The purpose of this study is to determine if a mesh is effective in the prevention of a parastomal hernia when a permanent ostomy is performed through a laparoscopic approach.

Parastomal hernia (PH) is a very common complication after abdominal surgery that requires a permanent ostomy. This type of surgery is usually associated with processes that fall within the scope of Coloproctology.PH is difficult to deal with high rates of recurrence after surgical repair.This type of hernia remains a problem of first order, generating a significant consumption of health and economic resources and determining an impaired quality of life of these patients.Laparoscopic surgery is increasingly used in colorectal surgery.

Also with this type of approach is present the problem of prevention of PH. The use of a mesh in the repair of hernias is not discussed since the placement of a prosthesis significantly reduces the recurrence rate. There are now many types of prosthetic meshes available. A low weight mesh composed of large pores (about 5mm) with a high proportion of absorbable material and a layer of oxidized regenerated cellulose which is placed in the vicinity of the bowel is available on the market (PROCEED ®, Ethicon). The introduction of this low-weight mesh provides a good opportunity to prevent the development of an PH when we use a laparoscopic approach.
