Is the Evaluation of Anal Distensibility by Endoflip® Technique Useful for the Diagnosis of Anismus?

2019-11-12 18:25:32 | BioPortfolio


Terminal constipation affects 13 to 20% of the french population. Anismus is defined by an absence of relaxation or a paradoxical contraction of the striated anal sphincter muscle during defecation.

Anismus is one of the main causes of terminal constipation. Anismus diagnosis is retained if 2 out of 3 examinations (manometry, electromyogram, defecography) are positive.

EndoFLIP® is a new medical device developed to measure distensibility of a hollow organ. Anal EndoFLIP® l could be a more sensitive and specific tool for detecting anismus in patients with distal constipation.

60 patients suffering from distal constipation will be included in order to perform, in addition to the usual examinations, an anal EndoFlip in order to test the sensitivity and specificity of this method for the diagnosis of anismus.

Medical and Biotech [MESH] Definitions

Tumors or cancer of the anal gland.

Protrusion of the rectal mucous membrane through the anus. There are various degrees: incomplete with no displacement of the anal sphincter muscle; complete with displacement of the anal sphincter muscle; complete with no displacement of the anal sphincter muscle but with herniation of the bowel; and internal complete with rectosigmoid or upper rectum intussusception into the lower rectum.

Surgical incision of the INTERNAL ANAL SPHINCTER typically in the treatment of FISSURE IN ANO; chronic ANAL FISSURE and FECAL INCONTINENCE.

A congenital abnormality characterized by the persistence of the anal membrane, resulting in a thin membrane covering the normal ANAL CANAL. Imperforation is not always complete and is treated by surgery in infancy. This defect is often associated with NEURAL TUBE DEFECTS; MENTAL RETARDATION; and DOWN SYNDROME.

A pair of anal glands or sacs, located on either side of the ANUS, that produce and store a dark, foul-smelling fluid in carnivorous animals such as MEPHITIDAE and DOGS. The expelled fluid is used as a defensive repellent (in skunks) or a material to mark territory (in dogs).
