Parammary glands are common confined lumps in the armpit, and surgery is required for large, painful, or suspicious nodules. However, any surgery has certain surgical risks, and so does the surgery of the parametrial gland, the specific risks are as follows: 1. Infection: Infection may occur in parametrial surgery, once it occurs, you should seek medical attention; 2. Hematoma: The occurrence of hematoma is related to the damage to the blood vessels during surgery, which can subside within a short time after surgery; 3. 4. Incomplete excision: The gland is not found to be the source of the gland when it is excised during surgery, resulting in unclear gland excision, once this happens, it needs to be treated by surgery again; 5. Bilateral asymmetry: The operator should pay attention to bilateral symmetry during preoperative design; for bilateral asymmetric parastomal breast, the amount of excised gland and skin should be adjusted according to the size and skin laxity of the parastomal breast; 6. The amount of skin left on the surface when removing the gland is not the same. Therefore, in order to avoid the above risks, care should be taken. Pressure bandages are needed after surgery to prevent severe edema. Also pay attention to ensure the hygiene and cleanliness of the wound after surgery to prevent infection and inflammation.
