Perioperative efficacy of robotic versus open approach for pancreaticoduodenectomy: a Meta-analysis

Pancreatoduodenectomy (PD) is a very challenging operation in pancreatic surgery. Robotic surgery system has obvious advantages in precise operation. In specific patients, minimally invasive (laparoscopic and robotic surgery system) PD is less invasive than conventional open PD, showing good safety and feasibility. There are some differences between robotic surgery system and laparoscopic system in surgical field of vision, surgical operation and anastomosis mode. The authors review the relevant studies and conduct a Meta‑analysis to evaluate the perioperative efficacy of robotic versus open approach for PD.
