Polybutester suture has unique performance characteristics that may be advantageous
for wound closure.

This monofilament synthetic nonabsorbable suture exhibits
distinct differences in elongation compared with other sutures. With the polybutester
suture, low forces yield significantly greater elongation than that of the other sutures.
In addition, its elasticity is superior to that of other sutures, allowing the suture to
return to its original length once the load is removed. In a study by Trimbos et al.

they compared the cosmetic outcome of lower midline laparotomy scars using either
nylon or polybutester suture for skin closure. A randomized clinical trial compared
polybutester skin suture with that of nylon for lower midline laparotomy wounds in
50 women undergoing gynecologic surgery. Scar hypertrophy, scar width, scar color,
the presence of cross-hatching marks, and a total score was assessed in all patients at
18 months following surgery and compared by nonparametric statistical tests. The
wounds closed with polybutester suture were significantly less hypertrophic than
those closed with nylon. Regardless of the suture material used, the lower part of
the laparo-tomy scar showed an inferior cosmetic result compared with the upper
part underneath the umbilicus for scar hypertrophy, scar width, and the total scar
score. The surgeons concluded that polybutester skin suture diminished the risk of
