Umbilical hernia can cause pain, especially during incarceration and strangulation. Generally, umbilical hernias are caused by factors such as pregnancy, excessive omental fat, chronic coughing, and severe constipation. A sudden increase in abdominal pressure may lead to the incarceration of the omentum or intestines, causing significant pain and hardening of the hernial mass. In such cases, emergency surgery may be necessary. For adults, traditional tissue repair or open tension-free hernia repair is generally chosen, while minimally invasive treatment options may be selected for specific groups. In children, umbilical hernias are typically observed conservatively, and if the umbilical ring remains larger than 1.5cm after the age of two, surgery should be considered.
