| Sumario: | Introducción: Una de las causas del fracaso del cierre primario de la pared abdominal en pacientes con gastrosquisis es la perivisceritis que impide la reintroducción de las asas intestinales. El recambio de líquido amniótico trata de eliminar los productos que ocasiona la perivisceritis. Casos Clínicos: Caso 1: se realizó 2 recambios de líquido amniótico, se obtiene producto con gas- trosquisis y sin perivisceritis. Cierre primario de la pared abdominal sin tensión, sin ampliar orificio y preservación del cordón. Caso 2: se realizó 3 recambios, se obtiene producto con gastrosquisis y sin perivisceritis. Cierre primario de la pared abdominal sin tensión, sin ampliar orificio y preservación del cordón.
Conclusiones: Con el recambio del líquido amniótico se pretende disminuir o eliminar el grado de perivisceritis y así facilitar el cierre primario de la pared abdominal y disminuir las complicaciones de un cierre en etapas.
Abstract: Introduction: One of the causes of failure of primary closure of the abdominal wall in patients with gastroschisis is perivisceritis, which impedes reintroduction of the intestine. Amniotic fluid exchange tries to eliminate products that cause perivisceritis. Clinical cases: Case 1: Two amniotic fluid exchanges were carried out. A newborn with gastroschi- sis and without perivisceritis was delivered. Primary abdominal wall closure was performed without tension, without increasing the wall defect, and preserving the umbilical cord. Case 2: Three amniotic fluid exchanges were carried out. A newborn with gastroschisis and without perivisceritis was delivered. Primary abdominal wall closure was performed without tension, without increasing the wall defect, and preserving the umbilical cord. Conclusions: The purpose of amniotic fluid exchange is to minimize or eliminate perivisceritis and thus facilitate primary closure of the abdominal wall and decreasing complications of a staged closure.
