  • The position of the pancreatic duct in pancreatic section affects the occurrence of postoperative pancreatic fistula

    Objective To investigate the effect of the position of pancreatic duct in pancreatic section on postoperative pancreatic fistula. Methods The clinical data of patients undergoing pancreaticoduodenectomy admitted to the pancreatic surgery department of our hospital from September 2018 to August 2020 were retrospectively collected. The consistency between intraoperative pancreatic section data and preoperative CT cross-sectional images of pancreatic duct was compared, and the occurrence of postoperative pancreatic fistula was analyzed by univariate analysis and multivariate logistic regression model analysis, to determine whether the position of pancreatic duct on pancreatic section during pancreaticojejunostomy had an impact on the occurrence of postoperative pancreatic fistula. Results A total of 373 patients were included in this study. In 44 cases, the ratio of the thickness of the short distance from the center of the pancreatic duct to the edge of the pancreas at the pancreatic section was 0.41±0.09, and the imaging measurement value was 0.40±0.10. The interclass correlation coefficient detection value of the two measurement methods was 0.916 (>0.75), P<0.001, this had high consistency. Patients had a high BMI [OR=1.276, 95%CI (1.154, 1.411), P<0.000 1] and soft pancreatic texture [OR=2.771, 95%CI (1.558, 4.927), P=0.001] were independent risk factors for postoperative pancreatic fistula, while the risk of postoperative pancreatic fistula decreased with the increased proportion of pancreatic duct thickness from center to edge [OR=0.875, 95%CI (0.840, 0.911), P<0.000 1]. Conclusions Patients with high BMI and soft pancreas are independent risk factors for postoperative pancreatic fistula, and the risk of postoperative pancreatic fistula is reduced when the center of pancreatic duct is far from the edge of pancreas. The ratio of short distance from the center of pancreatic duct to the edge of pancreas to the total thickness of pancreas measured by preoperative imaging can be used to evaluate the risk of postoperative pancreatic fistula.
