Effects of Negative Pressure Wound Bandaging After Mastectomy

Participant information sheet: Mastectomy is a surgical method used to treat breast cancer. A mastectomy involves the removal of the entire breast. A common postoperative complication after a mastectomy is seroma, i.e. an abnormal accumulation of serous fluid in the wound cavity. At present, at Falun regional hospital, conventional dressings are used on the wound after the operation as well as an active drainage that is left in place for a couple of days. There is research that suggests that negative pressure dressings can promote wound healing and reduce the formation of seroma. The purpose of this study is to investigate whether negative pressure dressings reduce the risk of postoperative seroma compared to regular dressings. The investigators will also look at whether it reduces the risk of other postoperative complications such as infection, bleeding and wound healing problems. The
