Flap-Based Breast Reconstruction: DIEP and Other Tissue Options

Flap-based breast reconstruction rebuilds a breast using your own skin and fat, moved from another part of your body. The best known version is the DIEP flap, which uses tissue from the lower tummy. It isn’t the only option, though. Tissue can also come from your back, thighs or buttocks, and the right choice depends on your body, your health and your cancer treatment.

If you’re weighing this up, you probably have practical questions about what the surgery involves. Here’s what each option involves, who it tends to suit, and what recovery looks like.

Quick Answer

• A “flap” is a section of skin, fat and sometimes muscle used to build a new breast. DIEP takes skin and fat from the lower abdomen, but no muscle.
• DIEP is a major surgery. It usually means a hospital stay of 5–10 days.
• You’ll have a hip-to-hip scar on your tummy, and the area will feel tight at first. A flatter tummy is a common side effect, but not a promise.
• Other flaps (TRAM, back, thigh and buttock) exist for people who aren’t suited to DIEP.
• Not every surgeon offers every flap, so ask early.

What is Flap-Based Breast Reconstruction?

Surgeons call it flap or “autologous” reconstruction, which simply means using your own tissue. It can be done at the same time as a mastectomy or months or years later. Our page on immediate or delayed reconstruction explains how to weigh up timing.

Two terms come up a lot:

• Free flap: the tissue is fully detached from its original blood supply, then moved to your chest. A “pedicle” flap, by contrast, stays attached to its blood supply.
• Microsurgery: surgeons use an operating microscope to reconnect tiny blood vessels from the donor site to vessels in your chest. That restores blood flow so the new breast tissue stays healthy.

DIEP is a free flap. So are the thigh and buttock options below.

How Does a DIEP Flap Work?

DIEP stands for deep inferior epigastric perforator. That’s the name of the small blood vessels that feed the tissue. The surgeon separates skin and fat from your lower tummy, leaves the abdominal muscles in place, and moves the tissue to your chest. The tissue taken is similar to what’s removed in a tummy tuck.

Before surgery, you’ll usually have a CT angiogram. It’s a scan that maps the blood vessels in your tummy wall so the surgeon can pick the best ones.

Is DIEP Flap Surgery a Major Surgery?

Yes. You’re under general anaesthetic for a long operation, because there are two surgical sites (chest and tummy) and delicate blood vessel work. Having both breasts done takes longer again. Expect a prolonged recovery, not a quick procedure.

Will My Stomach Be Flat After a DIEP Flap?

Often flatter, but that’s a side effect of the surgery, not its goal. Because the donor tissue is like a tummy tuck, many women find that their lower abdomen looks tighter.

Results vary from person to person. Our flap-based reconstruction results gallery shows real examples, and your surgeon can talk through what’s realistic for your body.

What’s Recovery Like After a DIEP Flap?

• Hospital checks: nurses check the new breast every 30–60 minutes for about the first day, to make sure blood flow is good. It makes sleeping hard, but it’s how problems get caught quickly.
• Drains: thin tubes placed under the skin that remove excess fluid from your chest and tummy. They usually come out 2–8 days after surgery.
• Lifting and driving: avoid lifting more than 10 kg (e.g., large washing baskets, boxes, small children) for at least 6 weeks, and possibly up to 3 months. Driving may be restricted too, especially in a manual car.

Complications can stretch recovery out. Your surgical team will give you specific guidance for your situation.

Why Might I Need a Second Operation?

Many women have a smaller touch-up procedure after the first surgery. It might be to even up the shape, improve symmetry or rebuild a nipple.

This is often around six months later, once swelling has settled. Some surgeons use fat grafting touch-ups to fine-tune contour. Ask your surgeon what to plan for.

Other Flap Options: Which One Suits?

If a DIEP flap isn’t suitable, there are alternatives. Your surgeon decides which is best suited to you.

TRAM Flap (lower tummy, with muscle)

This takes skin, fat and some abdominal muscle. It may be considered when tummy tissue is the best match, but a DIEP isn’t workable.

Back Flap (latissimus dorsi, or LD)

This moves skin, fat and muscle from your back. An implant is usually added to reach the right size. It’s often considered when there isn’t enough tummy tissue.

Thigh Flaps (TUG and PAP)

TUG uses tissue from the upper inner thigh. PAP uses tissue from the back of the upper thigh. They may suit someone with enough thigh tissue who can’t use their tummy.

Buttock Flaps (SGAP and IGAP)

These take fat and skin from the upper or lower buttocks. They’re another route when the tummy isn’t an option.

Who Might Not Be Suited to a Flap?

A flap may not suit you if you smoke, have diabetes, connective tissue disease or vascular disease, have had major abdominal surgery, or have a higher BMI.

Flaps are often considered for people who’ve had radiation therapy or who don’t have enough skin to cover an implant. If an implant is more your style, see our comparison of implants vs flap-based reconstruction.

Will Every Surgeon Offer Every Flap?

No. Not all types of reconstruction are offered by all surgeons or available at all facilities, particularly certain tissue flap options. So ask your surgeon which flaps they perform regularly, and how often.
