Panniculectomy is surgery to remove a large apron of excess skin and fat that hangs from the lower abdomen, known as a pannus. It is mainly performed to improve problems with hygiene, repeated skin irritation, discomfort or reduced mobility rather than as a weight-loss procedure.
The procedure may be considered after major weight loss or when excess abdominal tissue causes ongoing functional problems. Before surgery, health conditions, smoking, body weight, nutrition and medications may need to be assessed because factors such as obesity, diabetes and smoking can increase the risk of complications.
Recovery generally involves wound care, activity restrictions and, in some cases, temporary surgical drains or compression garments. Possible complications include bleeding, fluid buildup, infection, poor wound healing and blood clots, and medical assessment is important if symptoms such as worsening redness, fever, unusual drainage, chest pain or shortness of breath develop after surgery.
What is it for?
A panniculectomy is performed to remove excess abdominal skin and fatty tissue that hangs over the lower abdomen. The goal is generally to improve function and reduce problems caused by the abdominal pannus rather than to change body shape for cosmetic reasons.
The procedure may help when excess tissue contributes to:
-
Difficulty keeping the skin folds clean and dry
-
Repeated irritation or inflammation between skin folds
-
Skin ulcers or other persistent skin problems
-
Chronic discomfort or pain
-
Difficulty walking or performing normal activities because of the size of the pannus
In the United States, insurance coverage may depend on whether the procedure is considered medically necessary. Some Medicare coverage policies, for example, consider factors such as a pannus extending below the pubic area, persistent skin problems despite treatment, impaired hygiene or mobility, pain and photographic documentation. Specific requirements can vary between health plans and Medicare contractors.
Panniculectomy is not intended to be a weight-loss operation. People who have lost a large amount of weight may undergo the procedure after their weight has become stable.
How to prepare
Preparation for panniculectomy starts with an evaluation of overall health and factors that may affect healing or the risk of complications. The surgical team may request a medical assessment or laboratory tests and review current medications and supplements.
Smoking is an important consideration because active smoking has been associated with a higher risk of complications after panniculectomy. Smoking cessation may therefore be recommended before surgery.
Body weight is also evaluated. Studies involving patients undergoing panniculectomy have found that the risk of postoperative complications, particularly wound complications, increases as BMI rises. However, there is no single BMI cutoff that applies to every patient.
Diabetes should be appropriately managed before surgery because it can increase the risk of problems with wound healing. Nutritional status may also require assessment, especially after bariatric surgery, as nutritional deficiencies can interfere with recovery.
The surgeon may also give instructions about medications. Aspirin, certain anti-inflammatory medicines and some supplements may need to be avoided when they could increase bleeding risk, depending on the individual medical situation.
How panniculectomy is performed
Panniculectomy is performed under anesthesia. The exact surgical technique depends on the amount and location of excess tissue, previous scars and other individual factors.
A horizontal incision is usually made across the lower abdomen so that the surgeon can remove the excess skin and fatty tissue. In some cases, a vertical incision may also be needed when there is a large amount of excess tissue or when additional removal is required in the central abdomen.
The navel may need to be repositioned or removed in some surgical plans, although this is not necessary in every panniculectomy. The surgeon then closes the incisions after the excess tissue has been removed.
Temporary drains may be placed beneath the skin to remove blood or fluid that collects after surgery. Techniques used to reduce fluid accumulation and protect the wound may vary according to the surgical approach.
Recovery after panniculectomy
After panniculectomy, dressings are placed over the incisions. A compression garment may also be recommended to support the abdominal area during the healing period.
If surgical drains are used, they remain in place temporarily and require care until the surgeon determines that they can be removed. Follow-up appointments are important for monitoring the incision, removing drains when appropriate and identifying possible complications.
Healing generally takes several weeks, although the exact recovery period varies according to the extent of surgery, overall health and whether complications occur. Physical activity is gradually resumed according to the surgeon's instructions.
Worsening pain, fever or chills, spreading redness, pus or foul-smelling drainage, persistent bleeding or separation of the incision can indicate a postoperative problem and should be medically evaluated. One-sided painful leg swelling may indicate a blood clot, while chest pain, shortness of breath or coughing blood require urgent assessment.
Possible risks and complications
Panniculectomy is a major surgical procedure and can cause complications. Some of the most important include:
-
Bleeding or hematoma
-
Seroma, which is a collection of fluid beneath the skin
-
Infection
-
Poor wound healing or wound separation
-
Loss of skin tissue
-
Changes in sensation or numbness
-
Persistent pain
-
Unfavorable or noticeable scarring
-
Deep vein thrombosis
-
Pulmonary complications
Wound-related problems are among the most common concerns after panniculectomy. Research involving large groups of patients has shown that higher BMI is associated with a progressively higher rate of complications, particularly wound complications.
Smoking is another important risk factor. Studies have found that active smoking is associated with a higher likelihood of major complications and surgical-site infections.
Diabetes may also affect healing. Research has identified diabetes as an independent risk factor for wound separation after abdominal panniculectomy, which makes careful management of blood sugar and other health conditions important before surgery.
Panniculectomy vs. tummy tuck
Panniculectomy and a tummy tuck, also known as abdominoplasty, both involve abdominal surgery, but they have different goals.
A panniculectomy primarily removes the hanging apron of excess skin and fat that can interfere with hygiene, mobility or daily activities. It does not necessarily involve tightening the abdominal muscles.
Abdominoplasty is generally performed to improve abdominal contour. In addition to removing skin and fat, it may involve tightening the abdominal muscles and repositioning the navel.
Studies comparing the procedures have found higher early complication rates among people undergoing functional panniculectomy than among those undergoing cosmetic abdominoplasty. However, panniculectomy patients often have more underlying health conditions, so complication rates cannot be directly compared without considering differences between the patient groups.
Results and scarring
The main expected result of panniculectomy is removal of the hanging abdominal pannus. This can improve hygiene and mobility and reduce problems caused by excess skin folds.
Scarring is expected because the procedure requires a large incision across the lower abdomen. The size and shape of the scar depend on the amount of tissue removed and the surgical technique used. Some people may also have a vertical scar if a vertical incision is required.
Scars change as healing progresses, but unfavorable scarring can occur. Wound-healing complications may also affect the final appearance of the scar, and some patients may eventually require revision procedures.
