[Risk factors and prevent strategy of parastomal hernia].

Parastomal hernia is one of the common complications of stoma surgery with an incidence of more than 30%, which can be diagnosed by physical examination and abdominal CT. Risk factors of parastomal hernia might include stoma approaches including the selection of intestine, relationship between stoma and peritoneum, stoma location, aperture size, operation time and the patient's own conditions. It is essential to prevent parastomal hernia in order to improve patients' quality of life. Prophylactic mesh and perioperative care might prevent parastomal hernias. The mesh type might also influence the incidence of parastomal hernia. To reduce the incidence of recurrence of parastomal hernia, placement of mesh by the laparoscopic Sugarbaker technique was an effective surgical approach. How to prevent and repair parastomal hernia and cure parastomal hernia repair still needs further high-quality research to provide evidence.
