Incision is Splitting in Center and Has a Yellow Pus Coming out - is This Normal?

First, I would contact your plastic surgeon for an appointment to have him/her examine the wound. It is very common to have an open area in the middle of your abdomen after surgery. You do want to make sure that it is not infected. Should no infection be present, then proper wound care should be discussed between you and your plastic surgeon.

I would consult your surgeon to rule out any infections. Signs of infection may include fever, chills, abnormal swelling, or redness around the incision. It is important that you follow all post-op instructions to avoid any complications. It is common for patients to experience superficial openings, which will heal over time. It is difficult to determine whether you would need re-suturing without current photos. Often these openings will heal with dressing changes. Scar revision may be helpful in the future to improve tge appearance of the scar.

On this site, I do my best to give advice without a physical examination but I want you to know that a physical examination by a board certified physician is always the best way to get the most accurate information.
