先天无肛肛门成形术后大便失禁的测压分析

目的 :通过肛门直肠测压法 ,对先天无肛肛门成形术后大便失禁患儿的肛门功能进行准确的客观评定。方法 :对25例先天无肛肛门成形术后大便失禁患儿进行临床评分及对肛门直肠测压 ,并与20例对照组进行比较。结果 :病例组最大自主收缩压、最大收缩时间、收缩向量容积、肛管静息压、肛管直肠压力差、高压带、舒张向量容积均低于对照组 (P<0.05) ,直肠感觉阈高于对照组 (P<0.05)。且畸形位置越高 ,评分越低 ,差异越显著。结论 :肛门直肠测压法有助于更好地了解排便功能障碍的发病原因 ,并为个体化的治疗奠定了基础。

Study on Anorectal Manometry in Postoperative Incontinence in Children with Imperforate Anus

To explore the mechanisms of postoperative incontinence in children with imperforate anus by manometry.Methods:Clinical score and manometry examinations were recorded in 25 patients with postoperative incontinence, and compared with that in 30 subjects of normal control.Results:The parameters which included maximum contraction amplitude and duration, squeezing vector volume, anal canal resting pressure, anorectal pressure difference,high pressure zone, and resting vector volume in postoperative incontinence group were lower than those in control group (P<0.05).Rectal sensation threshold in postoperative incontinence group was higher than those in control group (P<0.05).The higher the position of malformation was, the grade was lower. Conclusion:Manometry is helpful to realize the mechanism of incontinence.
