I want to express my gratitude as the attending physician to Artykova Guzel Bahadurovna, as well as her assistant Yulia Igorevna and all the nurses of the post and procedural department of gastroenterology on the 3rd floor for their professionalism, sensitive attitude to patients. And separately, I also want to mention the endoscopist Kiryanov Vitaly Alexandrovich. This is the only specialist who knows how to perform a colonoscopy painlessly without any anesthesia. Hands, as they say, from God. Now only to him. I have never met more friendly staff in Moscow clinics.
