INTERSTITIAL hernia is one of the three types of interparietal hernias, the others being the "superficial" and the "properitoneal." Barling1 defined interparietal hernia as a hernial sac, usually in the inguinal region, which passes between the layers of anterior abdominal wall. The sac may or may not be associated with, or communicate with, a sac in the common situation in the inguinal canal, passing down into the scrotum.
In the interstitial variety, the sac lies between the muscle layers of the abdominal wall.
These are rare types of hernias appearing rather sporadically in the literature and reported in detail by Lower and Hicken2 in 1931, and by Burton3 in 1953. Of major importance is the fact that when symptomatic, they go unrecognized preoperatively and are mostly diagnosed at the time of exploratory surgery. However, when they are asymptomatic, their association with other surgical conditions makes them still
