Patient-centered bariatric surgery care at Medipol
Assoc. Prof. Dr. Yaşar Özdenkaya is a senior general surgeon at Medipol Mega University Hospital, with extensive experience in bariatric surgery (gastric sleeve, bypass, mini-gastric bypass), advanced laparoscopic procedures, and robotic surgery.
He has performed thousands of weight-loss operations and is a recognized expert in revisional bariatric surgery for patients who have regained weight or experienced complications. Beyond bariatrics, he handles complex hernia repair, gallbladder and biliary surgery, and is part of Medipol's organ transplantation team.
