AIM: Pancreatic fistula (PF) and anastomotic leakage are significant complications of the pancreaticoduodenectomy (PD). The PF is considered as the root cause of other major complications of PD. The aim of the study was to investigate the risk factors underlying PF that occurred after PD and the effects of the PF on postoperative morbidity.
MATERIAL AND METHODS: In this study, fifty patients who underwent classic PD were evaluated, retrospectively. Patients were divided into two groups as patients with PF and patients without PF. The following demographical, clinical and operative parameters were collected to evaluate the PF; age, gender, preoperative biochemical parameters, resection type, duration of the operation, patient’s comorbidities, amount of perioperative transfusion, localization of the tumour, texture of the residual pancreas, type of the anastomosis and the diameter of the pancreatic duct.
RESULTS: A statistically significant relation was found between the texture of the remnant pancreatic parenchyma and PF (p<0.001). A significant relation was determined between PF and preoperative ALP, GGT, AST, ALT, hemoglobin levels and length of the hospitalization (p<0.05). In this study, we found that mortality, abdominal bleeding, bile leakage, intra-abdominal abscess were associated with reoperation and prolonged hospitalization.
CONCLUSION: The lack of internationally accepted definition of a fistula is an important issue. Preoperative high ALP, ALT, AST, GGT values, low hemoglobin values and soft texture of remnant pancreatic tissue were found to be related with PF that occurs after PD. Residual pancreatic tissue has been shown as an independent risk factor.
