Disease Description Hernia is an ancient and common disease, commonly known as “small intestine gas” or “hernia”, which can occur in both men and women, young and old. The vast majority of hernias occur in the abdominal wall and are caused by a weakness in the abdominal wall tissue, resulting in the protrusion of intra-abdominal organs (e.g., small intestine) from the weakness and the formation of a mass on the abdominal wall. The most common hernia is inguinal hernia, where the protruding mass occurs in the groin and sometimes into the scrotum; umbilical hernia, where the protruding mass occurs around the umbilicus; incisional hernia, where there is a history of surgery and the protruding mass is often at the site of the original surgical incision; and parastomal hernia, where the protruding mass is next to the stoma and often combined with the outward bulging of the stoma, making it difficult to attach the stoma bag. Diagnosis Based on the medical history, careful physical examination by a specialist, combined with ultrasound examination, a clear diagnosis can be made. For some complex incisional hernias and parastomal hernias, further combination with CT examination is required. Surgery is the only reliable treatment for hernia. As the saying goes, “if a small hole is not mended, a big hole is difficult to mend”, so surgery should be performed as soon as possible to avoid serious complications such as intestinal perforation and peritonitis due to hernia entrapment and strangulation. Surgical treatment is divided into tissue-to-tissue tension suture repair and mesh tension-free repair, and currently mesh tension-free hernia repair is the gold standard procedure for all kinds of hernia repair, including open and laparoscopic procedures.
