 This study examined two groups of patients who underwent pancreatic oedental resection surgery. One group received preoperative assessment of their risk for developing postoperative pancreatic fistula and sarcopenia, while the other did not receive this assessment. The results showed that the rate of occurrence of postoperative complications was significantly higher in the comparison group compared to the main group. Additionally, the main group had a much lower rate of occurrence of grade B pancreatic fistula, compared to the comparison group. This suggests that the use of preoperative assessments can help reduce the occurrence of postoperative complications such as pancreatic fistula. This article was authored by V. Chak, L. Pariva, V.
