Abstract
Objective: To assess the evacuation motility of functional outlet obstruction constipation (FOOC) to provide theoretical support for diagnosis and treatment of FOOC. Methods: Anorectal manomentry and anal electromyography (EMG) were carried out in 40 FOOC patients with normal colonic transit and 20 healthy controls. Anorectal motility parameters and motility index (MI) were calculated. Results: FOOC group had higher internal anal sphincter pressure than control group (P<0.05) at rest. Rectal sensation of FOOC group was lower than that of control group. Anal slow wave and irregular wave and MI increased, and spontaneous relax wave decreased in FOOC group compared with controls. There was no anal sphincter inhibitory reflex in 25% patients. In 52.5% patients, EMG appeared contradictory contractile activities. Conclusion: The results suggest that the patients with FOOC have dysfunction of the smooth muscle, striatal muscle and autonomic nerves.
