RESUMO
The ability to close biopsy sites primarily without the need for removing sutures is obvious. However, it was unclear whether absorbable sutures could be used for this purpose. We prospectively studied 10 healthy volunteers on whom one 3 mm punch biopsy was performed on each arm. In each subject two sutures were compared for closure of the biopsy sites, polyglactin 910 and nylon. Our primary goal was to compare absorbable and nonabsorbable sutures in the closure of punch biopsy sites. Each site was closed with one simple percutaneous suture. The sites were evaluated at 2 weeks and 6 months for redness, infection, dehiscence, scar hypertrophy, and patient satisfaction. We found no statistically significant difference between the two suture materials in any of the above parameters. Therefore we conclude that absorbable sutures are a good alternative in the primary closure of skin biopsy sites.
