Answer

IRP refers to a full-thickness intussusception of the rectum during defecation. [42] Radiographically, different grades have been proposed, from low-grade (rectorectal intussusception) to high-grade (rectoanal intussusception) rectal prolapse. This kind of prolapse may lead to outlet obstruction and/or fecal incontinence. IRP plays an important role in the pathophysiology of obstructive defecation, which refers to the inability to empty the rectum satisfactorily during defecation.
