About

Theodoros Diamantis is a bariatric surgeon and researcher whose work has significantly advanced the application of minimally invasive and robotic techniques in the surgical treatment of morbid obesity. His research has focused primarily on robotic and laparoscopic bariatric procedures, with particular emphasis on sleeve gastrectomy and Roux-en-Y gastric bypass. Diamantis is widely recognized for his pioneering contributions to robotic bariatric surgery, most notably his early adoption and systematic evaluation of robotic sleeve gastrectomy — a topic he explored across multiple landmark studies spanning more than five years of clinical experience. His 2010 paper on initial robotic sleeve gastrectomy experience remains his most influential work, accumulating 74 citations and helping to establish the procedure's feasibility and safety profile. His subsequent research incorporating intra-operative endoscopy into laparoscopic sleeve gastrectomy further refined surgical technique, drawing 21 citations. Diamantis also contributed early evidence supporting fully robotic Roux-en-Y gastric bypass, highlighting the role of robotics in reducing perioperative morbidity. Collectively, his body of work has helped shape modern standards in robotic bariatric surgery and continues to inform both clinical practice and surgical training.
