Reduced port minimally invasive distal pancreatectomy: single-port laparoscopic versus robotic single-site plus one-port distal pancreatectomy.

Both SPL and RSS + 1 are technically feasible and safe. RSS + 1-DP is superior to SPL-DP in terms of operation time, blood loss, severe complications, and hospital stay. SPL-DP shows advantages in terms of single wound site, less trocar usage, higher rate of spleen preservation, and wider range of operative field.
