METHOD FOR PREDICTING THE DEVELOPMENT OF POSTOPERATIVE PANCREATIC FISTULA WHEN PLANNING RESECTION INTERVENTIONS ON THE PANCREAS Russian patent published in 2023 - IPC A61B8/12 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, namely to surgery and ultrasound diagnostics, and can be used to predict the risk of developing postoperative pancreatic fistula when planning resection interventions on the pancreas. Endoscopic ultrasound examination of the abdominal organs and elastography is performed. After determining the choice of the area of interest, which is the area of the proposed resection of the pancreas, the position of the ultrasonic sensor is fixed for 10 seconds, the measurement is carried out in the elastometry mode in each area of interest, namely, in the area of the pancreatic parenchyma in the area of the proposed resection and the area of parapancreatic fat. Then the coefficient of deformation is measured, which is equal to the ratio of the rigidity of the parapancreatic tissue to the rigidity of the pancreatic parenchyma in the area of the proposed resection. If the value of the strain coefficient is less than 23.3, a high risk of developing postoperative pancreatic fistula is predicted, and if the value of the strain coefficient is greater than or equal to 23.3, a low risk of developing postoperative pancreatic fistula is predicted.

EFFECT: method allows to reduce the risk of developing pancreatic fistula in the postoperative period by correcting the tactics of perioperative management of patients by assessing the totality of the most significant indicators.
