Cases of retrograde infringement in a "sliding" hernia

The concept of retrograde infringement is understood as infringement of one or more loops of the intestines, in which an eating disorder involves not only the parts in the hernial sac into suffering, but also, and to a greater extent, especially the part located in the free abdominal cavity. This, rare, form of infringement by Bendel was given the name Hernie en W, since in typical cases there are two loops in the hernial sac outward from the restraining ring, and inwardly from it in the abdominal cavity one connecting with a more severe eating disorder, depending on its bending mesentery or twisting of the entire loop. It is extremely rare that the median loop is little changed in comparison with the two in the hernial sac (the case of Nevsky).
