Surgical repair of parastomal hernia

Operative procedures used for repair of a parastomal hernia.
(A) Relocation of the stoma - high risk of failure.
(B) Direct repair of the fascial defect - high rate of recurrence.
(C) Subcutaneous mesh repair - low recurrence risk but undermining is a risk for ischemic injury to skin.
(D) Extraperitoneal mesh repair - most common approach for repair with lower failure rate.
