Abstract

The primitive functional constipation is the main colorectoanal dysfunction and is clinically characterized by reduced weekly frequency of bowel movement, difficult evacuation, and increased stool consistency. The patient reports long straining, hard stools, sensation of incomplete evacuation, anorectal obstruction, and use of manual maneuvers (digital evacuation, lifting of the perineum). The diagnostic criteria of Rome III define this type of constipation (Table 1) (Bharucha and Pemberton 2013; Bharucha et al. 2006). Its mechanisms are slow intestinal transit and/or altered defecation. The imaging techniques dedicated to the study of evacuative alterations are barium proctography and magnetic resonance proctography; more recently, the perineal ultrasound of the posterior pelvic compartment was introduced. The study of the colonic transit time is executed when there is a suspicion of a functional constipation due to slow transit (Corazziari 2013).
