Robotic primary bariatric surgery

In the last two decades, significant growth in the field of robotic bariatric surgery has been noted. Major advantage provided by robotic platform is its three-dimensional, high definition vision, improved degrees of freedom and better precision by taking care of physiological tremors. In improves surgical ergonomics by nullifying excessive torque placed on ports due to thick abdominal wall and thus reduces port site trauma. However, robotic bariatric surgery is perceived to be associated with increased operative time as well as cost. The benefits provided to the patient are also debatable when compared to laparoscopy. Also, there is a learning curve to robotic surgery, which requires team training. In this manuscript, we will discuss the detailed techniques of the commonly performed robotic bariatric procedures. In laparoscopic bariatric surgery anastomosis is usually stapled while it is usually performed in hand sewn fashion when using robotic platform. That leads to difference in operative metrics and postoperative results. We will also discuss the published evidence to support or refute the role of robotic surgery in each of these primary bariatric procedures. With advancements and new platforms being introduced in the field of robotic surgery, there is likely to be a rapid increase in access to this technology.
