Disorders of function include defecation disorders, fecal incontinence, and proctalgia syndromes, whereas disorders of structure include anal fissure and hemorrhoids. Each section reviews the definitions, epidemiology and/or pathophysiology, diagnostic assessment, and treatment recommendations of each entity. These recommendations reflect a comprehensive search of all relevant topics of pertinent English language articles in PubMed, Ovid Medline, and the National Library of Medicine from 1966 to 2013 using appropriate terms for each subject. Recommendations for anal fissure and hemorrhoids lean heavily on adaptation from the American Society of Colon and Rectal Surgeons Practice Parameters from the most recent published guidelines in 2010 and 2011 and supplemented with subsequent publications through 2013.

The yearly number of examinations was associated with years of experience and specialty type. Patient refusal rates were lowest among gastroenterology (GI) faculty and highest among primary-care doctors. Refusal rates were negatively correlated with comfort level of the physician in performing a DRE. More gastroenterologists used sophisticated methods to detect anorectal conditions, and gastroenterologists were more confident in diagnosing them. Confidence in making a diagnosis with a DRE was strongly associated with the number of DREs performed annually. The higher frequencies of performing a DRE, lower refusal rate, degre...
