笔者采用表面电极对216名正常儿童作了肛门外括约肌肌电图，连续观察了（肛门外括约肌在静止、刺激和自主收缩状态的）肌电活动。

Electromyogram of external anal sphincter was recorded by surface electrode in 216 healthy children .

根据瘘管与肛门外括约肌深部的位置关系，分为低位肛瘘和高位肛瘘。

Therapeutic of tunnel fistulectomy and primary suture in the treatment of high anal fistula ;

目的：为带蒂大收肌移植修复肛门外括约肌提供解剖学资料。

Objective : To provide anatomical data for transplanting adductor magnus flap and repairing sphincter ani external .

结论神经压榨股薄肌转移代肛门外括约肌重建术治疗大便失禁是一种较为有效的方法。

Conclusion The rebuilding operation of external anal sphincter with gracilis graft is an effective method to treat fecal incontinence .

32例保留肛门外括约肌低位直肠癌保肛术的临床分析

Clinical Analysis of Preserving External Sphincter of Anus for 32 Cases of Anus Preservation Operation on Low Position Rectal Cancer

高位肛瘘是肛肠科疑难病之一，其管道穿越肛门外括约肌深部以上，给治疗带来很大困难。

The canal of high anal fistula lies through or above the deep headquarter of external sphincter , which brings much difficulties for the therapy .

目的对肛门外括约肌肌力进行量化分级，并探讨其在脊髓神经不完全损伤恢复期的意义。

Objective To study the quantitative grade of sphincter ani externus myodynamia and to discuss the significance of using in convalescent of incomplete spinal cord injuries .

结论：肛门外括约肌存在压力偏位现象，这种偏位的形成有助于肛门节制。

CONCLUSION : The phenomena of pressure asymmetry existed in external sphincter muscle of anus , and this kind of asymmetry formation is helpful to anus continence .

并对患者术后的肛门外括约肌肌电图、肛管直肠内压、直肠感觉功能、肛门液体节制功能进行了检测。

After the operation , the patient 's EMG of the external sphincter , anorectal internal pressure , rectal sensory function and controlling function of anal fluid were determined .

结论大多数脊柱裂患者不能自主收缩肛门外括约肌，排便时表现为盆底功能紊乱型直肠肛管压力曲线，同时直肠感觉功能也受到严重损害。

Conclusions Most spina bifida patients lose the ability to voluntarily contract their external anal sphincter , presenting with pelvic floor dysfunction during straining maneuver and severe rectal sensation function damage .

结果电刺激大鼠前列腺后，在同侧生殖股神经、髂腹股沟神经、髂腹下神经和股外侧皮神经记录到动作电位，肛门外括约肌记录到较为的恒定的复合肌肉动作电位。

Results Action potentials from the iliohypogastric , genitofemoral , lateral femoral cutaneous , femoral , sciatic nerves compound muscle action potentials ( CMAP ) from the anal external sphincter were recorded .

目的总结神经压榨股薄肌转移代肛门外括约肌重建术治疗小儿大便失禁的指导原理、手术方法、操作经验、疗效以及并发症。

Objective To summarize theory , method , experience , curative effect of operation and complications of the rebuilding operation of external anal sphincter with gracilis graft in the treatment for fecal incontinence .

另外，现代研究证明，肛门外括约肌的完整性、内括约肌反射的完整性、肛门局部上皮电生理感觉以及瘢痕组织引起的肛管缺损是影响肛门节制功能的主要因素。

In addition , studies have shown that the integrity of the integrity of the external anal sphincter , internal sphincter reflex , anal local epithelial electrophysiological feel the scar tissue caused by the anal canal defect is a major factor affecting the anus restraint function .

资料提炼：共收集到关于括约肌压力偏位的文献20篇，有关括约肌解剖构筑的文献200篇，有关肛门外括约肌生物反馈训练的文献39篇，与本文密切相关的文献19篇，排除240篇。
