Typically, the steps in umbilical hernia surgery include making an incision, retracting the hernia sac, repairing or placing a patch, and closing the incision. 1. Incision: Usually, the incision is made in the curved position of the umbilical hole. 2. Hernia sac retraction: if the hernia sac is removed for open surgery, the hernia contents are put back into the abdominal cavity; if the hernia sac is removed for laparoscopic surgery, the contents are separated and put back into the abdominal cavity, and those with hypertrophy of the round ligament of the liver are treated accordingly. 3. Repair or placement of patch: for open tissue repair, folded suture repair and closure of the defect can be done; for laparoscopic umbilical hernia repair, the patch can be placed in the abdominal cavity to cover the location of the stoma and fixed with a staple gun. 4. Close the incision: close the peritoneum and buttress the suture. Note that before umbilical hernia surgery, the patient should first cooperate with the doctor to do physical examination and necessary auxiliary examination to ensure that the indications for surgery are met.
