Preoperative electromyographic examination is very useful in locating the external sphincter muscles and determining their degree of development. Electromyographic examinations showed the relatively abundant distribution of the external sphincter muscles in the perineum even in high-type anomalies. The results obtained by these examinations lead to the conclusion that preserving both the puborectal and external sphincter muscles should be the main consideration in surgery for anorectal malformations.
术前肌电图检查对于定位外括约肌并确定其发育程度非常有用。肌电图检查显示，即使在高位畸形中，外括约肌在会阴的分布也相对丰富。这些检查结果得出的结论是，在肛门直肠畸形手术中，保留耻骨直肠肌和外括约肌均应作为主要考虑因素。
