两种术式治疗后半蹄铁型肛瘘的疗效对比分析

Comparison on the Therapeutic Efficacy of Two Procedure in the Treatment of Posterior Semi-horseshoe Anal Fistula

为探讨治疗后半蹄铁型肛瘘的手术方式及疗效，我们采用隧道式瘘管剔除对口引流术治疗后半蹄铁型肛瘘38例（A组），隧道式拖线术治疗34例（B组），并对两组疗效进行对比分析。结果显示，两组治愈率均为100％，其中B组4例经二次扩创后治愈，随访3年无复发。两组均无肛门畸形、肛门失禁等并发症。A组平均疗程为（26．2±3．4）d，B组平均疗程为（28．3±3．1）d。术后2级以上疼痛A组为89．5％（34／38），平均持续时间（7．3±3．2）d；B组为94．1％（32／34），平均持续时间（12．8±3．8）d。结果表明，隧道式瘘管剔除对口引流术治疗后半蹄铁型肛瘘疗效显著。

For exploring procedure and its curative effect in treating posterior semi-horseshoe anal fistula, the 38 patients underwent the procedure of tunnel fistula resection and orifice-orifice drainage（the group A） ,while 34 cases underwent the procedure of tunnel thread drawing（the group B）. As results, 100% of cure rate was achieved in both groups,secondary debridement was applied in 4 eases in group 13,no recurrence was found during 3-year follow up;there ws no such complications as anal malformation and anal incontinence;the average treatment course was （26.2±3.4） days in group A and （28.3±3.1） days in group B;postoperative pain（2 degree and above） in group A was 89.5 % （34/38）, lasting for （7.3± 3.2） days; while that in group B was 94.1% （32/34） ,lasting for （12.8±3.8） days. It is concluded that the procedure of tunnel fistula resection and orifice-orifice drainage can ensure better therapeutic results in the treatment of posterior semi-horseshoe anal fistula.
