Evaluation of the donor site after liposuction with a syringe in rabbits Avaliação da zona doadora após lipoaspiração com seringa em coelhos

Abstract

PURPOSE: To evaluate the donor site of adipocytes as well as histopathological alterations secondary to liposuction. METHODS: All animals underwent liposuction with a syringe on the right side of the back. While the left side of the back was used as control and did not undergo intervention. The 10 rabbits were divided into two groups A and B according the postoperative day which were submitted to euthanasia: 90 and 120 days. All adipose tissue from the donor site was analyzed and compared with the control macroscopic and light microscopy. Tissues were weighed and analyzed searching for histological changes and late inflammatory response to trauma such as fibrosis, fat necrosis and inflammation and macrophage infiltration. RESULTS: There was wide variation in adipose tissue volume between the experimental and the control on macroscopic analysis. The presence of histopathological changes was found in two samples at 90 days. CONCLUSIONS: There was a relationship between the presence of fibrosis with the weight and number of days after liposuction surgery in rabbits. The study show macroscopic difference between control and experiment sides in all rabbits.OBJETIVO: Avaliar a zona doadora de adipócitos bem como as alterações histopatológicas secundárias a lipoaspiração. MÉTODOS: Todos os animais foram submetidos à lipoaspiração com seringa no lado direito do dorso. Enquanto o lado esquerdo do dorso foi usado como controle, não sofrendo intervenção. Os 10 coelhos foram divididos em dois grupos A e B conforme o dia pós-operatório (DPO) os quais foram submetidos à eutanásia: 90 DPO e 120 DPO. Todo tecido adiposo da zona doadora foi analisado e comparados com o controle macroscopicamente e à microscopia óptica. Os tecidos foram pesados e foram analisadas as variações histológicas em busca de uma resposta inflamatória tardia ao trauma como fibrose, inflamação, necrose gordurosa e infiltrado macrofágico. RESULTADOS: Foi observada grande variação de volume de tecido adiposo entre o experimento e o controle do dorso a macroscópica e a presença de alteração histopatológica em duas amostras aos 90 dias. CONCLUSÕES: Houve relação entre a presença de fibrose com o peso e numero de dias pós-operatório na lipoaspiração de coelhos. O estudo mostrou diferença entre os lados experimento e controle em todos os coelhos.
