Irritable Bowel Anismus

Wael Solh and Eric G.Weiss

The causes of constipation and altered defecation are mul-tifactorial, and the manifestations are varied. Etiologies of constipation or altered defecation can be divided into two categories - slow transit constipation, and pelvic outlet obstruction. Pelvic outlet obstruction includes etiologies such as paradoxical or nonrelaxation of the puborectalis muscle or anismus (nonrelaxation of the "anal canal"), rectal prolapse or intussusception, and nonemptying rec-toceles. Associated findings may include perineal descent and solitary rectal ulcer syndrome.

In normal defecation, the pelvic floor muscles and external anal sphincter are voluntarily inhibited resulting in an increase in the anorectal angle with increasing intraabdominal pressure. Patients with nonrelaxing puborectalis syndrome (NRPS) or anismus are unable to voluntarily inhibit contraction of the pelvic floor. When inappropriate function of the puborectalis muscle (inappropriate contraction or failure to relax) results in the inability to evacuate the rectum, the condition is termed anismus. Unlike levator syndrome, anismus is painless.
