%X <B>BACKGROUND: </B>Postoperative pancreatic fistula (POPF) is a potentially life-threatening complication after pancreaticoduodenectomy (PD). It is observed when the amylase activity in the drain fluid exceeds three times the normal upper value. Grades B and C of POPF are considered as clinically relevant. Fistula might originate due to failure of healing of a pancreatic anastomosis or from raw pancreatic surface.<BR><B>METHODS: </B>18 retrospective and prospective studies published between 2015 and 2020 were included in this meta-analysis. Total number of patients was 5836. To investigate potential risk factors associated with the occurrence of POPF, odds ratios (OR) with 95% confidence intervals (CI) were calculated. To compare discontinuous data, mean differences (MD) were calculated.<BR><B>RESULTS: </B>13 factors were divided into preoperative and intraoperative groups. Male sex, higher BMI, soft pancreatic texture and small pancreatic duct were considered as significant risk factors while vascular resection lowered the risk of development pancreatic fistula.<BR><B>CONCLUSIONS: </B>It is considered that the development of POPF is associated with intrapancreatic fat. More severe infiltration with fat tissue is responsible for soft texture of the gland, while higher BMI is one of the risk factors of increased pancreatic fat. On the contrary, diabetes is associated with fibrotic pancreas which could lower the risk of developing POPF.
