Cosmetic result of lower midline laparotomy wounds: polybutester and nylon skin suture in a randomized clinical trial.

Abstract

OBJECTIVE:

To compare the cosmetic outcome of lower midline laparotomy scars using either nylon or polybutester suture for skin closure.

METHODS:

A randomized clinical trial compared polybutester skin suture with 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 were assessed in all patients at 18 months following surgery and compared by nonparametric statistical tests.

RESULTS:

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 laparotomy scar showed an inferior cosmetic result compared with the upper part underneath the umbilicus for scar hypertrophy, scar width, and the total scar score.

CONCLUSIONS:

Polybutester skin suture diminishes the risk of hypertrophic scarring because of its special properties allowing it to adapt to changing tensions in the wound. Increased closure tension of the skin in the midline region above the pubic bone may be caused by a relative immobility of the skin. Scar cosmetics in this area may be improved by extra subcuticular suture support.
