¹Significantly different in the original study.

Values are reported as mean ± SD. Propensity score matched between single-port laparoscopic distal pancreatectomy (LDP) and multi-port LDP cohorts. MP_LDP: Multi-port laparoscopic distal pancreatectomy; RP_LDP: Reduced-port laparoscopic distal pancreatectomy; RDP_SS+1: Robotic distal pancreatectomy with single-site plus one-port.
