Purpose:
With the inception of laparoscopic ventral hernia repair came a novel device not used in conventional hernia repair; the spiral tack. We conducted an experimental study on pigs to determine whether spiral tacks contribute to adhesion formation.
Methods:
Using a standard laparoscopic technique in pigs, pieces of polypropylene mesh were fixed to the fascia on the upper abdominal wall, with polypropylene sutures on a randomly chosen side (side 1), and with 5-mm spiral tacks on the opposite side (side 2). The extent, type, and tenacity of the adhesions were assessed on postoperative days (PODs) 30 and 90.
Results:
The mesh fixed to the abdominal wall with spiral tacks tended to increase the extent, type, and tenacity of adhesions more than the mesh fixed with polypropylene sutures (P < 0.05).
Conclusions:
Spiral tacks contributed to the formation of adhesions more than polypropylene mesh did. Although this was a small-scale animal study, our findings suggest that the effect of spiral tacks used in laparoscopic ventral hernia repair should be assessed and the consequences monitored more closely.
