摘要:

目的 评估改良经肛括约肌间切开(TROPIS)术对高位肛瘘患者术后肛门功能的长期影响,并分析影响术后肛门功能的危险因素。方法 采用回顾性病例对照研究方法。纳入行手术治疗的高位肛瘘患者181例,根据手术方式不同分为试验组(采用改良TROPIS术治疗)84例与对照组(采用切开挂线术治疗)97例,随访12~36个月(中位时间21个月),比较2组一般情况、治愈率及肛门功能的差异。采用Logistic回归分析影响术后肛门功能的风险因素,受试者工作特征(ROC)曲线、曲线下面积(AUC)及Hosmer-Lemeshow检验评价预测效能。结果 试验组的复发率为8.33%,低于对照组的20.62%,术后肛门控气、生活方式改变评分及Wexner失禁总评分较术前增加(P<0.01),但各项评分试验组低于对照组(P<0.01)。全组79例患者术后肛门功能下降,Logistic回归分析结果显示,体质量指数增高(OR=4.579)、马蹄形肛瘘(OR=158.011)、瘘管数目较多(OR=8.789)、病变牵涉外括约肌(OR=6.883)及手术方式中切开挂线术治疗(OR=7.082)是影响高位肛瘘患者术后肛门功能下降的独立危险因素。联合各独立危险因素,总的预测概率AUC=0.903(95%CI:0.859~0.947,P<0.01),Hosmer-Lemeshow检验结果显示,χ2=5.603,P=0.587,各独立危险因素联合预测具有良好的区分度和校准度。结论 相比切开挂线术,改良TROPIS术治疗高位肛瘘更加安全有效;但该术式仍然会导致术后肛门长期功能降低,针对肥胖和瘘管走行复杂的患者,术中应尽可能保护肛门括约肌。

Abstract:

Objective To evaluate the long-term effect of modified TROPIS on postoperative anal function in patients with high anal fistula, and analyze the risk factors influencing postoperative anal function. Methods A retrospective case-control study was used in this study. A total of 181 patients with high anal fistula who underwent surgical treatment were included. Patients were divided into the experimental group (n = 84) and the control group (n = 97) according to the surgical method. The experimental group was treated with modified TROPIS, and the control group was treated with incision-thread-drawing procedure. Follow-up period was 12-36 months (median, 21 months). The general condition, cure rate and anal function were compared between the two groups. Logistic regression analysis was used to analyze risk factors influencing postoperative anal function, and the area under the ROC curve (AUC) and the Hosmer-Lemeshow test were used to evaluate the predictive efficacy. Results The relapse rate was 8.33% in the experimental group, which was significantly lower than 20.62% in the control group. The total score of postoperative anal gas control, lifestyle and Wexner incontinence were significantly higher after surgery compared with those before surgery (P<0.01), but each score was significantly lower than that in the control group (P<0.01). Postoperative anal function declined in 79 patients. Logistic regression analysis showed that body mass index (OR=4.579), horseshoe anal fistula (OR=158.011), number of fistulas (OR=8.789), lesion involving external sphincter (OR=6.883) and surgical method (OR=7.082) were independent risk factors for postoperative anal function decline in patients with high anal fistula. Combined with each independent risk factor, the AUC of overall predictive probability was 0.903 (95%CI: 0.859-0.947, P<0.01). Hosmer-Lemeshow test demonstrated that χ2 =5.603, P=0.587, indicating that the combined prediction of each independent risk factor had high discrimination and accuracy. Conclusion Compared with the incision-thread-drawing procedure, modified TROPIS procedure is safer and more effective in the treatment of high anal fistula. However, this surgery still leads to long-term postoperative anal function decline. For patients with obesity and complicated fistula, anal sphincter should be protected as much as possible during surgery.
