Parastomal hernia is 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 2,3. 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.
