摘要: 目的 探讨改良经肛括约肌间切开术与肛门外括约肌裸化术治疗高位马蹄形肛瘘的疗效。方法 2021年2月~2024年3月收治的高位马蹄形肛瘘病人152例,按照手术方法分为观察组(82例)和对照组(70例),观察组实施改良经肛括约肌间切开术治疗,对照组实施肛门外括约肌裸化术治疗。比较两组病人的临床疗效、疼痛、肛门功能、肛管压力、术后并发症及复发率。结果观察组术中出血量低于对照组,差异有统计学意义(P<0.05)。术后7天、术后14天,两组疼痛程度评分逐渐降低,组间比较差异无统计学意义(P>0.05)。术后1个月、术后3个月,观察组病人的Wexner肛门失禁评分低于对照组,差异有统计学意义(P<0.05)。术后3个月,两组肛管静息压、肛管最大收缩压、肛管最大耐受量下降,观察组高于对照组,差异有统计学意义(P<0.05)。两组病人术后均未出现出血、感染等并发症。术后6个月,观察组复发率高于对照组,差异有统计学意义(P<0.05)。结论 改良经肛括约肌间切开术治疗高位马蹄形肛瘘能够降低病人术后肛门失禁的发生率,但相对于肛门外括约肌裸化术,术后复发率较高。

Abstract: Objective To explore the therapeutic efficacy of the modified separation of external anal sphincter and the external anal sphincter bareness in treating high-level horseshoe shaped anal fistula.Methods 152 patients with high-level horseshoe shaped anal fistula admitted to the hospital from February 2021 to March 2024 were selected and categorized into two groups based on the type of surgical method:an observation group with 82 cases and a control group consisting of 70 cases.The observation group received treatment the modified separation of external anal sphincter,while the control group received treatment the external anal sphincter bareness.Compare the clinical efficacy,pain,anal function,anal pressure,postoperative complications,and recurrence rate between the two groups.Results The intraoperative blood output of the observation group was lower than that of the control group (P<0.05).At 7 and 14 days after surgery,the pain level scores of the two groups gradually decreased,and there was no statistically significant difference between the groups (P>0.05).At 1 month and 3 months after surgery,the Wexner anal incontinence score of the observation group patients was lower than that of the control group (P<0.05).Three months after surgery,the resting pressure,maximum systolic pressure,and maximum tolerance of the anal canal decreased in both groups,with the observation group being higher than the control group (P<0.05).Both groups of patients did not experience postoperative complications such as bleeding or infection.Six months after surgery,the recurrence rate in the observation group was higher than that in the control group (P<0.05).Conclusion The modified separation of external anal sphincter treatment for high-level horseshoe shaped anal fistula can reduce the incidence of postoperative anal incontinence in patients,but the postoperative recurrence rate is higher compared to the external anal sphincter bareness.

Key words: the modified separation of external anal sphincter;the external anal sphincter bareness;high position horseshoe shaped anal fistula, anal incontinence, anal pressure
