Introduction
A lipoma excision is a minor surgical procedure performed to remove a lipoma, which is a benign (non-cancerous) tumor made up of fat tissue. Lipomas are usually slow-growing, painless, and located just beneath the skin. They can occur anywhere on the body but are most commonly found on the neck, shoulders, back, abdomen, arms, and thighs. While lipomas generally do not pose a health risk, surgical removal may be recommended if the lump becomes painful, grows rapidly, causes cosmetic concerns, or presses against a nerve or surrounding tissues. The procedure is typically straightforward and provides a permanent solution, as lipomas rarely grow back once fully removed.

Surgical Procedure
The excision of a lipoma is most often performed as an outpatient procedure under local anesthesia, meaning the patient is awake but the area around the lipoma is completely numb.
Once the anesthesia has taken effect, the surgeon makes a small incision in the skin directly over the lipoma. The size of the incision depends on the size of the tumor. Using surgical instruments, the surgeon carefully separates the lipoma from the surrounding tissue. Lipomas are usually encapsulated, meaning they are contained within a thin fibrous capsule, which makes them relatively easy to shell out intact.
After the lipoma is removed, the surgeon may apply pressure to control any minor bleeding. The incision is then closed using sutures (stitches). Depending on the depth and size of the incision, the surgeon may use absorbable stitches beneath the skin and non-absorbable stitches on the surface, or surgical glue. A sterile dressing or bandage is applied to protect the wound.

Surgical Risks
Lipoma excision is a very safe and routine procedure, but like any surgery, it carries a small amount of risk. These include a mild allergic reaction to the local anesthetic, minor bleeding during or immediately after the procedure, and a slight risk of infection at the incision site.

General Complications
Common and usually temporary complications following a lipoma excision include:
– Mild pain, tenderness, or bruising around the surgical site, which typically subsides within a few days.
– Swelling in the area where the lipoma was removed.
– Scarring at the incision site. While surgeons make every effort to minimize scarring, a small, permanent scar will remain.

Rare but Serious Complications
Serious complications are exceedingly rare for this type of minor surgery but can include:
– Hematoma or seroma: A collection of blood or fluid under the skin that may cause swelling and require drainage.
– Nerve damage: If the lipoma was located near a major nerve, there is a small risk of temporary or permanent numbness or tingling in the area.
– Recurrence: In rare cases, if a small piece of the lipoma is left behind, it could slowly grow back.

Pre-operative Preparation
Preparation for a lipoma excision is minimal.
– Medical Evaluation: The doctor will examine the lump and may order an ultrasound or MRI if the lipoma is large, deep, or has unusual features to rule out other types of tumors.
– Medication Review: Patients should inform their doctor of any medications they are taking, especially blood thinners like aspirin or ibuprofen, which may need to be paused a few days before the procedure to reduce bleeding risks.
– Fasting is generally not required since the procedure uses local anesthesia.

Post-operative Care
Patients can typically go home immediately after the procedure. The local anesthesia will wear off after a few hours, at which point mild discomfort may begin. Over-the-counter pain relievers, such as acetaminophen, are usually sufficient to manage any pain.

Wound Care
– Keep the bandage clean and dry for the first 24 to 48 hours as instructed by the surgeon.
– After the initial period, you may be allowed to shower, but avoid soaking the wound in baths or swimming pools until it is fully healed.
– Change the dressing daily or as directed, and inspect the incision for signs of infection, such as increasing redness, warmth, swelling, or pus.
– If non-absorbable stitches were used, you will need to return to the clinic in 7 to 14 days to have them removed.

Diet
There are no dietary restrictions following a lipoma excision under local anesthesia. Patients can resume their normal diet immediately.

Post-discharge Notes
Recovery is usually very quick. Most patients can return to work and normal daily activities the following day.
– Avoid strenuous exercise, heavy lifting, or activities that stretch the skin around the incision site for 1 to 2 weeks to ensure proper healing and minimize scarring.
– Contact your doctor if you experience a fever, severe pain, excessive bleeding, or signs of infection at the wound site.
