Background: Robotic surgical systems provide motion stabilization by improved dexterity of wristed instruments, and magnified three-dimensional (3D) imaging. However, the effectiveness of this method remains uncertain in the era of distal pancreatectomy.
Aim: This study compared the perioperative and early oncologic outcomes between robot-assisted laparoscopic distal pancreatectomy (RA-LDP) and conventional laparoscopic distal pancreatectomy (LDP) performed by single surgeon.
Methods: The clinicopathologic features of 85 consecutive patients who underwent minimally-invasive distal pancreatectomy from October 2015 to August 2016 were retrospectively reviewed.
Results: Twenty six patients underwent RA-LDP and 59 had LDP. The median operative time was longer and procedures' cost was higher in RA-LDP group. There was increased frequency of spleen-preserving pancreatectomies in RA-LDP. There were no significant differences in operative blood loss, postoperative morbidity including pancreatic fistula, and postoperative hospital stay. There were no postoperative mortality. Compared with LDP for pancreatic cancer, RA-LDP had higher number of harvested lymph nodes and higher rate of R0 resection.
Conclusion: RA-LDP had similar perioperative outcomes compared with LDP. However, it was associated with high rate of spleen preservation. The oncological outcomes were superior for RA-LDP in terms of improved lymph node clearance and the rate of margin negative. RA-LDP can be safely adopted for left-sided pancreatic tumors by appropriate patient selection.
