Incarcerated hernia or wound dehiscence are responsible for more than 10% of small bowel obstructions. The complication is easily recognized when hernia or wound dehiscence was previously diagnosed. Difficulties occur when mass is deeply located in a thick abdominal wall or inside the inguinal canal. Femoral hernias and direct inguinal hernias are those which strangulate the most. Strangulation in wound dehiscence is the most severe. Strangulated hernia should be routinely excluded in patient with intestinal obstruction, to avoid inappropriate surgical approach.
