Case 1: An 83-year-old woman was admitted to our hospital complaining of abdominal pain and nausea. Contrast-enhanced abdominal computed tomography showed the small intestine trapped bilaterally between the pectineus muscle and external obturator muscles. An emergency operation was performed. It was found that the ileum was incarcerated through the left obturator foramen 30cm from the terminal ileum 30cm thereafter the ileum was incarcerated through the right obturator foramen. After the reduction of the incarcerations, both of the hernia hilia were closed with the ovarium. Case 2: A 79-year-old woman was admitted to our hospital complaining of nausea and right femoral pain. Contrast-enhanced abdominal computed tomography showed the small intestine was trapped bilaterally between the pectineus muscle and external obturator muscle. An emergency operation was performed. It was found that the ileum was incarcerated via the right obturator foramen 120cm from the terminal ileum and the ischemic ileum was resected. The left side of the incarcerated obturator hernia was resolved spontaneously. After the reduction of the incarceration, both of the hernia hilia were closed with a mesh plug via the extraperitoneal approach. Obturator hernia is sometimes encountered as a cause of intestinal obstruction. However, synchronous bilateral obturator hernias are rare.
