在这项研究中，56% 患有慢性便秘和大便失禁的儿童无法通过直肠气球排便。他们中的大多数人在排便试验期间肛门外括约肌异常收缩。在遵循传统治疗方案一年后，86% 的人仍然无法通过气球排便。只有 14% 无法通过球囊排便的患者在 1 年内康复，而能够排便的患者则有 64% 康复 (p‐0.02)。无法放松外括约肌的患者只有 13% 在 1 年后康复，而能够放松外括约肌的患者则有 70% 康复了 (p‐0.01)。此外，在初次检查期间出现腹部粪便肿块的患者中，无论是否能够排便球囊，均未康复（p‐0.001）。这项研究表明，异常的排便动力学和便秘的严重程度是慢性便秘和大便失禁持续存在的预测因素。
In this study 56% of children with chronic constipation and encopresis were unable to defecate rectal balloons. Most of them had an abnormal contraction of the external anal sphincter during defecation trials. Eighty‐six percent were still unable to defecate balloons 1 year later after having complied with a conventional treatment program. Only 14% of patients unable to defecate balloons had recovered by 1 year, whereas 64% of patients able to had recovered (p ‐ 0.02). Only 13% of patients unable to relax the external sphincter had recovered by 1 year, whereas 70% of those able to do so had recovered (p ‐ 0.01). In addition, none of the patients with an abdominal fecal mass present during the initial examination independent of ability or inability to defecate balloons had recovered (p ‐ 0.001). This study shows that abnormal defecation dynamics and the severity of constipation are predictors for persistence of chronic constipation and encopresis.
