Predicting of pancreatic fistula after pancreatoduodenectomy

Abstract

OBJECTIVE: Identifying the opportunity of objective prognosis of pancreatic fistula emergence after pancreatoduodenectomy. MATERIAL AND METHODS: In the department of abdominal surgery in 2016-2019, 177 pancreatoduodenectomies for pancreatobiliary tumors were performed. 4 risk factors were identified: type of tumor, preoperative CT with an accumulation coefficient in the pancreas of more than 1, soft pancreas, the number of functioning acinar structures identified during intraoperative histological examination. Statistical data processing and predictive modeling were performed using a binary logistic regression model. RESULTS: Clinically significant pancreatic fistula was developed in 47 (26,6%) patients. Risk indicators for the occurrence of pancreatic fistula depending on the presence or absence of risk factors were obtained. Groups of patients were identified that require various preventive and therapeutic measures aimed to treat postoperative pancreatitis and its consequences. CONCLUSION: Predicting the pancreatic fistula emergence allows to take timely preventive and therapeutic measures, both minimal and aggressive (early extracorporeal detoxification, pancreatectomy), which may lead to complications. Well-reasoned pancreatectomy and extracorporeal detoxification is a surgeon's defense in an insured case or legal conflict.
