An easily reversible hernia refers to an extra-abdominal hernia in which the contents of the hernia can be easily retracted into the abdominal cavity and is relatively easy to treat. Hernia, in which an organ or tissue in the body leaves its normal anatomical position and enters another part of the body through a congenital or acquired weakness, defect or foramen. There are more types of extra-abdominal hernias, which can be categorized as easy-to-recover hernia, difficult-to-recover hernia, incarcerated hernia and strangulated hernia. In the case of easy-to-recover hernia, when the patient stands, walks, and infants and children cry, due to a sudden increase in intra-abdominal pressure, the contents of the hernia will be protruded into the hernia sac, and in the case of lying down, relatively quiet or sleep, the contents of the hernia can be returned to the abdominal cavity, and the abnormality can not be observed on the surface of the body. Except for umbilical and inguinal hernias in infants less than 1 year of age, which may heal spontaneously, other easily recurring hernias require prompt admission to the hospital for surgical treatment.
