A computerized vector manometry and MRI study in children following posterior sagittal anorectoplasty.

摘要: The study was designed to evaluate computerized eight-channel vector manometry (8CVM) and pelvic floor magnetic resonance imaging (MRI) as methods assess the anal sphincter following posterior sagittal anorectoplasty (PSARP) for anorectal malformations, in particular functional capacity of structures correlation with postoperative MRI findings. Seventeen children had been operated upon a rectovesical, -urethral, or -vaginal fistula including one female cloacal malformation; 4 secondary PSARP. Mean follow-up 5.57 years. Continence evaluated modified Kelly score. A CVM technique an perfusion catheter used. In addition software-supported data, manometric parameters included score-system assessing three different pressure zones canal qualitatively on three-dimensional image profile. same procedure performed sagittal, oblique axial, coronal MRI. Furthermore, thickness muscle assessed at level maximal mean segmental pressure. All decreased absolute vector-volumetry values rest squeezing. Correlation clinical score poor. course similar (R = 0.425; P 0.1). Thirteen demonstrated normal increased length; 5 these high-pressure zone (HPZ). position anorectum muscles could be by anatomic 11 cases, nearly correctly positioned 4, ectopic 1 child. detected 2 cases malposition, 10 anatomic, nearly-anatomic HPZ significantly high 0.801; < 0.0001). 8CVM is thus highly sufficient illustrating function musculature seen Both only moderately reflect follow-up, since continence depends more than ability.
