Deskripsi

Aim. This study was conducted to assess the possibility of ultrasound elastometry using the shear wave method in the preoperative assessment of the stiffness condition of the  pancreatic parenchyma in order to predict the risk of complications and the choice of the method for the formation of pancreatoenteroanastomosis in pancreatoduodenal resection.Materials and methods. The study was performed in 10 patients operated in the volume of pancreatoduodenal resection. All patients  underwent preoperative ultrasound pancreatic elastometry with  transcutaneous shear wave access method. The results were  compared with the intraoperative data obtained by the visual  examination and palpation. Depending on the average "stiffness"  indicators of the parenchyma in comparison with the intraoperative  data, one of two ways of forming the pancreatic intestinal  anastomosis was preferred: either end-to-side or  pancreatoenteroanastomosis with a wide atraumatic peritonization of the pancreas stump cutoff by the jejunum according to the original technique.Results. The inconsistency of class A pancreatoenteroanastomosis was noted in 2 (20%) patients, it was transient, asymptomatic, did  not require additional medical interventions and did not extend the  duration of the postoperative period. There were no inconsistencies  of classes B and C, pancreonecrosis of the stump, repeated surgical  interventions, and lethal outcomes.Conclusion. Ultrasound pancreatic elastometry with the shear wave method can be used in the preoperative assessment of the  "stiffness" of the parenchyma in order to predict the risk of the  complications and the choice of the method for the pancreatoenteroanastomosis formation.
