[Obturator hernia. Clinical principles and integrated classifications]

The author report a case of asymptomatic obturator hernia and describes anatomical, physiopathological and clinical principles relative to this condition. An integrated, personal classification is proposed: obturator hernias are divided in relation to development, descent degree of the sac, anatomical connections, clinical evolution. Early diagnosis and surgical treatment are very important to permit better chance of patient survival: intestinal occlusion and strangulation often occur.
