Sténose du pyloreSSténose du pylorePyloric stenosisFrenchGastrointestinalNewborn (0-28 days);Baby (1-12 months)Stomach;Small IntestineStomach;Small intestineConditions and diseasesAdult (19+)NA2010-03-05T05:00:00ZMark Feldman, MD, FRCPC00398.000000000000Health (A-Z) - ConditionsHealth A-Z<h2>Qu’est-ce que la sténose du pylore?</h2><p>La sténose du pylore se produit lorsque l’ouverture entre l’estomac et l’intestin est bloquée. Cette ouverture est appelée le pylore . Il y a un muscle autour de cette ouverture. En temps normal, ce muscle permet, lorsqu’il se contracte, de garder la nourriture dans l’estomac et, lorsqu’il se détend, il laisse la nourriture passer de l’estomac à l’intestin. </p><p>Cette affection est plus courante chez les garçons que les filles.</p> <figure> <span class="asset-image-title">Sténose du pylore</span> <img src="https://assets.aboutkidshealth.ca/akhassets/Pyloric_stenosis_MED_ILL_FR.jpg" alt="" /> <figcaption class="asset-image-caption">Une sténose du pylore se produit lorsque le muscle situé en dessous de l'estomac est épais et serré. La nourriture ne peut passer aisément de l'estomac à l'intestin.</figcaption> </figure><h2>À retenir</h2> <ul> <li>On parle de sténose du pylore lorsque l’ouverture entre l’estomac et l’intestin devient très étroite.</li> <li>Les symptômes incluent le vomissement en jet persistant (pas seulement de recracher la nourriture) et la faim après le vomissement.</li> <li>Obtenez de l’aide médicale immédiatement si vous pensez que votre bébé est déshydraté ou qu’il est atteint de sténose du pylore.</li> <li>Votre bébé devra subir une opération chirurgicale simple. </li> </ul><h2>Signes et symptômes de la sténose du pylore</h2> <p>Les symptômes de la sténose du pylore apparaissent habituellement lorsque le bébé est âgé de 2 à 6 semaines. Cependant, ils peuvent se manifester plus tard. Ces symptômes peuvent comprendre:</p> <ul> <li><a href="https://akhpub.aboutkidshealth.ca/Article?contentid=746&language=french">vomissement</a> en jet persistant dans les 30 minutes après un boire</li> <li>faim constante (au début), particulièrement après le vomissement</li> <li>grande fatigue</li> <li>selles petites et moins fréquentes</li> <li>perte de poids</li> <li><a href="https://akhpub.aboutkidshealth.ca/Article?contentid=776&language=French">déshydratation</a> qui se manifeste par des pleurs sans larmes</li> </ul> <p>Ce trouble est rare chez les bébés de plus de trois mois. </p> <p>Si vous sentez que votre bébé est déshydraté ou si vous pensez qu’il souffre de la sténose du pylore, consultez un médecin immédiatement. En attendant de voir le médecin, offrez-lui souvent de petites quantités de nourriture.</p><h2>Les causes de la sténose du pylore</h2> <p>Lorsque le muscle autour du pylore est épais et tendu, il ne peut se détendre adéquatement et cela cause un blocage. Le pylore devient très étroit et le lait maternel ou la préparation pour nourrissons ne peut passer facilement de l’estomac à l’intestin. C’est ce qui fait vomir votre bébé. La chirurgie est alors nécessaire.</p> <h2>Ce que le médecin de votre enfant peut faire </h2> <p>Le médecin de votre bébé procédera à un examen physique et demandera un ultrason. Si votre bébé est atteint de sténose du pylore, il devra subir <a href="https://akhpub.aboutkidshealth.ca/Article?contentid=1017&language=English">une chirurgie</a>. Le chirurgien pratiquera une incision dans le muscle tendu entre l’estomac et l’intestin grêle, ce qui va permettre au muscle de se relâcher de façon à ce que l’estomac puisse se vider. La nourriture pourra alors passer facilement dans l’intestin grêle. </p> <p>Il s’agit d’une opération courante et simple qui n’aura pas d’incidence sur la croissance de votre bébé.</p><h2>À quel moment faut-il obtenir de l’aide médicale?</h2> <p>Consultez votre médecin immédiatement ou rendez-vous à la salle d’urgence la plus près si :</p> <ul> <li>votre bébé est déshydraté</li> <li>votre bébé vomit systématiquement en jet</li> <li>votre bébé perd du poids</li> <li>votre bébé n’urine pas autant que d’habitude</li> <li>votre bébé semble très fatigué ou somnolent</li> </ul>
