TGF-β expression on different suturing technique for abdominal skin wound closure in rats

Abstract

BackgroundThe method of closing the abdominal wall, as well as, the choice of material for stitching are important aspects of efficient incision closure. Generally, transforming growth factor-beta (TGF-β) is involved in the wound healing process. Suturing procedures also play a part in the wound dehiscence occurrence. This study aimed to compare TGF-β expressions in rats after using the large stitch vs. small stitch technique for abdominal skin wound closure. MethodsA total of twenty Wistar rats (Rattus norvegicus) were used in this experiment. Small tissue bites of 5 mm were obtained by the small stitch group and the large stitch group received large bites of 10 mm. Abdominal skin incisions were closed by running sutures. On days 4 and 7, the animals were euthanized. For TGF-β expressions, histological parts of the tissue-embedded sutures were analyzed. With significance set at p < 0.05, two-way ANOVA showed that on days 4 and 7, the TGF-β expressions of the rats in the small stitch group were nearly identical to those in the large stitch groups. ResultsAfter including twenty rats in this study, results showed the TGF-β expressions on days 4 and 7 in rats in the small stitch group were equivalent to those in the large stitch group. (p = 0.45). ConclusionsBetween the small and the large stitch groups, the TGF-β expressions are similar, suggesting that the suturing methods do not have any significantly different beneficial impact on the frequency of wound dehiscence.
