We recently repaired a giant lumbar hernia and had a rare postoperative complication of delayed presentation of the loss of domain and ultimately managed it uneventfully.
We have some expeience in this area; we always performed laparoscopic repair. The trick to avoid loss of domain is to suture the 'defect' before meshplasty. Please refer our article:

Although Laproscopic Repair is preferred currently, however result of the onlay mesh repair with open surgery are also very excellent. We performed 5 cases during last 7 cases, and to date no recurrence is reported.
