Reconstruction of massive oncologic defects using free fillet flaps.

Area of Science:

• Surgical Oncology
• Reconstructive Surgery
• Limb Amputation Reconstruction

Background:

• Forequarter and hind-limb amputations are utilized for curative and palliative treatment of proximal limb, thoracic, or truncal malignancies.
• Large defects resulting from these amputations often necessitate free flap reconstruction.
• Fillet flaps, harvested from the distal portions of amputated limbs, serve as a 'spare parts' solution for reconstruction.

Purpose of the Study:

• To evaluate the efficacy and outcomes of immediate reconstruction using free fillet extremity flaps.
• To assess the oncological safety and complication rates associated with this reconstructive technique.
• To determine the impact of fillet flaps on patient quality of life post-amputation.

Main Methods:

• Retrospective review of 27 patients undergoing immediate reconstruction with free fillet extremity flaps (1991-2008).
• Analysis of patient demographics, preoperative treatments (radiotherapy and chemotherapy), and resection types (hemipelvectomies, forequarter, and hindquarter amputations).
• Evaluation of flap survival, wound healing, complication rates, oncological outcomes, and patient survival.

Main Results:

• All 27 free fillet flaps survived, and all wounds healed successfully.
• A 15% complication rate was observed, including partial flap necrosis and vascular compromise.
• While 30% of patients were alive at study end (mean follow-up 14 months), the mean survival was 7 months; no flap recurrences were noted, and pain/necrosis/infection improved.

Conclusions:

• Free fillet flaps are oncologically sound for reconstruction after major limb amputations.
• The technique offers a solution without donor site morbidity and with an acceptable complication rate.
• Fillet flap reconstruction facilitates wound healing and improves the quality of life for affected patients.
