ABSTRACT

Purpose:

In the search of a new material to repair duodenal wounds, a trial was conducted to assess the behavior of human amniotic membrane in the repair of the duodenal wall in rats.

METHODS:

Fifty Wistar rats weighing between 250 and 350g, male, were submitted to duodenotomy and randomly distributed into two groups. Group A (n=8) had no treatment and was used as the control group. In Group B (n=42) the duodenal wound was treated with a patch of human amniotic membrane.

RESULTS:

All animals in Group A died. In Group B no changes were observed with regards to death or the formation of duodenal fistula. All animals presented peritoneal adherences in the region on the duodenal wall repair and intestinal obstruction was observed in two animals. Healing of the duodenal wall in the region of the patch took place progressively as the post-operatory period increased, with regeneration of the mucosa and of the smooth muscle layer.

CONCLUSION:

From the clinical standpoint, the amniotic membrane proved to be a biological tissue which served as a temporary seal and allowed the wound to heal by second-intention, with re-establishment of the duodenal wall structure.
RESUMO

OBJETIVO:

Na busca de um novo material para o reparo dos ferimentos duodenais, foi efetuado um estudo para avaliar o comportamento da membrana amniótica humana no reparo da parede duodenal em ratos.

MÉTODOS:

Foram utilizados 50 ratos Wistar, com peso entre 250 e 350g, machos, distribuídos, aleatoriamente, em dois grupos. Grupo A (n=8), submetido à duodenotomia sem tratamento, utilizados como controle. Grupo B (n=42), submetido a um remendo de membrana amniótica humana para tratamento de ferimento duodenal provocado.

RESULTADOS:

Todos os animais do grupo A foram a óbito. No grupo B não foram observadas alterações quanto a óbito ou formação de fístula duodenal. Observaram-se em todos os animais aderências peritoneais à região do reparo da parede do duodeno e obstrução intestinal em dois animais. O reparo da parede duodenal na área do remendo ocorreu de maneira progressiva com o aumento do período pós-operatório, com regeneração da mucosa e da camada muscular.

CONCLUSÃO:

A análise da membrana amniótica, do ponto de vista clínico, mostrou ser um tecido biológico que serviu para selar.
