Effect of robotic versus open pancreaticoduodenectomy on postoperative length of hospital stay and complications for pancreatic head or periampullary tumours: a multicentre, open-label randomised controlled trial.

Background: The flexibility of the robotic system in resection and reconstruction provides potential benefits in pancreaticoduodenectomy. Increasingly, robotic pancreaticoduodenectomy (RPD) has been reported with favourable outcomes, but high-level evidence is still scarce. We aimed to compare the short-term postoperative outcomes of RPD with those of open pancreaticoduodenectomy (OPD), and hypothesised that postoperative length of hospital stay would be shorter after RPD than after OPD.
