There is no superior treatment for an existing parastomal hernia. Several methods have been tested and used such as stoma relocation, sutures to narrow the opening in the fascia and abdominal wall and fixation and closure of the lateral space but none has proven to prevent from recurrence of herniation. Mesh repair has been shown to give a lower recurrence rate 0-33%. No technical factor, such as site of stoma formation (through or lateral to rectus abdominis muscle), related to the construction of the stoma was proven to prevent hernia formation.
