loginova in February 2020 in the department of coloproctology, where I had a serious operation that lasted 4 hours. I would like to express my deep gratitude to the excellent, well-coordinated, middle-and senior-level medical team under the leadership of Mikhail A. Danilov. Many thanks to the surgeon, Georgy Germanovich Sahakian, who performed this serious operation on me. I would also like to highlight the nurse Mikhail, certainly in the future a talented surgeon-coloproctologist. May God grant you all health and prosperity to your department and the entire clinic!!
