Long-Term Results of Fixation-Free Incisional Hernia Repair Using a Tentacle-Shaped Implant.

INTRODUCTION
The fixation and the overlap of the mesh represent an open issue in incisional hernia repair. An exclusively designed prosthesis has been developed to assure a suture-free repair and a broader coverage of the abdominal wall. This study describes the long-term results of incisional hernia procedures carried out positioning a tentacle-shaped implant through a specifically developed surgical technique.


MATERIALS AND METHODS
A proprietary symmetrically-shaped flat mesh constituted by a large central body with integrated radiating arms was used to repair incisional hernias in 68 patients. The prosthesis was placed in preperitoneal/retromuscular sublay. The friction of the straps passing through myotendineal structures of the abdomen was intended to assure an adequate grip to firmly hold the device in place with a broad overlap of the hernia defect in a fixation-free fashion. All tentacle straps were positioned through a special needle passer crossing the abdominal wall laterally from the defect borders then cut short in the subcutaneous layer.


RESULTS
In a long-term follow-up of 12 to 96 months (mean 58 months), 11 seromas occurred. No infections, hematomas, chronic pain, mesh dislocation, or recurrence have been reported.


CONCLUSIONS
The tentacle strap system of the prosthesis effectively ensured reduced skin incision and an easier implant placement avoiding the need for suturing the mesh. Regularly performed computed tomography (CT) and ultrasound (US) investigations proved that the arms of the implant ensured a proper orientation and stabilization of the mesh in association with a broad defect overlap. The specifically developed surgical procedure showed a quick postoperative recovery, a very low complication rate, and no recurrences, even in the long-term.
