Objective To explore the risk factors of chronic postoperative inguinal pain (CPIP) after transabdominal preperitoneal hernia repair (TAPP), establish and verify the risk prediction model, and then evaluate the prediction effectiveness of the model. Methods The clinical data of 362 patients who received TAPP surgery was retrospectively analyzed and divided into model group (n=300) and validation group (n=62). The risk factors of CPIP in the model group were screened by univariate analysis and multivariate logistic regression analysis, and the risk prediction model was established and tested. Results The incidence of CPIP at 6 months after operation was 27.9% (101/362). Univariate analysis showed that gender (χ2= 12.055, P=0.001), age (t=–4.566, P<0.01), preoperative pain (χ2=44.686, P<0.01) and early pain at 1 week after operation (χ2=150.795, P<0.01) were related to CPIP. Multivariate logistic regression analysis showed that gender, age, preoperative pain, early pain at 1 week after operation, and history of lower abdominal surgery were independent risk predictors of CPIP. The area under curve (AUC) of the receiver operating characteristic (ROC) of the risk prediction model was calculated to be 0.933 [95%CI (0.898, 0.967)], and the optimal cut-off value was 0.129, while corresponding specificity and sensitivity were 87.6% and 91.5% respectively. The prediction accuracy, specificity and sensitivity of the model were 91.9% (57/62), 90.7% and 94.7%, respectively when the validation group data were substituted into the prediction model. Conclusion Female, age≤64 years old, preoperative pain, early pain at 1 week after operation and without history of lower abdominal surgery are independent risk factors for the incidence of CPIP after TAPP, and the risk prediction model established on this basis has good predictive efficacy, which can further guide the clinical practice.
Objective To explore the application effect of PDCA cycle management on reducing the unplanned overnight recovery rate in patients undergoing transabdominal preperitoneal inguinal hernia repair (TAPP) under the same-day surgery model. Methods The unplanned overnight recovery rate in patients who underwent TAPP at West China Tianfu Hospital of Sichuan University between January and October 2023 (pre-improvement phase) was analyzed. A quality control group was established, and PDCA cycle management was employed to define control objectives and implement strategies to reduce the unplanned overnight recovery rate. The unplanned overnight recovery rate in patients who underwent TAPP between November 2023 and April 2024 (post-improvement phase) was compared with that in the pre-improvement phase. Results After the implementation of PDCA cycle management, the unplanned overnight recovery rate in patients undergoing TAPP under the same-day surgery reduced from 23.87% (37/155) in the pre-improvement phase to 9.05% (19/210) in the post-improvement phase, with a statistically significant difference (P<0.05). Conclusion The application of PDCA cycle in the process management of TAPP under the same-day surgery model significantly reduces the unplanned overnight recovery rate in patients.
