目的 观察肛瘘手术后3个月后肛管手术区域超声图像变化,对肛瘘术后愈合情况进行评估.方法 对2015年1月~12月期间,在我院手术治疗的141例肛瘘患者术后3个月时肛管手术区域的直肠腔内超声检查图像进行超声评分,包括手术区域回声改变、边界清晰程度、形态转变和厚度的变化,超声评分为0~2分的为有瘢痕化趋势,超声评分3~4分的为有复发趋势.评价结果 与术后6个月时患者复诊的愈合情况进行对照分析.结果超声评价为瘢痕化趋势的0~2分组与评价为复发趋势的3~4分组,两组患者超声判断预后的准确性差异显著,x2=55.726,P=0.001,差异具有统计学意义,提示超声对0~2分组的术后3个月愈后评估准确度高,准确率100%,而对3~4分组的术后3个月愈后评估准确度相对低,准确率为58.3%.结论 直肠腔内超声操作简单,价格低,无创,患者易耐受,对肛瘘术后愈合良好的情况可以作出准确的分析评价,可以作为肛瘘术后评价的影像学方法.%Objective This paper aimed to observe anal fistula ultrasound image in the postoperative 3 months to evaluate healing of anal fistula. Methods From January 2015 to December 2015, the postoperative after 3 months echo anal ultrasound images of 141 patients with anal fistula were analyzed and scored, including changes of echo, boundary, shape and thickness. The score of ultrasound was 0~2 points, had a trend of scar, grade 3~4 points had a relapse tendency. The evaluation results were subsequently compared with follow-up visits after postoperative 6 months. Results The ultrasonic evaluation for scarring trend of 0~2 group and evaluation for relapse tendency of 3~4 group, the two groups of ultrasonic prognosis had significant difference, x2=55.726, P=0.001, 0~2 group had high accuracy, and for 3~4 group accuracy was relatively low. Conclusion Echo anal ultrasound can provide accurate analysis and evaluation on postoperative good health for anal fistula.
