Eight-four children, all of whom had imperforate anus, were evaluated by measuring the anal sphincter force (ASF). Sixty-three were boys, 46 of whom had a high imperforate anus and 17 of whom had the low anomaly. There were 7 girls with cloacal malformations, 7 girls with high type and 7 with low type of malformation. In all the boys with a high imperforate anus the ASF ranged from 50 to 300 g. Those boys with a low type had an average ASF of 513 g. Normal values vary from 480 to 600 g. Twenty-five of the boys with a high imperforate anus had undergone posterior sagittal anorectoplasty and none were clinically continent. Their ASF measurements were lower than in patients with spina bifida. Patients with a low anomaly, both boys and girls, were continent and had high ASF readings. The ASF is a simple, inexpensive, and objective measurement of fecal incontinence when this is the consequence of muscular inadequacy. A reproducible quantification is now available to compare results of different operations and different centres.
84名患有肛门闭锁的儿童接受了肛门括约肌力量（ASF）测量评估。其中63名是男孩，46名患有高位肛门闭锁，17名患有低位畸形。有7名患有泄殖腔畸形的女孩，7名高位畸形女孩和7名低位畸形女孩。所有高位肛门闭锁男孩的ASF范围为50至300克。那些低位类型的男孩平均ASF为513克。正常数值在480至600克之间。25名高位肛门闭锁男孩接受了后矢状位肛门直肠成形术，且无一例在临床上能控制排便。他们的ASF测量值低于脊柱裂患者。低位畸形的患者，无论男孩还是女孩，都能控制排便且ASF读数较高。当大便失禁是肌肉功能不足的结果时，ASF是一种简单、廉价且客观的测量方法。现在有一种可重复的量化方法可用于比较不同手术和不同中心的结果。
