    Abstract:
    An obturator hernia is an infrequent but significant cause of intestinal obstruction. The incidence of obturator hernias is between 0.05 and 1.4% of all hernias. The mortality rate can be as high as 70% when acutely incarcerated due to the difficulty in diagnosis and delay in surgical treatment Three progressive stages of obturator herniation have been classified and can be one of three different varieties depending on the pathway the herniated sac follows. Knowledge of the anatomy and pathogenesis of obturator herniation is essential in diagnosis and treatment. The most common clinical presentation is intestinal obstruction (90%) and this is often seen in elderly, emaciated, multiparous women with predisposing conditions. Other classic signs, though not always present include obturator neuralgia, the Howship-Romberg sign and the Hannington-Kiff sign. Computed tomography scan is the most favored diagnostic imaging method. The abdominal surgical approach is most preferred when a diagnosis is uncertain and laparoscopy should be employed in elective early surgeries. This aim of this article is to review the diagnosis and treatment of obturator hernia by describing the anatomy, embryology, clinical presentation, diagnosis, and management currently in use. Increased awareness and proper management of this condition will result in decreased morbidity and mortality.
