An obturator hernia is a rare cause of bowel obstruction. Due to its narrow passage in the obturator canal, these are more susceptible to becoming incarcerated and subsequently strangulated. Due to its challenging detection, obturator hernia is often diagnosed late. A 75-year-old thin-built female with COPD presented to the emergency room with symptoms of abdominal obstruction. Abdominal examination revealed distension, firmness, rigidity, and tenderness with no bowel sounds. An erect abdominal X-ray showed multiple air-fluid levels, indicating an acute abdomen due to intestinal obstruction. Emergency exploratory laparotomy revealed an obturator hernia with strangulated ileum and perforation, necessitating resection and double barrel ileostomy. Unfortunately, despite all medical interventions, the patient succumbed to hospital-acquired pneumonia following the surgery. Obturator hernia, known as 'the skinny old woman hernia,' is rarely externally visible or palpable, leading to frequent undiagnosed cases. It presents with bowel obstruction or perforation and carries the highest morbidity among abdominal hernias. Timely intervention is crucial to prevent complications like bowel strangulation. This case report highlights the challenges of diagnosing and managing obturator hernia, a rare condition with significant morbidity. Early detection through imaging or operative findings is crucial to prevent complications like bowel strangulation, especially in older women at higher risk.
