If the patient’s rectal cancer is located very low and cannot be preserved, the anus, or descending perineum, needs to be removed. After the removal of the anus, there is a wound in the perineum for a short period of time, and the pain may be more obvious. Because the wound is relatively large and needs to be stitched up, some patients may have tension in the wound, and the patient may experience wound pain. It is also possible that the perineal wound may become infected, showing redness, swelling, pain, and even localized pus, which requires antibiotic infusion and anti-infection treatment, as well as strengthening the perineal wound dressing change. Patients with anal wounds of course have an enterostomy in the lower left abdomen, and the stoma requires enhanced care in the early stage. In the hospital, nurses can help change the medication and instruct the patient’s family to take care of the stoma of the wound. After the patient is discharged from the hospital, the patient himself and his family need to strengthen the care to prevent redness and swelling around the stoma, eczema-like changes in the skin, etc.
