目的评价经括约肌间瘘管结扎术(ligation of the intersphincteric fistula tract,LIFT)联合直肠推移瓣术(endorectal advancement flap,ERAF)治疗高位复杂性肛瘘的临床疗效。方法2016年8月~2021年12月我院收治的高位复杂性肛瘘病人40例...目的评价经括约肌间瘘管结扎术(ligation of the intersphincteric fistula tract,LIFT)联合直肠推移瓣术(endorectal advancement flap,ERAF)治疗高位复杂性肛瘘的临床疗效。方法2016年8月~2021年12月我院收治的高位复杂性肛瘘病人40例,根据抽签法随机分成试验组和对照组,每组各20例。试验组采用LITF+ERAF,对照组采用LIFT,随访6~12个月,比较其临床疗效,比较创面愈合时间、治愈率、术后第1天疼痛程度、肛门功能和复发率。结果两组术后第1天疼痛程度、创面愈合时间、治愈率比较差异无统计学意义(P>0.05)。两组术前、创面愈合后、术后6个月的Wexner肛门失禁评分、肛管静息压和肛管最大收缩压比较差异无统计学意义(P>0.05);两组创面愈合后、术后6个月的肛管静息压和肛管最大收缩压分别与其自身术前比较,差异有统计学意义(P<0.05)。随访6~12个月,试验组无复发,对照组复发3例,差异有统计学意义(P<0.05)。结论LITF联合ERAF疗效好、痛苦小、病程短、术后复发率低、肛门功能影响小。展开更多
