PH-metrie et reflux gastro-oesophagien

The PH-metry is a direct technique of quantitative exploration of gastro-esophagian reflux largely developed during this last decade. our aim is to describe three principal techniques of registration [short or provoked, average or post prandial, long and nyctohemeral], their way of realigation, their respective advantages and disadvantages, and to emphasize the principal indications. Insisting upon the interest of such an exploration, we recommend the use of the post prandial or nyctohemeral PH-metry

Physiologie du bas oesophage: macanisme de la continence et causes du RGO

The physiology of low esophagus has largely benefited from the development of functional exploration techniques. Esophagian continence causes the intervention of anatomic factors. The lower sphincter of the esophagus [LS.e] is the most important physiological element. Its regulation is complicated, multifactorial [nervous, hormonal, pharmacologic, alimentary]. The motoricity of low esophagus is studied in rest, then during the deglutition. The LSO incurs the action of different forces which exercise themselves on the low esophagus and the diaphragm. The integration of these forces realizes a balance, ranked to an equation of the continence. Other factors intervene in the gastroesophagian reflux, these are: the gastric drain and secretion and above all the clearance of esophagus whose good functioning is the security of the integrity of the esophagian mucosa

Interet de la manometrie anorectale dans les colopathies fonctionnelles

Since the advent of anorectal manometry in the digestive pathology, numerous anomalies of rectoanal powering have been reported. This exploration has known no couterindication and guides the therapeutic choice [biofeed back, surgery.] After studying normal results and manometric anomailies found in the literature concerning constipation and anal incontinence, we have found it useful to report our own experiment about 18 patients presenting a functional colopathy. This 14 of these colopathies[11%] are anorectal dyschezias. in all cases and according to the data of the literature, the PRAI is always there. in 3 cases, the abtaining threshold of PRAI is high. Also in 3 cases, there exists a hypertonia of internal sphincter. one case of anism is shown up. AbdominoPelvian asynchronismis found in 11 sick people and an increasing rectal compliancy in 11 patients as well. No case of sphincteric incontinence is found again
