  1. Values are mean ± standard deviation. p-values were derived from independent Student’s t-tests at baseline. The statistical differences between GD and LCKD groups for histological type were obtained using Fisher’s exact test after crossover analysis.
  2. NET, neuroendocrine tumour; PPPD, pylorus-preserving pancreaticoduodenectomy; DP, distal pancreatectomy; BMI, body mass index; CEA, carcinoembryonic antigen; CA19-9, carbohydrate antigen 19-9; EER, estimated energy requirement; PN, parenteral nutrition.
