Hi all, I am a patient diagnosed with Crohn's disease and luckily operated by Dr. Markides at Aretaeio hospital. Two months almost passed after my two operations and I feel strong, healthy and able to start exercising again. Thus, I decided to write this brief review to publicity thanks Dr. Markides for the excellent work he did to me. I found Dr. Markidis online, more specifically from his personal website. His resume, academic records, and experience have impressed me. After gathering, positive references from people knowing him I decided to visit his office. During the first meeting, he explained me all the possible aspects of the pain cause while the previous doctors (in both private and public sectors) I visited failed to comply and understand the potential source of pain. Dr. Markides decided to give me for 6-7 weeks medication before his operation since my previous doctor operated me and did nothing because he did not understand the issue. Six weeks after the first failed operation from the previous doctor, Dr. Markides was able to put me in surgery with his laparoscopic tools. The operation lasted for 7 hours, removing approximately 30 cm mass of infected bowels (connection between colon and small intestine). Laparoscopic surgery was challenging, due to the limited degrees of freedom offered by the tools, but he successfully performed it with his skills, so his patient can recover fast and feel less pain. During my recovery, I suffered from fever that lasted around 10 hours per day. Dr. Markides treated the fever methodically by doing different medical tests before offering me any medication during my stay in Aretaeio. As soon as he found the cause of the fever, it vanished totally in two days. I am strongly suggesting taking his opinion, he is an excellent scientist with great personality respecting and supporting his patients.
