目的

评估保留括约肌挂线术联合阿达木单抗(ADA)在儿童克罗恩病肛瘘(PFCD)中的长期疗效,并探索影响疗效的预测指标。

方法

回顾性分析2021年1月1日至2024年12月31日符合纳入与排除标准的儿童PFCD患者的临床资料,评估肛瘘愈合率和临床缓解率。采用二元Logistic回归分析识别影响肛瘘愈合的因素,并绘制预测指标的受试者工作特征曲线(ROC)评估指标的预测效能。

结果

纳入71例PFCD患者,中位随访时间为115(100,127)周。随访终点结果显示肛瘘愈合率为45.1%(32/71),影像学瘘管愈合率为39.4%(28/71),克罗恩病临床缓解率为54.9%(39/71)。单因素逻辑回归结果显示,身体质量指数(BMI)(OR:0.851,95%CI:0.725~0.999,P=0.049)是瘘管愈合的保护因素,儿童克罗恩病活动指数(PCDAI)(OR:1.347,95%CI:1.168~1.554,P<0.001)、克罗恩病简化内镜评分(SES-CD)(OR:3.460,95%CI:1.839~6.509,P<0.001)和瘘管复杂程度(OR:21.562,95%CI:4.499~103.346,P<0.001)是瘘管愈合的危险因素。多因素逻辑回归结果显示,PCDAI是影响肛瘘愈合的独立危险因素(OR:1.309,95%CI:1.087~1.576,P=0.005)。基于PCDAI构建的ROC曲线具有良好的预测效能(AUC=0.907,95%CI:0.832~0.981,敏感度0.769,特异度0.969,阳性预测值0.968,阴性预测值0.775,约登指数0.738)。

结论

保留括约肌挂线术联合ADA可显著改善儿童PFCD患者的临床症状。基线PCDAI预测儿童PFCD的肛瘘愈合结局准确性较高,可辅助临床决策。

Objective

To evaluate the long-term effectiveness of sphincter-preserving seton surgery combined with Adalimumab (ADA) in pediatric patients with perianal fistulizing Crohn’s disease (PFCD), and to explore predictive factors affecting efficacy.

Methods

A retrospective analysis was conducted on the clinical data of pediatric patients who met the inclusion and exclusion criteria between January 1, 2021 and December 31, 2024, to healing rate of anal fistula and the clinical remission rate. Binary logistic regression analysis was used to identify factors affecting fistula healing, and a receiver operating characteristic (ROC) curve was plotted for predictive indicators.

Results

Seventy-one patients were included. The median follow-up time was 115 (100, 127) weeks. At the follow-up endpoint, 32/71 (45.1%) patients achieved healing of anal fistulas, and 39.4% (28/71) achieved fistula healing under MRI, and 39/71 (54.9%) patients achieved clinical remission. Univariate logistic regression results indicated that Body Mass Index (BMI) (OR: 0.851, 95%CI: 0.725~0.999, P=0.049) was a protective factor associated with fistula healing, while PCDAI (OR: 1.347, 95%CI: 1.168~1.554, P<0.001), SES-CD (OR: 3.460, 95%CI: 1.839~6.509, P<0.001) and fistula complexity (OR: 21.562, 95%CI: 4.499~103.346, P<0.001) were risk factors for poor fistula healing. Multivariate logistic regression showed that PCDAI was an independent risk factor affecting fistula healing in pediatric patients with PFCD (OR: 1.309, 95%CI: 1.087~1.576, P=0.005). The ROC curve constructed based on PCDAI demonstrated good predictive performance (AUC=0.907, 95%CI: 0.832~0.981, sensitivity 0.769, specificity 0.969, positive predictive value 0.968, negative predictive value 0.775, Youden index 0.738).

Conclusion

Sphincter-preserving seton surgery combined with Adalimumab is effective for treating PFCD. Baseline PCDAI has high accuracy in predicting perianal fistula healing outcomes in pediatric PFCD, which can assist clinical decision-making.
