Whether the condition of a patient with left inguinal hernia is serious or not should be objectively analyzed based on the size of the patient’s hernia sac, whether local impaction occurs and whether it is accompanied by obvious clinical symptoms: i. If the volume of the patient’s left inguinal hernia is relatively small, there is no local impaction of intestinal canal, omentum and other tissues, and there are no obvious clinical symptoms of pain and swelling, the condition of the patient’s left inguinal hernia is not serious. It is suggested that elective hernia repair surgery can be performed to effectively avoid serious complications such as ingrowth of hernia contents. If the volume of left inguinal hernia is larger, the organs in the abdominal cavity such as ileum, sigmoid colon and bladder repeatedly protrude through the abdominal wall defect, which will cause clinical symptoms such as chronic constipation, difficulty in urination and abdominal pain, and once the intestinal tube is embedded, it will cause ischemia and necrosis of the intestinal tube and induce serious complications such as infectious shock.
