Purpose of the guideline: Parastomal hernia is encountered frequently after permanent end colostomy. Previous systematic reviews suggest that the absolute risk of parastomal hernia is 30% by 12 months and 50% beyond 2 years. Using a prophylactic mesh, synthetic or absorbable, has been suggested to reduce the risk of parastomal hernia without increasing perioperative and longer-term stoma-related complications. Previous guidelines of the European Hernia Society provided a strong recommendation for the use of a prophylactic mesh when constructing an end colostomy. More recent data from randomized controlled trials (RCTs) provided conflicting evidence, giving rise to a debate over the optimum management of patients who are planned to have an end colostomy. In view of the new evidence and under consideration of the evolvement in the methodology of guideline development, the objective of this rapid guideline is to provide transparently developed, reliable, and evidence-informed update recommendation(s) on the use of prophylactic mesh for the prevention of parastomal hernia in patients who will have an end colostomy.
