[Contrast-enhanced computed tomography in evaluation of pancreatic stump volume in pancreaticoduodenectomy].

OBJECTIVE
To analyze the role of contrast-enhanced computed tomography in evaluation of pancreatic stump volume for prediction of significant pancreatic fistula.


MATERIAL AND METHODS
A retrospective analysis enrolled 99 patients. Patients were divided into 2 groups depending on the course of postoperative period and development of clinically significant pancreatic fistula. The first group included 24 patients (25%) with clinically significant postoperative pancreatic fistula. The second group included 75 patients (75%) without postoperative complications. Pancreatic structure, pancreatic parenchyma thickness (mm), pancreatic duct diameter (mm) and volume of pancreatic stump (cm3) were preoperatively analyzed considering contrast-enhanced computed tomography data.


RESULTS
The risk of postoperative pancreatic fistula is 10 times higher in case of soft structure of the pancreas, 1,7 times higher in decrease of pancreatic duct diameter, 9,3 times higher in increased volume of residual pancreatic parenchyma, 8.6 times higher in increase of pancreatic parenchyma thickness.


CONCLUSION
Contrast-enhanced computed tomography is valuable for preoperative evaluation of the volume of residual pancreatic parenchyma and identification of patients with high risk of postoperative pancreatic fistula.
