• Assess short term outcome of posterior component separation technique(PCS) including the regain of the physiological function of the abdominal wall.
• Detect most common post operative complications related to AWR techniques in a 6 months duration after operation.

posterior component separation(PCS) is one of the surgical techniques used in abdominal wall reconstruction plan foe management of relatively complex ventral hernia ,which cannot be treated with the conventional surgical way.

With or without transverses abdominis release(TAR) technique, (PCS) became widely accepted as surgical technique specially for large sized hernia defect, previous multiple laparotomies or unhealth abdominal soft tissue.

This study has a primary outcome which is detection of recurrence rate in patients under went posterior component separation technique in a period of 6 month after operation.

Inclusion Criteria:

• patients with complex ventral hernia with contraindication to the conventional surgical therapy.

Exclusion Criteria:

1. patients with contraindication to long standing anesthesia.
2. patients with emergency hernia situation.
