Abstract

Un procédé permet de détecter la présence d'un néoplasie ou d'un cancer du colon ou du rectum. Il consiste à prélever un échantillon de glaire colorectale provenant du rectum du patient, à traiter l'échantillon avec un réactif de Schiff et à dépister une néoplasie ou un cancer du colon ou du rectum en fonction de la coloration produite par ce traitement dans l'échantillon. Ce procédé est rapide, simple, peu onéreux et constitue un examen de dépistage du cancer colorectal qui donne un faible pourcentage de résultats faussement positifs ou négatifs. On a prévu un matériel de dépistage.
