¹Significantly different in the original study.

Body mass index, operating time (min), blood loss (mL), tumor size (cm), length of hospital stay (d), and length of follow-up (mo) are reported as mean ± SD; spleen preservation rate, postoperative pancreatic fistula rate, and complication rate are reported as percentages. 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; BMI: Body mass index; OP: Operating; POPF: Postoperative pancreatic fistula; SP: Spleen preservation.
