Importance of Rectal Sensitivity Abnormalities in Functional Defecation Disorders / 胃肠病学

ABSTRACT

Many studies have shown that visceral sensitivity abnormalities are associated with the occurrence of intestinal dysfunction. Functional defecation disorders (FDD) is a type of constipation characterized by difficulty in stool passage, sensation of incomplete evacuation, or need for manual maneuvers to pass stool, which seriously affects patient's quality of life. It is reported that 64% of obstructive defecation patients having impaired rectal sensation, and the most common symptom of patients with rectal hyposensitivity (RH) is constipation. It can be hypothesized that rectal sensitivity abnormalities (especially RH) are closely related to FDD. This article reviewed the advances in study on the correlation between rectal sensitivity abnormalities and FDD, the etiological factor, examination and treatment of FDD.
