Hernias formed by the obturator tube of the peritoneum and abdominal organs are called obturator hernias. Obturator hernia is a type of pelvic hernia that is rarely seen clinically.

The closed-cell tube is 2 to 2.5 cm in length, and the direction of travel is forward, downward and inward, and it can accommodate a fingertip in diameter. The obturator tube has two inner and outer ports. The inner mouth is covered by peritoneum and extra-abdominal tissue; the outer mouth is obturator external muscle and pubic muscle. The obturator tube passes through obturator nerves and blood vessels. There are two main causes of obturator hernias: one is congenital factors, such as abnormal tissue development in the obturator canal and the mouth area, local tissue is weak, and the strength of the obturator canal is affected by nerve passage. ; The other type is acquired factors, such as middle and old women with multiple pregnancy history, due to significant increase in intra-abdominal pressure during delivery. In addition, various physiological and pathological reasons cause a long-term increase in intra-abdominal pressure and weight loss, and the disappearance of fat in the obturator tube is also one of the causes of obturator hernia.
