Reconstruction of Posterior Trunk Defects Following Sarcoma Excisions-A Dual-Center Experience

Area of Science:

• Oncology
• Plastic Surgery
• Reconstructive Surgery

Background:

• Posterior trunk sarcomas present unique challenges due to aggressive local invasion and proximity to vital structures.
• Reconstruction requires robust, well-vascularized tissue capable of withstanding radiotherapy and pressure.

Purpose of the Study:

• To evaluate the outcomes of flap reconstructions for soft-tissue sarcomas of the posterior trunk.
• To assess the efficacy and complication rates of various flap techniques in sarcoma management.

Main Methods:

• A 7-year retrospective analysis of 47 patients with posterior trunk sarcomas.
• Reconstruction methods included direct closure, skin grafts, and 39 flap reconstructions (myocutaneous, fasciocutaneous, muscle-only).

Main Results:

• No flap failures were recorded; 70% of patients healed without complications.
• Complications included seroma, dehiscence, infection, and partial flap necrosis, with no significant difference based on radiotherapy or patient factors.
• Radiotherapy increased complication rates in both preoperative and postoperative settings.

Conclusions:

• Fasciocutaneous and musculocutaneous flaps are suitable for posterior trunk sarcoma reconstruction.
• These flap techniques provide well-vascularized tissue crucial for managing radiotherapy and reducing morbidity in sarcoma patients.
