Background And Objective:
The deep inferior epigastric artery perforator (DIEP) flap was first described by Koshima and Soeda in 1989 and is now well-established as the gold standard in breast reconstruction. Lately, this issue has been explored in the context of head and neck reconstruction, highlighting growing interest in the use of the DIEP flap beyond breast reconstruction, but its usage in other anatomical regions appears elusive. Nevertheless, DIEP flap reconstruction may be a viable choice for complex, three-dimensional head and neck deformities while upholding the criteria of minimal donor site morbidity, according to a recent review. To determine whether the DIEP flap may be used successfully in other types of reconstruction, we conducted a review on the use, applications, and outcomes of the DIEP flap in non-breast reconstruction. This is, as far as we are aware, the first comprehensive analysis of all applications of the DIEP flap other than for breast reconstruction.
Methods:
A literature review was performed using PubMed to include all relevant articles in English or French published up to February 2022. Keywords included "DIEP flap" and "deep inferior epigastric perforator flap".
Key Contents And Findings:
A total of 1,299 articles were identified with 105 on the use of the DIEP flap in non-breast reconstruction. This suggests increasing recognition of the DIEP flap as a feasible option for reconstruction of most anatomical regions, especially in lower limb and head and neck reconstruction, followed by gynecological reconstruction. The DIEP flap was also utilized in the reconstruction of upper limb, thigh and hip defects. Less commonly, it has been used for penoscrotal, groin, sternal, buttock and abdomen reconstruction.
Conclusions:
The scientific body of evidence showed the robustness and versatility of the DIEP flap in non-breast reconstruction, with its relative pros and cons at different anatomical regions.
