High-risk factors for venous thromboembolism after laparoscopic pancreatic cancer surgery and construction of a nomogram model
To explore the high-risk factors for postoperative venous thromboembolism (VTE) in patients undergoing laparoscopic pancreatic cancer surgery and construct a nomogram prediction model to evaluate its efficacy.
Methods
2
A total of 43 patients who developed VTE after laparoscopic pancreatic cancer surgery in our hospital from January 2023 to December 2024 were selected as the observation group,and 86 patients who underwent laparoscopic pancreatic cancer surgery during the same period without VTE were matched at a 1∶2 ratio as the control group.The cl
inical data of patients in the two groups were retrospectively analyzed.Independent risk factors were screened by multivariate
Logistic
regression analysis,and a nomogram prediction model was constructed by R software.The model efficacy was evaluated by
receiver operating characteristic
(
ROC
) curve,calibration curve,and decision curve.
Results
2
Multivariate
Logistic
regression analysis showed that decreased lymphocyte count(
OR
=238.331,95%
CI
:27.882 to 303.220),elevated tissue factor (
OR
=6.211,95%
CI
:3.252 to 11.865),elevated D-dimer on postoperative day 1 (
OR
=2.744,95%
CI
:1.506 to 5.000),allogeneic vascular replacement (
OR
=2.622,95%
CI
:1.113 to 6.175),and poor differentiation (
OR
=3.007,95%
CI
:1.264 to 7.153) were the independent risk factors for postoperative VTE in patients underwent laparoscopic pancreatic cancer surgery (
P
<
0.05).
ROC
curve analysis showed that the
area under the curve
(
AUC
) of the combined indicators for predicting postoperative VTE was 0.984 (95%
CI
:0.967 to 1.000).The calibration curve was tested by

goodness-of-fit test (
χ
²=3.543,
P
=0.896),indicated that there was no significant difference between the predicted probability of the model and the actual probability of VTE occurrence,with good fitting performance.Decision curve analysis showed that the model had a significant positive net benefit when the risk threshold was greater than 0.03,demonstrating favorable clinical utility.
Conclusion
2
The nomogram model constructed based on decreased lymphocyte count, tissue factor,D-dimer on postoperative day 1,vascular reconstruction method,and degree of differentiation demonstrates high predictive efficacy for postoperative VTE in patients undergoing laparoscopic pancreatic cancer surgery,which can assist in clinical identification of high-risk patients and provide evidence for formulating targeted intervention measures.
