RESUMEN
INTRODUCTION: Spiegel hernia is an infrequent type of abdominal wall defect. Traditionally, it was repaired with an open technique, currently we have multiple laparoscopic techniques with the use of prosthetic material. CLINICAL CASE: We present two cases of Spiegel hernia, one patient scheduled electively and one patient of urgency due to incarcerated hernia, both diagnosed pre-surgically with abdominal tomography. DISCUSSION: Both patients were successfully operated laparoscopically with intraperitoneal onlay mesh technique using composite mesh and articulated fixation system. CONCLUSION: This technique is shown as a recommended option due to its technical facility, good results, both for elective surgeries and emergency surgeries.
INTRODUCCIÓN: La hernia de Spiegel es un tipo infrecuente de defecto de la pared abdominal. Tradicionalmente se realizaba su reparación con técnica abierta, pero en la actualidad contamos con múltiples técnicas laparoscópicas con uso de material protésico. CASO CLÍNICO: Presentamos dos casos de hernia de Spiegel, un paciente programado de manera electiva y otro de urgencia por hernia incarcerada, ambos diagnosticados de manera prequirúrgica con tomografía abdominal. DISCUSIÓN: Los dos pacientes fueron intervenidos de manera exitosa por vía laparoscópica con técnica de malla intraperitoneal utilizando malla compuesta y sistema de fijación articulado. CONCLUSIONES: Esta técnica se muestra como una opción recomendable por su facilidad de realización y buenos resultados, tanto para cirugías electivas como para cirugías de urgencia.

Androgen effects, mediated by the androgen receptor, regulate important cellular processes such as growth, proliferation, and differentiation. The presence of androgen receptor has been described in structures of the central nervous system, mainly in advanced fetuses, newborns, and adult animals. This study describes the presence and location of androgen receptor in early developmental stages of the nervous system. The androgen receptor mRNA was evidenced through reverse transcriptase-PCR and the androgen receptor protein by immunohistochemistry and western blot techniques in the cerebral vesicles of 9.5-day mouse embryos and chicken embryos at stages 8-17 of Hamburger and Hamilton. The androgen receptor protein was located in the nucleus of neuroepithelial cells throughout the neural tube.
