The basic procedure of retractive surgery includes: anesthesia, resection of the stoma, restoration of the continuity of the bowel after anastomosis, retraction of the connected anastomosed bowel into the abdominal cavity, and suturing of the wound layer by layer. In clinical practice, retractive surgery is mainly used for secondary surgical treatment of rectal malignant tumors. After successful general anesthesia, routine sterilization is required to remove the diseased scar tissue. Open surgery is routinely chosen, but minimally invasive laparoscopic surgery is also available. Firstly, the intestinal canal of the stoma needs to be resected and then the intestinal canal on both sides needs to be anastomosed. Finally, the anastomosed bowel is retracted into the abdominal cavity and then the wound is sutured layer by layer. Care should be taken to avoid any damage to the bowel during the procedure, and the abdominal cavity should be carefully explored to avoid localized adhesions. It is recommended to consult the general surgery department of a regular hospital for the procedure.
