由于评估肛门直肠功能的传统方法不一定能在接受肛门直肠畸形 (ARM) 手术的患者的研究结果和症状之间提供良好的相关性，因此我们最近引入了粪便流量计 (FFM) 来模拟自然肛门直肠排空。本研究的目的是体现重要参数来阐明 FFM 上肛门直肠活动的动态。将 FFM 参数与 24 名接受 ARM 手术的患者的测压参数和 Kelly 临床评分 (KCS) 进行比较。 fecoflow 模式共有三种，即块状（B）型、节段（S）型和扁平（F）型。 B 型或 S 型模式见于被分类为“临床良好”的患者。 fecoflow 模式与手术过程和 KCS 之间存在密切关系（分别为 P= 0.01 和 0.001）。最大粪流流速（Fmax）准确反映了结直肠内预期生理盐水溶液的耐受率（TR）、排便率（ER）和KCS。Fmax>45ml/s或TR>70%或ER>50%统计学上视为大便失禁的边界。因此，fecoflow 模式可能反映盆底肌肉的运动活动。 FFM 对接受 ARM 手术的患者的肛门直肠运动活动进行了定量和定性评估。
Because conventional methods of evaluating anorectal function do not necessarily provide good correlations between investigative results and symptoms in patients who have undergone surgery for an anorectal malformation (ARM), we recently introduced fecoflowmetry (FFM) to simulate natural anorectal evacuation. The purpose of this study was to embody significant parameters to elucidate the dynamics of anorectal activity on FFM. The parameters of FFM were compared with those of manometry and Kelly's clinical score (KCS) in 24 patients who underwent surgery for an ARM. There were three fecoflow patterns, namely, block (B) type, segmental (S) type, and flat (F) type. The B-type or S-type patterns were seen in patients classified as "clinically good." There were close relationships between the fecoflow pattern and both the operative procedure and the KCS (P= 0.01 and 0.001, respectively). Maximum fecal stream flow rate (Fmax) precisely reflected the tolerance rate of intended normal saline solution in the colorectum (TR), the evacuative rate (ER), and KCS.Fmax> 45 ml/s or TR > 70% or ER > 50% was statistically regarded as the borderline of fecal continence. Thus, the fecoflow pattern might reflect the motor activity of the pelvic floor muscle. FFM provided quantiative and qualitative evaluations concerning anorectal motor activity in patients who had undergone surgery for an ARM.
