Characteristics of pancreatic anatomical parameters and POPF. a Summary of PLH values in patients with and without POPF after laparoscopic and open gastrectomy using a one-dimensional scatter plot and a comparison using the Mann–Whitney U test. b Summary of P-A length values in patients with and without POPF laparoscopic and open gastrectomy. c Summary of PLD values in patients with and without POPF laparoscopic and open gastrectomy. d Receiver operating characteristics curves of the PLH to predict POPF after laparoscopic gastrectomy. PLH, the maximum vertical length between the upper border of pancreas and the root of left gastric artery; P-A, pancreas-aorta; PLD, the maximum horizontal length between the upper border of pancreas and the root of left gastric artery; POPF, pancreatic fistula
