Chronic constipation is a frequent finding in children. In this age range, the concomitant occurrence of megarectum is not uncommon. However, the definition of megarectum is variable, and a few data exist for Italy. We studied anorectal manometric variables and sensation in a group of constipated children with megarectum defined by radiologic criteria. Data from this group were compared with those obtained in a similar group of children with recurrent abdominal pain.
Anorectal testing was carried out in both groups by standard manometric technique and rectal balloon expulsion test.
Megarectum patients displayed discrete abnormalities of anorectal variables and sensation with respect to controls. In particular, the pelvic floor function appeared to be impaired in most patients.
Constipated children with megarectum have abnormal anorectal function and sensation. These findings may be helpful for a better understanding of the pathophysiological basis of this condition.
慢性便秘在儿童中很常见。在这个年龄段，巨直肠并发并不罕见。然而，巨直肠的定义并不统一，意大利的相关数据较少。我们研究了一组经放射学标准定义为巨直肠的便秘儿童的肛门直肠测压变量和感觉。将该组数据与另一组患有复发性腹痛的类似儿童的数据进行比较。
两组均采用标准测压技术和直肠气囊排出试验进行肛门直肠检测。
与对照组相比，巨直肠患者的肛门直肠变量和感觉存在明显异常。特别是，大多数患者的盆底功能似乎受损。
患有巨直肠的便秘儿童存在肛门直肠功能和感觉异常。这些发现可能有助于更好地理解这种疾病的病理生理基础。
