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.

Bowel or colon perforation is a rare but serious complication, which should always be kept in mind as a suspicion of acute abdomen in a female patient of reproductive age and with a history of intermittent gastrointestinal symptoms.

Background: Endometriosis is the presence of endometrial glands or viable stroma outside the uterine cavity, which affects approximately 2-10% of women of reproductive age 1. Pelvic structures, including the bowel, are commonly affected. Perforation of the colon by endometriosis is very rare and represents a surgical emergency. Clinical case: A 28-year-old female patient with abdominal pain in the right iliac fossa and pelvic cavity, fever and nausea, exploratory laparotomy is performed with the discovery of sigmoid perforation of the colon, requiring resection of the lesion and terminal colostomy, finding as definitive diagnosis endometriosis. Conclusion: Bowel or colon perforation is a rare but serious complication, which should always be kept in mind as a suspicion of acute abdomen in a female patient of reproductive age and with a history of intermittent gastrointestinal symptoms.
