Small bowel hernia, the medical term for hernia, is classified as umbilical hernia, inguinal hernia, hiatal hernia, incisional hernia, surgical recurrent hernia, white line hernia, femoral hernia, etc. Simply put, a hernia is a tear or hole in the muscle tissue of the abdominal wall, through which the patient’s small intestine and other organs or tissues leave their original position and protrude into other parts of the body, just like a car tire, the outer tire is broken and the inner tire protrudes through the hole; it is mostly caused by coughing, sneezing, excessive force, excessive abdominal fat, forceful defecation, women’s pregnancy, excessive crying of children, degenerative changes in the strength of the abdominal wall in old age, etc. caused. When any tissue or organ in the body leaves its normal, inherent part and enters another part through a normal or abnormal weak or defective part or gap in the body, it is called a hernia. It is also commonly referred to as a hernia. Most hernias in the human body are found in the abdomen. This is because the abdominal cavity carries the thoracic cavity above and the lower extremities below. The abdominal cavity contains many major organs such as stomach, liver, intestine, kidney, pancreas and spleen as well as large blood vessels, which form several anatomical pores, weak and defective areas, giving a certain anatomical basis for the formation of hernia, so that when the trigger for hernia formation occurs, a hernia can be formed. This is the main reason why hernias mostly occur in the abdomen. Hernias in the abdomen are to be divided into two main categories. One category is hernias formed when organs or tissues (such as intestinal tubes) in the abdominal cavity protrude to the body surface through weak or defective parts of the abdominal wall or pelvis, etc., which is called extra-abdominal hernia; the other category is hernias formed when organs or tissues in the abdominal cavity enter abdominal orifices formed in the original or due to lesions or surgeries abnormally, which is called intra-abdominal hernia. In daily life, extra-abdominal hernia is the most common surgical disease, while intra-abdominal hernia occurs only in some special cases and is not common.
