Dr. Konstantinidis was the first surgeon in Greece and Southeast Europe to perform robotic surgery in 2006. At the same time, he was a pioneer and opened up the way when, at the invitation of Intuitive Surgical, he performed the world's first single-incision robotic surgery, which was later followed by many more firsts in the field of robotic surgery. After 15 years as a robotic surgeon, he has performed more than 3.500 operations. Add to this another 16.500 laparoscopic surgeries and his experience in minimally invasive surgery exceeds the landmark of 20.000 operations. In his 30-year career in Greece, the prominent robotic-assisted general surgeon at the Athens Medical Center has been a mentor of hundreds of Greek and foreign surgeons, who follow in his footsteps with their achievements in the hospitals of Europe and the US. Intuitive Surgical awarded this important distinction to Dr. Konstantinidis, also considering the fact that the surgical operations he has performed extend to the whole spectrum of general surgery. In particular, his vast experience in surgery covers a number of procedures performed in the esophagus – stomach, pancreas, liver – bile duct, small and large intestine, as well as obesity and metabolic surgery, abdominal wall hernias, sports hernias, adrenal surgery, spleen and internal genital organs surgery and retroperitoneal tumors.
