The Diagnostic Value of a Digital Rectal Examination Compared With High-Resolution Anorectal Manometry in Patients With Chronic Constipation and Fecal Incontinence

Abstract

DRE shows high sensitivity and positive predictive value in detecting dyssynergia compared with HRAM, and could therefore be used as a bedside screening test for the diagnosis of this disorder. Further studies are warranted to evaluate the correlation between DRE and HRAM in assessing anal sphincter pressure.

Efficacy and Predictors for Biofeedback Therapeutic Outcome in Patients with Dyssynergic Defecation

“…In our study population, type I dyssynergia was seen in 48.6%, type II dyssynergia in 28.4%, type III dyssynergia in 20.8%, and type IV dyssynergia in 2.1% of the patients. These rates are consistent with previous studies [6,41]. The pathogenic mechanisms are different for the different subtypes of DD, and the response to BFT may vary greatly between subtypes.…”

Utility of high-resolution anorectal manometry and wireless motility capsule in the evaluation of patients with Parkinson's disease and chronic constipation

“…Fourth, inherent limitations of the WMC in assessing CTT (ie, due to unidentifiable pH landmarks) or of the HRAM and BET in assessing dyssynergia (ie, due to non-physiological positioning, or abdominal muscle weakness) could have challenged their validity. Such scenarios were noted in our cohort but their impact is difficult to quantify 8 26. It has also been recently shown that although the various HRAM patterns are reproducible, they may be seen in healthy volunteers, questioning its overall utility in functional constipation 6.…”

Surgical decision-making in the management of children with intractable functional constipation: What are we doing and are we doing it right?

“…However, a digital rectal examination can provide valuable information on the presence of a rectal fecal mass (one of the six diagnostic Rome III criteria for FC) and be helpful in the assessment of anorectal sensation and sphincter tone [16][17][18]. Among the responders of this survey, the vast majority of physicians performed digital rectal examination routinely or occasionally.…”
