Abdominal Wall Transplant

The graft combines skin, muscle, fascia, blood vessels, and sometimes nerves because abdominal wall defects can involve several tissue layers at once. Replacing these components together supports restoration of the wall’s structural organization rather than addressing only its surface. This composite approach is particularly relevant when the defect cannot be adequately repaired with conventional reconstruction.

The donor graft depends on reconnection of its blood vessels to the recipient’s circulation. Surgeons establish these vascular connections so blood can reach the transplanted skin, muscle, fascia, and other included tissues. Successful circulation is therefore central to maintaining the graft as living tissue and enabling the reconstructed abdominal wall to provide protection for internal organs.

Because the abdominal wall graft comes from a donor, the recipient’s immune system may recognize its tissues as foreign. Immunosuppressive therapy limits this immune rejection and helps preserve the transplanted composite tissues. Its role is especially important because the graft contains several tissue types, including skin and muscle, that must remain viable for reconstruction to succeed.

This approach is considered when conventional mesh or flap reconstruction cannot adequately address a severe, complex, or nonreconstructable abdominal wall defect. The relevant clinical settings include extensive trauma, tumor removal, infection, and repeated abdominal surgery. In these circumstances, transplantation may provide both structural replacement and restoration of abdominal wall integrity when simpler reconstruction is unsuitable.

The procedure requires a donor abdominal wall graft containing the needed tissue layers, surgical connection of the graft’s blood vessels to the recipient’s circulation, and immunosuppressive treatment afterward. Together, these components address tissue replacement, graft perfusion, and immune control. The treatment is therefore not limited to reconstruction itself, but also includes maintaining the transplanted tissue.

Abdominal wall transplantation can restore the integrity of the abdominal wall and help protect internal organs when extensive tissue loss prevents conventional repair. Depending on the graft and clinical setting, it may also contribute to functional and structural reconstruction. These outcomes make the technique relevant for patients whose defects result from trauma, infection, cancer surgery, or repeated operations.

Severe abdominal disease or tissue loss may require reconstruction of both internal organs and the surrounding abdominal wall. In such cases, the abdominal wall graft can be transplanted alongside intestinal or multivisceral organs, providing structural coverage and reconstruction as part of a broader transplant strategy. This combined use addresses related internal and external abdominal defects in one clinical context.
