특집 : 변비의 병태생리와 진단

Constipation is a common symptom affecting approximately a quarter of population in Korea. To diagnose its etiology and to exclude the other organic or structural causes, many tests including digital rectal exam, laboratory tests, image studies, and physiologic studies are needed. Moreover, through these tests, the exact pathophysiology of constipation can be defined and used in the treatment of patients. Therefore, collaborative studies are necessary to determine the pathophysiology of this disorder.
