sliding hernia
Last reviewed 01/2018
If an extraperitoneal viscus forms one side of a hernial sac, it is thought to have slid down the canal pulling peritoneum with it, hence the name hernia en glissade. Thus, on the right the caecum forms the posterior wall and on the left, the sigmoid colon. The bladder may also be involved.
The sac can contain other loops of bowel, and the gut forming the wall of the sac can be strangled by the external ring.
