The study aims to prove differences or equalities in outcome for patients operated with or without a peristomal mesh in the sublay position when establishing a permanent colostomy.

Patients are randomized to 2 groups equal in number: a group with mesh implantation and a control group without mesh implantation.

Primary endpoint is Parastomal hernia. Secondary endpoints are operating time, infection, obstruction, stenosis, retraction, fistulae, skin related problems and reoperations. Endpoints are correlated to body mass index, previous hernia, age, concurrent illness and cause for colostomy. Patients are followed 4 years after operation with clinical examination

Inclusion Criteria:

• Condition with indication for establishing a permanent end-colostomy.

Exclusion Criteria:

• Age under 18
