Fecal incontinence is not a rare clinical pathology in general population. Although it is more common in geriatric population, fecal incontinence should not be underestimated in younger genders. Obstructive defecation syndrome (ODS) has become a well-known syndrome with different clinical etiology and symptoms. The main symptom is inability of proper rectal emptying, but it can also overlap with symptoms of incontinence. In this chapter, we emphasize on the assessment of ODS, focusing on the coexistence and clinical relation to fecal incontinence. Anorectal studies are of great importance for the evaluation of the symptoms. Biofeedback is the key to the proper management of patients with ODS, showing significant improvement in incontinence as well. Surgical treatment of anatomic deformities that cause ODS is also important.
