Implementation of robot-assisted Ivor Lewis procedure: Robotic hand-sewn, linear or circular technique?

Background: Robot-assisted surgery for esophageal cancer is increasingly applied. Despite this upsurge, the preferential technique to create a robot-assisted intrathoracic anastomosis has not been established. Data sources: Bibliographic databases were searched to identify studies that performed a robot-assisted Ivor Lewis esophagectomy and described the technical details of the anastomotic technique. Out of 1701 articles, 16 studies were included for systematic review. Conclusions: This review shows that all technique used to create a thoracoscopic anastomosis can be adopted to robotic surgery. Techniques can be divided into three categories: robotic hand-sewn, circular stapling or linear stapling and robotic hand-sewn closure of the stapler defect. With limited robotic experience, circular stapling might be the preferred technique, however requires a well-trained bedside assistant. The linear stapling technique or hand-sewn technique are more challenging but enable experienced robotic surgeons to perform a controlled anastomosis without bedside support
