Level 1	A significant reduction in incidence of incisional hernia in patients undergoing elective midline laparotomy was achieved with prophylactic mesh reinforcement in onlay position compared with sublay mesh reinforcement and primary suture only
Level 1	Prophylactic mesh application at the time of primary colostomy formation is a promising method for the prevention of parastomal herniation
Level 1	Prophylactic mesh placement reduces the rate of incisional hernia in risk groups with morbid obesity, aortic aneurysm, or colorectal surgery
Level 3	Prophylactic mesh in the closure of emergency midline laparotomies is feasible for the prevention of incisional hernia
Level 2	Extraperitoneal colostomy was observed to lead to a lower rate of parastomal hernia and stoma prolapse versus transperitoneal
Level 2	Use of a resorbable synthetic mesh during emergency ostomy formation showed no significant preventive effect on formation of parastomal hernia after 1 year
