Abstract

Background

In this study, we assessed the feasibility of laser-assisted tissue welding as a means of fixing mesh prostheses to the peritoneum. We then tested the initial tensile strength of the bonds.

Methods

Fresh porcine peritoneal coupons were lap-joint bonded with laser-activated solder. Anesthetized New Zealand white rabbits and Yorkshire pigs also underwent laparotomy. Vicryl mesh (2.0 × 1.0 cm) was attached to the peritoneum using a laser system (1.43 μ, 2.5 W, 60°C), solder formulations and configurations, and a 1 cm2 bond area. Control segments were affixed with 4.8-mm staples. After the animals were killed, the segments were excised en bloc. Tensile strength assessment was conducted by measuring peak force breaking strength.

Results

The strength of the solder bonds were similar in all groups (range, 261.5 ± 170.3-465.3 ± 288.2 g/cm2) and were not statistically different from the controls (215.8 ± 117.8 g/cm2).

Conclusions

These values are similar to the 200-500 g/cm2 acute strengths reported for sutured or stapled peritoneal closure. Mesh fixation by solder is feasible, and further development of this technology is warranted.
