Objective:
Retrospective assessment of the influence of postoperative pancreatitis in development of pancreatic fistula.
Material And Methods:
The study included 173 patients after pancreatoduodenectomy performed between 2016 and 2019. Postoperative pancreatitis within the 1st postoperative day was verified considering blood amylase > 125 U/L. Patients with postoperative pancreatitis (n=36) were included in the main group, the control group consisted of 137 patients without pancreatitis. Postoperative pancreatic fistula was determined according to the ISGPS 2016 classification. Statistical analysis of the effect of postoperative pancreatitis on development of pancreatic fistula was carried out using relative risk and odds ratio with 95% confidence interval in both groups.
Results:
Postoperative pancreatitis occurred in 36 (20.8%) out of 173 patients after pancreatoduodenectomy. Pancreatic fistula occurred in 18 (50%) cases. Among 137 patients without postoperative pancreatitis, only 18 (13.1%) patients developed severe pancreatic fistula. Relative risk was 3.8 (95% CI 2.22-6.51, p<0.0001), odds ratio - 6.6 (95% CI 2.91-15.01, p<0.0001).
Conclusion:
Postoperative pancreatitis significantly influences development of severe pancreatic fistula.

Chronic Pancreatitis I: Introduction
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...

Acute Pancreatitis I: Introduction
Acute pancreatitis is characterized by rapid inflammation of the pancreas, often caused by factors like gallstone blockage or excessive alcohol consumption. Chronic pancreatitis, on the other hand, is a slow, progressive inflammation that may result from long-term alcohol abuse, obstructions in the pancreatic duct, or genetic factors.
