Objective To explore the influencing factors of textbook outcomes (TO) after radical resection for hepatic alveolar echinococcosis (HAE). Methods Clinical data from 427 patients diagnosed with HAE at the Ganzi Branch of West China Hospital, Sichuan University, between 2015 and 2022, were retrospectively collected. The least absolute shrinkage and selection operator regression (LASSO) was first used to screen potential influencing factors for achieving TO (predictive model A). Univariate and multivariate logistic regression analysis were then used to explore the influencing factors of TO (predictive model B). A Nomogram was further constructed and validated. Results A total of 427 patients who successfully underwent radical liver resection were included, of which 174 patients (40.7%) achieved TO. Compared to the non-TO group, patients in the TO group had higher proportions of WHO PNM stage of P 1+2 [62.6% (109/174) vs 42.3% (140/253)], N0 [77.0% (134/174) vs 63.6% (161/253)], lesion diameter≤10 cm [77.0% (134/174) vs 64.8% (164/253)], albumin-bilirubin index (ALBI) ≤–2.6 [70.1% (122/174) vs 59.3% (150/253)], and minor liver resection [71.8% (125/174) vs 50.2% (127/253)], higher prealbumin (181 mg/L vs 169 mg/L) and albumin (39 g/L vs 38 g/L) levels, shorter postoperative hospital stay (15 d vs 19 d), and lower hospitalization costs (51 727 RMB vs 62 715 RMB), P<0.05. LASSO regression analysis indicated that P stage, lesion diameter, ALBI, and liver resection method were potential influencing factors for achieving TO after HAE surgery (model A), P<0.05. The TO rate for P 1+2 stage was higher than that of P 3+4 stage, the TO rate for lesion diameter ≤ 10 cm was higher than that of lesion diameter >10 cm, the TO rate for ALBI ≤–2.6 was higher than that of ALBI >–2.6, and the TO rate for minor liver resection was higher than of major liver resection. Multivariate logistic regression analysis showed that P stage (OR=1.800, P=0.025) and liver resection method (OR=1.974, P<0.001) were influencing factors for achieving TO (model B). The TO rates for P1+2 stage and minor liver resection were higher. Predictive model A demonstrated higher accuracy and stability compared to predictive model B (AUC: 0.754 vs 0.712, C-index: 0.756 vs 0.707). Conclusions Among patients undergoing radical resection for HAE, less than half achieved TO. Striving to achieve TO can significantly shorten the length of hospital stay and effectively reduce medical costs. The TO predictive model based on P stage, lesion diameter, ALBI, and liver resection method is superior to the model based solely on P stage and liver resection method.
