Ileus and intestinal obstruction are common diseases for the elderly. Ileus is caused as the results of severe pain, infections and medications. Intestinal obstruction is one of the first etiologies of surgical emergency procedures. Intestinal obstruction is mainly due to the abdominal wall hernias and oncologic problems in the elderly.
