Prof. Mahir Özmen is one of the highly acknowledged general surgeons of Turkey alongside his academic accomplishments that makes him a recognized international surgeon. He has published over 200 research papers with 4000 citations that carry himself to a very high H-index which is an international measure of academic performance. He holds many international titles including the American Society of Metabolic and Bariatric Surgery (ASBMS), Fellow of Royal College of Surgeons Glasgow FRCSİ, Fellow of European Board of Surgery FEBS, etc. and acts as an international teaching and governing surgeon who trains surgeons from all around the world.
Davinci XI is one of the latest technology tools for gastrointestinal (GI) cancers, for both upper GI and colorectal tumor surgeries. It is a kind of laparoscopic surgery but rather than using laparoscopic instruments, surgeon uses many arms of the robot from a console. As compared to open or laparoscopic surgery, robotic surgery is slightly more expensive but definitely has clear superiorities. These advantages are very obvious when compared to open surgery, such as small incision and a shorter recovery time just like any other laparoscopic surgery.
Some may argue that these differences become minor when robotic surgery and laparoscopy is compared, but the common sense of the world disapproves with the argument. The magnification capability of the robot is 16-20 times higher compared to open and laparoscopic methods that enable much better dissection.
More importantly, it provides better access and higher maneuverability since the human hand is capable to rotate around 320 degrees whereas with robot 360 + 180 degrees can be achieved. This creates undoubted leverage for the surgeon and provides him/her the capability to access very narrow places, deal with tumors in narrow spaces, and also place sutures anywhere inside the abdomen.
Besides these, the robot also lets the surgeon see the nerves better and reduce the risk of harming erection or sexual functions in male patients.
As a robotic surgeon performing since 2013, Prof. Mahir Özmen defines robotic surgery as “definitely the best option” for patients with rectal cancer, especially with tumors located on the lower-left side of their colon. He also underlines the convenience to have the robot on his side to be used in need, when dealing with upper GI. He mentions that there may be occasions to utilize the advantages of robotic surgery even for tumors on the stomach and esophagus.
