[Repair of parastomal hernia with marlex or prolene prosthesis in patients with Bricker-type urinary diversion]. / Correction de hernie parastomiale avec prothèse en Marlex ou Prolène chez des patients porteurs de dérivations urinaires type Bricker.

Creation of a cutaneous stoma can be associated with a number of complications, the most frequent being stenosis and parastomal hernia. A hernia can appear anywhere around the stoma, but it is more frequent in the lateral quadrants; it complicates about 5% of cutaneous stomas. Small hernias are usually well tolerated, but large hernias can be severely disabling when standing and on effort, and can prevent correct positioning of external urine collection appliances. The authors propose a repair technique for larger parastomal hernias via a semicircular incision around the stoma and interposition of an allogeneic mesh prosthesis.
