Spleen-preserving distal pancreatectomy from multi-port to reduced-port surgery approach

Figure 1 Flowchart of the study selection process.

Figure 2 Bar plots. A: Bar plots of the mean body mass index (left figure) and spleen preservation rate (right figure) in each study; B: Bar plots of the mean operating time (left figure) and blood loss (right figure) in each study; C: Bar plots of the mean postoperative pancreatic fistula rate (left figure) and rate of other complications (right figure) in each study; D: Bar plots of the mean hospital stay (left figure) and follow-up duration (right figure) in each study. The green bars indicate multi-port laparoscopic distal pancreatectomy (LDP) studies; blue, reduced-port LDP; orange, reduced-port robotic distal pancreatectomy. Blanks indicate the study did not report this information. BMI: Body mass index; 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; POPF: Postoperative pancreatic fistula.
