parastomal hernia

Parastomal hernias (alternative plural: herniae) are defined as the protrusion of abdominal contents through an abdominal wall defect in the vicinity of the stoma.


The hernia may contain a loop of bowel forming the stoma itself, omentum, and/or intestinal loops other than that forming the stoma. Based on the contents of the sac, various classification schemes have been developed . However, clinically significant (and reportable) findings include presence or absence of hernia, bowel obstruction due to hernia and growth of sac since the last examination.
