¹Significantly different in the original study.

The number of trocars and age are presented as mean ± SD; Sex is reported as number of patients. Propensity score matched between single-port laparoscopic distal pancreatectomy (LDP) and multi-port LDP cohorts. “-” indicates data not available. 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.
