Abdominoplasty is a surgical procedure that restores a flat abdomen by removing excess skin and fat, while also tightening the abdominal wall muscles. It is performed under general anesthesia through an incision in the lower abdomen. After removal of excess tissues and muscle repair, the skin flap is pulled down and sutured with several internal layers and a cosmetic external stitch (or dermal glue for the scar).
One possible postoperative issue is a seroma — the accumulation of lymphatic fluid under the skin. This usually occurs in the early recovery period and can cause discomfort and concern.
Why Does Seroma Occur?
A seroma forms when small lymphatic vessels are disrupted. During abdominoplasty, a large skin flap is separated from underlying tissues, which creates conditions for fluid accumulation.
Normally, serous fluid leaks into the cavity, and fibrin within it aids in healing. The fluid should be reabsorbed, but due to tissue swelling, mild inflammation, or incomplete adhesion of tissues, it may accumulate and form a seroma.
The risk is higher when abdominoplasty is combined with liposuction, as this can further delay fluid resorption.
Is Seroma Dangerous?
Seroma itself is not considered a dangerous complication, but if prolonged, it can slow healing and even cause skin laxity in the operated area. Patients with obesity, diabetes, or impaired wound healing are at greater risk.
Small seromas (10–30 ml) usually resolve on their own within a few weeks. In other cases, fluid may need to be removed with a needle aspiration (puncture), and sometimes drainage tubes are used.
Diagnosis and Treatment
Seroma can be diagnosed with ultrasound (US), which detects fluid pockets under the skin. This examination is often recommended 5–7 days after surgery.
If fluid persists, repeat aspirations may be performed, allowing for faster healing and smoother recovery.
Prevention of Seroma
To reduce the risk of seroma, surgeons often use additional techniques that promote closer adherence of tissues during the operation. Patient compliance during recovery is also critical:
- wearing compression garments for up to 2 months,
- limiting physical activity,
- undergoing physiotherapy (ultrasound, lymphatic drainage, magnetotherapy, hyperbaric oxygen, etc.).
These measures lower the likelihood of fluid accumulation and support safe, even healing.
