The Anatomic Feasibility of a Functional Chimeric Flap in Complex Abdominal Wall Reconstruction

Contemporary Abdominal Wall Reconstruction: Emerging Techniques and Trends

Abdominal wall reconstruction is a common and necessary surgery, two factors that drive innovation. This review article examines recent developments in ventral hernia repair including primary fascial closure, mesh selection between biologic, permanent synthetic, and biosynthetic meshes, component separation, and functional abdominal wall reconstruction from a plastic surgery perspective, exploring the full range of hernia repair's own reconstructive ladder. New materials and techniques are examined to explore the ever-increasing options available to surgeons who work within the sphere of ventral hernia repair and provide updates for evolving trends in the field.

Subtotal Thigh Flap for Large Abdominal Wall Defect Reconstruction in Patient With Recurrent Dermatofibrosarcoma Protuberans: A Case Report and Literature Review

BACKGROUND

Harvesting an adequate-sized flap is challenging for reconstructing large defects on the abdominal wall. A subtotal thigh flap would be one of the choices as it provides a well-vascularized large flap with muscle components. Moreover, dermatofibrosarcoma protuberans (DFSP) is a low-grade dermal neoplasm with a high recurrence rate. There is still no consensus on the extent of resection to prevent a recurrence.

OBJECTIVES

We present a case of a patient who underwent the reconstruction of a large abdominal wall defect with a subtotal thigh flap after the resection of recurrent DFSP.

MATERIALS AND METHODS

A 59-year-old man killed from a recurrent huge mass in the lower abdomen with an invasion of the small intestine. His baseline characteristics and records of operations, medications, and outcomes were reviewed.

RESULT

After tumor excision, a 28 × 30-cm subtotal thigh flap was harvested from his left thigh to reconstruct the abdominal defect. A microvascular anastomosis with left deep inferior epigastric vessels was made eventually. The flap was in good condition, and the donor site was covered with a split-thickness skin graft.

CONCLUSIONS

Subtotal thigh flap may be considered for large abdominal wall defect reconstruction as it allows good perfusion of relatively large skin paddles compared with other free flaps. Also, patients with DFSP need definite margin-free resection and close follow-up to prevent a recurrence.
