A reconstructive algorithm after thigh soft tissue sarcoma resection including predictors of free flap reconstruction

BACKGROUND: Reconstruction of defects of the thigh after oncologic resection plays a vital role in limb salvage. Our goal was to evaluate our institution\u27s experience on thigh sarcomas to develop evidence-based recommendations to guide the reconstructive surgeon, including factors that would predict the need for free flap reconstruction. METHODS: We reviewed all thigh defects requiring plastic surgeon reconstruction following sarcoma resection at our institution from 1997 to 2014. Patient demographics, comorbidities, multimodality therapies, and operative characteristics were analyzed. RESULTS: There were 159 thigh reconstructions. Reconstruction was achieved by primary closure (15%), skin graft (13%), local fasciocutaneous flap (8%), local muscle flap (31%), regional muscle flap (28%), or free flap (4%). For the proximal third of the thigh, the most common flaps were pedicled thigh muscle and rectus abdominis flaps; for the middle third of the thigh, it was pedicled thigh muscle flaps; and for the distal third, it was pedicled gastrocnemius muscle flaps. Factors shown to be predictive of requiring a free flap included wide defects (p = 0.03) and location in the middle third of the thigh (p = 0.001). CONCLUSION: There are multiple options for reconstructing defects from thigh STS. When primary closure and skin grafts are not an option, most defects can be closed with pedicled local or regional muscle or fasciocutaneous flaps. Free flap reconstruction is rarely required but can be necessary when defects are wide or located in the middle third of the thigh

Complications after thigh sarcoma resection.

BACKGROUND AND OBJECTIVES: Standard treatment for extremity sarcoma is limb-sparing surgery often with radiation, but complications occur frequently. We sought to determine factors predictive of wound complications after thigh sarcoma resection and reconstruction while analyzing trends over time. METHODS: We reviewed all thigh defects requiring plastic surgeon reconstruction following sarcoma resection at our institution from 1997 to 2014. Patient demographics, comorbidities, operative characteristics, multi-modality therapies, and complications were analyzed. Wound complications were: infection, dehiscence, seroma, hematoma, or partial/total flap loss. RESULTS: There were 159 thigh reconstructions followed for 30 months on average. Eighty-seven percent of patients underwent radiation and 42% had chemotherapy. Almost half (49.1%) had a complication. The most common wound complication was surgical site infection (23.3%) followed by dehiscence (19.5%), and seroma (10.7%). Less common were partial (2.5%) or total flap loss (0.6%). Reoperation was required in 21 patients (13.2%). Tobacco use, older patient age, cardiac disease, and higher body mass index were independently associated with wound complications. Complications trended towards decreasing over time, but this was not statistically significant. CONCLUSIONS: Tobacco use, cardiac disease, and higher body mass index, but not the timing of reconstruction, appear to increase the risk of wound complications after thigh soft tissue sarcomas resection and plastic surgery reconstruction
