Small bowel gas usually refers to a small bowel hernia, and small bowel hernia surgery is not considered major surgery. Usually a small bowel hernia is not a major surgery, it is a routine procedure in general surgery. However, it should not be taken too lightly in elderly patients with very serious underlying conditions, and adequate preoperative preparation and consultation and treatment with the relevant departments is essential. Surgery is generally not considered for children with small bowel hernias younger than one year of age for the time being, as many children heal on their own. In contrast, high hernia sac ligation is usually advocated for children with hernias over one year of age. Tension-free repair of the hernia is available for most adult hernia patients. Patients are advised to follow the doctor’s instructions and actively cooperate with the doctor after small bowel hernia surgery. Care should be taken on weekdays to avoid colds and keep the bowels clear.
