Highlights
Functional defecation disorder (FDD) is a common disorder underlying between 25 to 75% of cases of functional obstipation [1,2,3,4]
The defecometry test showed that the puborectal muscle and the external anal sphincter did not contribute to FDDs in all patients
With this study we demonstrate that the puborectal muscle and external anal sphincter do not act as a single functional unit in patients suffering from FDDs
Summary
Functional defecation disorder (FDD) is a common disorder underlying between 25 to 75% of cases of functional obstipation [1,2,3,4]. Based on the manometric abnormalities, the FDDs can be subdivided into one of several groups or types. Rao’s classification further subdivides these two groups into four types of FDDs (Types I-IV) [10,11]. Both classifications are based solely on abnormal pressure changes in the rectum and at the level of the external anal sphincter, thereby ignoring pressure changes at the level of the puborectal muscle. Classification currently used for functional defecation disorders (FDDs) assumes that the puborectal muscle and external anal sphincter act as a single functional unit. We hypothesize that the puborectal muscle and external anal sphincter do not act as a single functional unit
