Construction of a risk model for complications after endoscopic thyroidectomy through gasless unilateral axillary approach for thyroid tumors
To investigate the influencing factors for postoperative complications following endoscopic thyroidectomy through gasless unilateral axillary approach (ETGUA) and construct a corresponding risk prediction model.
Methods
2
A retrospective analysis was conducted on the clinical data of 220 patients with thyroid tumors who underwent ETGUA in our hospital from January 2023 to March 2025. The patients were divided into the non-complication group (
n
=189) and the complication group (
n
=31) based on whether postoperative complications occurred. The univariate analysis and multivariate
Logistic
regression analysis were conducted to identify the influencing factors for complications after ETGUA treatment in patients with thyroid tumors, and then a
Logistic
regression prediction model was constructed and visualized with a nomogram. The predictive efficacy,calibration degree and clinical practicability of the model were evaluated using the
receiver operating characteristic
(
ROC
) curve,

goodness-of-fit test,and
decision curve analysis
(
DCA
).
Results
2
The results of multivariate
Logistic
regression analysis showed that low levels of preoperative parathyroid hormone (PTH) and PTH on the first day after surgery were both independent risk factors for complications after ETGUA in patients with thyroid tumors (
P
<
0.05). Based on these factors,a
Logistic
regression risk prediction model was constructed [Logit(
P
)=3.835-0.044×preoperative PTH-0.055×PTH on the first day after surgery],and a nomogram was drawn. The
ROC
curve analysis showed that the
area under the curve
(
AUC
) of this model for predicting complications was 0.779 (95%
CI
:0.687 to 0.870),with a sensitivity of 71.00%,a specificity of 81.00%,and a
Youden
index of 0.520. The

Lemeshow
goodness-of-fit test showed that the predicted probability of the model was in good agreement with the actual probability (
χ
2
=4.347,degrees of freedom=8,
P
=0.825).
DCA
showed that the net benefit of the model was significantly higher within the threshold probability range of 0.05 to 0.40.
Conclusion
2
Lower preoperative PTH and PTH on the first day after surgery are influencing factors for postoperative complications in thyroid tumors patients treated with ETGUA. The risk prediction model constructed based on the two factors has a relatively high predictive value, which can provide certain references for clinical prevention and treatment.
