Retentive (impacted) and nonretentive encopresis should be separated because the treatment for each type is radically different. The rectal examination is the definitive test. Children with retentive encopresis need enemas, stool softeners, and mandatory sitting on the toilet; children with nonretentive soiling usually respond to behavioral management.
潴留型（便秘型）和非潴留型大便失禁应区分开来，因为针对每种类型的治疗方法截然不同。直肠检查是决定性的检测手段。潴留型大便失禁的儿童需要灌肠、使用大便软化剂，并强制坐在马桶上；非潴留型大便失禁的儿童通常对行为管理有反应。
