[Experience with the s-GAP flap for autologous breast reconstruction]. / Der Stellenwert der s-GAP-Lappenplastik in der Brustrekonstruktion - Ein Erfahrungsbericht.

In breast reconstruction with autologous tissue the DIEP flap has become the gold standard in recent years. The superior gluteal artery perforator (s-GAP) flap is an alternative harvested from the buttock. We present our experience with the s-GAP flap and discuss its role in breast reconstruction. All s-GAP flaps performed for breast reconstruction in the Department of Plastic and Hand Surgery, Behandlungszentrum Vogtareuth from June 2002 until February 2007 were retrospectively analysed. Out of 59 flaps 4 flaps failed, the success rate was 94 %. Partial or fat necrosis occurred in 2 cases. The s-GAP flap served as a safe reconstructive alternative to the DIEP flap. Advantages of the s-GAP flap are reliable perforators, the safe vascular supply and the firm fat structure which facilitates the breast reconstruction. The donor site morbidity is minimal, the gluteal muscles stay intact and the scar is easy to hide in the underwear. Disadvantages are a demanding preparation with a prolonged operating time compared to the DIEP flap. The s-GAP flap is a reliable and safe option for autologeous breast reconstruction. It is the method of choice for staged bilateral breast reconstruction or if the DIEP flap is not available, particularly in the thin patient.
