Hernias, commonly known as “small intestine gas”, are formed when intestinal tubes or fatty tissues in the abdominal cavity protrude into the weak tissues of the abdominal wall, usually in the inguinal region, around the umbilicus and at surgical incisions, and manifest as a mass in the inguinal region or even in the upper scrotum. It appears when coughing or straining, and disappears when lying down or pressing with the hand. In fact, what the people call hernia is mainly inguinal hernia, because inguinal hernia accounts for more than 90% of hernias, and the onset of hernia is more common in children and elderly people, and most of them are male patients.
