[Parastomal hernias].

The overall incidence of parastomal hernias is 35-50%. Different methods of hernia repairs (local fascial repair, stoma relocation and various types of mesh repairs) did not provide satisfactory results. Laparoscopic approach makes peristomal incision unnecessary and decreases the potential risk of mesh infection as well. In spite of all attempts the incidence of recurrent parastomal hernias is as high as 12-35%. These unsatisfactory results supported the idea of mesh implantation at the time of the initial stoma formation. In this study the authors inserted a self-designed two-layered special meshin 17 cases as a prevention and after 5 years follow-up period no parastomal hernias were recorded. The only complication noted was a minor stricture on the surface of the skin, that could have easily been corrected. Therefore, the authors support the idea of preventive mesh insertion at time of definitive stoma formation.
