皮瓣内移封闭内口术治疗高位肛瘘的临床研究

目的：探讨治疗高位肛痿的有效疗法。方法：治疗组15例，采用彻底切除内口感染灶，游离内口远端皮瓣向上牵拉覆盖于已切除内口上方。完整保留肛门直肠环；对照组15例，采用传统低位切开高位挂线治疗。结果：两组治愈率比较差异无统计学意义（P〉0．05），但在术后主要并发症的发生率以及肛管压力的影响上，差异有统计学意义（P〈0．05）。结论：内口封闭，可缩短疗程，减轻痛苦，避免并发症。

Clinical Research on the Treatment of High anal fistula by The Closing of Internal-opening Rectumpetal

Objective:To explore the effective method in the treatment of high anal fistula.Methods: The experiment group of 15 cases were treated with the division of low fistula,closing the internal opening and remnant antrum of the tunnel dissociated internal-opening rectum and pull it downwards to make it cover the low tissue of which the internal opening was closed,preserving the muscle ring which controls defecation.The control group of 15 cases were treated with traditional low incision and high thread-drawing.Results:There was no remarkable difference between two groups in curerate(P>0.05),but there was significant difference in the occurrence rate of the main complications after the operation and affection of sphincter pressure.Conclusion:Closing of internal opening,tunnel-style division of pipe wall in the muscle ring which controls defecation could shorten treatment course,reduce suffering and prevent complications.
