先天性巨结肠及同源病患儿术后直肠肛管测压与分析

目的分析先天性巨结肠(HD)及同源病(HAD)术后患儿直肠肛管测压参数及其临床意义。方法对56例巨结肠术后患儿,包括32例HD和24例HAD,进行随访,并根据排便功能分为正常组、污粪组及便秘组。同时进行直肠肛管测压检查。根据不同病理分型,临床症状及随访时间比较分析测压结果。结果直肠肛管抑制反射(RAIR)重现率为55%,术后1a内RAIR重现率明显低于1a以上患儿(P<0.05)。HD术后患儿肛管直肠蠕动频率明显大于HAD(P<0.05)。按主观症状将患儿分为正常、污粪和便秘组,便秘组肛管/直肠静息压之比及高压带长度与前二组比较有显著差异(Pa<0.01)。结论部分患儿术后RAIR可恢复,并与术后时间有关,HD术后肛门功能改善优于HAD。影响术后测压结果的因素是多方面的。

Quantitative evaluation of the anal sphincter by the tendency presented in the manometric asymmetry variations

OBJECTIVES: To assess the tendency of manometric asymmetry, and to quantitatively evaluate the function of the anal sphincter. METHODS: Using the PC polygram HR at the states of relax and squeeze, we compared the values of pressure asymmetry in the anorectum of 27 normal children with that of 12 children with fecal incontinence. RESULTS: In the two states, the anal sphincter in normal children showed not only the gradient of pressure, but also a gradient of pressure asymmetry. Children with fecal incontinence did not show any gradients. CONCLUSION: Gradients of pressure and pressure asymmetry can quantitatively evaluate the function of the anal sphincter.
