Fixation-free incisional hernia repair in the elderly: our experience with a tentacle-shaped implant

Tentacle Mesh for Fixation-Free Spigelian Hernia Repair: Mini-Invasive Approach Granting Broad Defect Overlap

BACKGROUND

Compared to other types of abdominal protrusions, Spigelian hernias are not very common. In prosthetic repair of abdominal protrusions, mesh fixation and defect overlap are an open issue, as they are a source of complications. A newly developed tentacle-shaped mesh has been used to ensure a fixation-free repair with a broader defect overlap in the repair of abdominal hernias. This study describes the long-term results of a fixation-free repair of Spigelian hernias carried out with a tentacle mesh.

METHODS

A proprietary mesh composed of a central body with integrated radiating arms was used for repairing Spigelian hernias in 54 patients. The implant was positioned in preperitoneal sublay, and the straps were delivered across the abdominal musculature with a needle passer, and then, after fascia closure, cut short in the subcutaneous layer.

RESULTS

The friction of the straps passing through the abdominal wall served to hold the mesh in place, guaranteeing a wide overlap over the defect without fixation. In a long-term follow-up of 6 to 84 months (mean 64 months), a very low rate of complications occurred, but no recurrence was reported.

CONCLUSIONS

The tentacle strap system of the prosthesis allowed for an easy, fast and safe fixation-free placement granting a wide overlap, avoiding intraoperative complications. Greatly reduced pain and a negligible amount of postoperative complications characterized the postoperative outcome.

Tentacle-shaped mesh for fixation-free repair of umbilical hernias

Purpose

Mesh fixation and broad overlap represent an open issue in umbilical hernia repair. A proprietary-designed implant with tentacle straps at its boundary has been developed to ensure a suture-free repair and a broader coverage of the abdominal wall. The study describes the results of umbilical hernia procedures carried out with the tentacle-shaped implant and the related surgical technique.

Methods

A proprietary tentacle-shaped flat mesh having a central body with integrated radiating arms at its edge was used to repair large umbilical hernias in 62 patients. The implant was placed in preperitoneal sublay. The friction of the straps, crossing the abdominal wall thanks to a special needle passer, was intended to assure adequate grip to hold the implant in place assuring a fixation-free procedure and broad overlap of the hernia defect.

Results

In a mean follow-up of 48 months (range 10–62 months), 4 seromas and 2 ischemia of the navel skin occurred. No infections, hematomas, chronic pain, mesh dislocation, or recurrence has been reported.

Conclusions

The tentacle strap system of the prosthesis effectively ensured an easier implant placement avoiding the need for suturing the mesh. 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.
