Hard lumps in the wound after laparoscopic surgery may be related to suture irritation, wound infection, scar hyperplasia and other conditions. 1. Suture irritation: After laparoscopic surgery, local suture is needed, and absorbable suture is usually used. If the patient is sensitive to the suture material, it may irritate the local tissues and cause inflammatory reaction, and hard lumps will be formed in this area. 2. Wound infection: If the wound is not thoroughly sterilized before the surgery or not well protected after the surgery, it may lead to secondary infection in the area, resulting in hard nodules in the wound area, which will be accompanied by pain, redness and swelling. 3. Keloid hyperplasia: If the patient belongs to the keloid constitution, due to the presence of wounds in the abdomen, keloid hyperplasia will be formed during the recovery process of the wound tissues, manifesting itself as purplish-red raised bumps. It is recommended that after laparoscopic surgery patients rest more, if you find any discomfort symptoms, you should consult a doctor in time.
