Recurrent and complex hernia management
When previous surgical repairs fail or massive abdominal wall defects develop, standard patching is no longer enough. We perform definitive Abdominal Wall Reconstruction (AWR) using robotic component separation to rebuild your core anatomy.
How we restore the abdominal wall
Instead of simply bridging a hole with synthetic mesh, Abdominal Wall Reconstruction releases tight muscular layers to close the gap naturally and reinforces it from behind.
Transversus abdominis release (TAR)
Releases the deepest muscle layer to medialise the rectus muscles, closing massive midline gaps tension-free while preserving anterior abdominal innervation and vascularity.
Enables closure of large defect widths (up to 15-20 cm) without chronic skin flaps.
Robotic retrorectus mesh placement
Positions large-format macroporous mesh outside the peritoneal cavity, behind the abdominal muscle layer. This completely isolates the prosthetic from bowel loops.
Prevents direct visceral adhesions, bowel erosion, and chronic mesh infection.
Preoperative volumetric optimization
Includes high-resolution CT volumetry, targeted chemical component relaxation (Botulinum toxin A), and respiratory prehabilitation to safely return herniated viscera.
Prevents postoperative abdominal compartment syndrome and respiratory splinting.
Fasciotens-assisted abdominal wall closure
For loss-of-domain defects where component separation alone cannot achieve tension-free midline closure, we apply continuous mechanical traction using the Fasciotens dynamic system. Adjustable lateral tension is applied preoperatively and intraoperatively to progressively lengthen and mobilize the abdominal wall, reducing the force required for final fascial approximation.
Reduces intraoperative closure tension and supports safe midline reconstruction in defects previously considered inoperable.
Standard repair vs. Abdominal wall reconstruction
Comparing conventional bridge techniques against comprehensive robotic retromuscular reconstruction.
| Evaluation parameter | Standard bridge repair | Robotic AWR (TAR / eTEP) |
|---|---|---|
| Surgical approach | Onlay or intraperitoneal (IPOM) mesh bridging | Robotic eTEP / TAR retrorectus anatomical reconstruction |
| Mesh position | In direct contact with bowel or under skin flaps | Completely extraperitoneal (behind muscles, outside peritoneum) |
| Abdominal wall function | Static bridge; abdominal core weakness persists | Dynamic restoration of linea alba and rectus contraction |
| Documented recurrence risk | 15% – 35% in complex incisional defects | < 3% in certified Centre of Excellence protocols |
| Post-op chronic pain rate | Higher due to transfascial fixation tacks | Minimal; tack-free sublay plane with physiologic tissue integration |
