122例正常儿作直肠肛管测压检查均有直肠肛管松弛反射,无假阴性.肛管高压区长度1.87～2.70cm,肛管静患压2.28～3.55kPa(17.14～26.64mmHg),2月～3岁组与～7岁组比较,此两项统计学上有显著性差异,说明正常儿肛管的解剖结构、生理机能逐渐完善.受试儿中53～66%,有直肠适应性反应,观察95例直肠顺应性,最大范围为17.3～56.3ml/kPa(2.3～7.5ml/mmHg).从乙状结肠至肛管,蠕动波波幅基本一致,但蠕动频率和测得蠕动的机率明显增加.

From 1986 to 1987,anorectal manometry was carried out in a total of 122 normal individuals including infants(group Ⅰ)and children(group Ⅱ).All of them gave rise an anorectal relaxing reflex,without pseudonegative results.The length of high pressure segment of anal cr.nal was 1.87-2.70cm,the anal static pressure was 17.14-26.24mmHg.There was an obvious statistical difference between the group Ⅰ and Ⅱ.It indicates that the anal anatomical structures and physiological functions in normal children are in developing state,53-66% of children received manometry evaluation had a rectal adaptive reaction which is increasing with the child's age.It suggest that there be a course of maturation of the rectal neural regulation mechanism in childhood.The rectal compliance(△v/△p)of 95 cases ranged 2.3-7.5ml/mmHg in maximum.The amplitude of peristalsis waves is generally equal in the distal part of colon,but from the sigmoid downward the frequency and checking rate of the peristalsis are increasing markedly at the level of anal canal.This mechanism may help produce a."potential difference of opposite direction" at the distal of alimentary tract to maintain a high pressure state in the anal canal.
