Thirty imperforate anus patients were investigated by anorectal manometry 5 to 10 years after a posterior sagittal anorectoplasty. Anal resting tone (ART) and anal squeezing pressure (ASP) were subnormal in most patients. Rectal volume (RV) and sensation to balloon distension were within the normal range. Rectoanal reflex inhibition was demonstrated in 9 of 30 patients. Soiling was more common in patients with a very low ART (less than 40 cm H2O) and a low ASP (less than 100 cm H2O). Constipation was more common in patients with a large RV (greater than 150 mL). Still, the correlation to clinical results was incomplete. As regards to the correlation to type of malformation the rectal atresia patients showed near normal results. The vestibular fistula patients were next in results showing rectoanal reflex inhibition in 5/6 patients. There was no difference in the results between bulbar and prostatic fistula patients.
对30例肛门闭锁患者在经后矢状位肛门直肠成形术后5至10年进行了肛门直肠测压检查。大多数患者的肛门静息压（ART）和肛门收缩压（ASP）低于正常水平。直肠容量（RV）和对球囊扩张的感觉在正常范围内。30例患者中有9例出现直肠肛门反射抑制。ART极低（低于40 cm H2O）和ASP低（低于100 cm H2O）的患者中，污粪更为常见。RV大（大于150 mL）的患者中便秘更为常见。然而，与临床结果的相关性并不完全。关于与畸形类型的相关性，直肠闭锁患者的结果接近正常。前庭瘘患者的结果次之，6例中有5例出现直肠肛门反射抑制。球部瘘和前列腺瘘患者的结果没有差异。
