“…Another question arises whether the cutaneous lymphatic flow insufficiency could have an effect on sentinel lymph node mapping. Lopez-Prior demonstrated in a clinical trial that previous breast surgery (including aesthetic) did not have a significant effect on mapping the sentinel lymph node [7]. No papers on the correlation of postoperative or post-traumatic scars in limb sentinel lymph node mapping were found.…”

A b s t r a c tIntroduction: The constantly rising number of skin malignancies and increasing cancer awareness encourage more people to visit outpatient clinics in order to have various skin lesions removed. Despite the fact that scarring is a physiological response to any excision procedure, minimizing the size of it is a goal of every good practitioner. Therefore the question arises whether different techniques used to remove skin lesions may impact the formation and quality of skin scars. Aim: To perform an evaluation of skin scars formed by laser and surgical incisions and their influence on lymphatic outflow in rats. Material and methods: Five male rats were used. Using methylene blue, the migration of dye through lymphatic channels of the lower extremity was measured. Afterwards, transverse incisions were made distally using laser and a surgical blade. Wounds were left to heal by secondary intention. After 4 weeks dye migration assessment was repeated and tissue samples were obtained for microscopic evaluation. Results: Wounds after surgical incisions healed entirely. Wounds after laser treatment had not healed, with a visible area of granulation tissue and hair loss. Significantly worse dye migration was observed in rat extremities after laser therapy than after surgical incision (p = 0.007). Conclusions:The results of the study show that the size of the scar can depend on the incision technique used. Larger scars after laser therapy limit the lymphatic flow of the skin, which may have an adverse effect on mapping sentinel lymph nodes. However, this hypothesis requires further research.
