Preoperative characteristics and characteristics of surgery (mean ± SD or median values with IQR or percentages as appropriate, P values).

¹Preoperative patient year was defined as the time from onset of chronic pain requiring first admission.

²During one year before surgery.

³Median comprehensive complications index for complicated cases (short pancreaticojejunostomy n = 3, long pancreaticojejunostomy n = 8).

S-PJ: Short pancreaticojejunostomy; L-PJ: Long pancreaticojejunostomy; IQR: Interquartile range; CP: Chronic pancreatitis; PY: Patient year; PD: Pancreatic duct; DM: Diabetes mellitus; BMI: Body mass index; PEI: Pancreatic exocrine insufficiency; IO: Intraoperative; PRC: Packed red cells; CCI: Comprehensive complications index.
