Postoperative seroma formation after abdominoplasty with placement of continuous infusion local anesthetic pain pump.

The most common complication after abdominoplasty is seroma formation. The incidence of seroma formation in abdominal procedures as a whole, including abdominoplasty, panniculectomy and transverse rectus abdominis myocutaneous flap abdominal donor sites, ranges from 1% to 38%. A recent concern among surgeons is the possibility of a causal relationship between the use of continuous infusion devices such as local anesthetic pain pumps and the development of seromas. A case of postoperative, persistent, recurrent seroma formation after abdominoplasty with the use of continuous infusion local anesthetic pain pump is presented. After several attempts at aspiration and drain catheter placement, only open surgical excision of the seroma cavity was found to be definitively effective in treating the development of seroma.
