FIELD: medicine.
SUBSTANCE: invention refers to medicine and can be used to predict the risk of developing postoperative pancreatic fistula (PPF) following pancreaticoduodenal resection. That is ensured by estimating the average pancreatic parenchyma density in Hounsfield's units (HU) measured in future pancreaticojeanastomosis on preoperative native computed tomographic images by histogram analysis. If the parenchyma density is>> +30 HU, score is 0 points, ≤ + 30 HU - 2 points. If the main pancreatic duct diameter is ≥ 5 mm, 0 points, 4 mm - 1 point, 3 mm - 2 points, ≤ 2 mm - 3 points. If the volume of intraoperative blood loss ≤ 500 ml is evaluated as 0 points, 501-700 ml - 1 point, 701-1000 ml - 2 points, > 1000 ml - 3 points. Obtained points are summed up. If the total score is ≥ 4, the risk of postoperative pancreatic fistula development is considered to be high. If the total score is < 4, the risk of developing PPF is considered to be low.
EFFECT: invention enables predicting the risk of developing postoperative pancreatic fistula in the above patients.
