ABSTRACT
Objective To investigate the role of blood motilin and anorectal function in the pathogenesis of functional outlet obstructive constipation (OOC), and study if motilin and its receptor agonist are effective to treat OOC. [WTHZ]Methods Patients with OOC were selected according to colonic transit time and transit index. Twenty healthy subjects were also selected as control group. Anorectal manometry was performed, and blood motilin level was measured in patients with OOC and healthy subjects. Correlation between blood motilin level and anorectal function was analyzed. [WTHZ]Results Compared with healthy subjects, OOC patients had higher anal resting pressure, lower defecating pressure difference,larger minimum relaxation volume to elicit anorectal inhibitory reflex, and higher rectal sensation threshold. The plasma level of motilin was positively correlated with anal resting pressure, maximum squeeze pressure and anal defecating pressure, but was negatively correlated with defecating pressure difference between rectum and anal canal. Conclusion OOC patients had anal sphincter dysfunction in relaxtion, discoordination of annorectum during defecation, and Low sensitivity of rectum. OCC patients with the normal level of blood motilin may have more severe outlet obstructive tendency, and motilin and its receptor agonist are not suitable for treating OOC patients.
