title: Review of contemporary role of robotics in bariatric surgery.
abstract: With the rise in a number of bariatric procedures, surgeons are facing more complex and technically demanding surgical situations. Robotic digital platforms potentially provide a solution to better address these challenges. This review examines the published literature on the outcomes and complications of bariatric surgery using a robotic platform. Use of robotics to perform adjustable gastric banding, sleeve gastrectomy, roux-en-y gastric bypass (RYGB), biliopancreatic diversion with duodenal switch and revisional bariatric procedures (RBP) is assessed. A search on PubMed was performed for the most relevant articles in robotic bariatric surgery. A total of 23 articles was selected and reviewed in this article. The review showed that the use of robotics led to similar or lower complication rate in bariatric surgery when compared with laparoscopy. Two studies found a significantly lower leak rate for robotic gastric bypass when compared to laparoscopic method. The learning curve for RYGB seems to be shorter for robotic technique. Three studies revealed a significantly shorter operative time, while four studies found a longer operative time for robotic technique of gastric bypass. As for the outcomes of RBP, one study found a lower complication rate in robotic arm versus laparoscopic and open arms. Most authors stated that the use of robotics provides superior visualisation, more degrees of freedom and better ergonomics. The application of robotics in bariatric surgery seems to be a safe and feasible option. Use of robotics may provide specific advantages in some situations, and overcome limitations of laparoscopic surgery. Large and well-designed randomised clinical trials with long follow-up are needed to further define the role of digital platforms in bariatric surgery.
