Abstract
Surgery remains mainstay modality of treatment of STS of extremity. In majority of patients, primary closure is possible following surgical resection of the tumor. Primary closure of wound may not be feasible in tumors with large area of skin involvement and sometimes following a whoops procedure. We analyzed postoperative complications and oncological outcomes in patients who underwent free flap reconstruction. Thirty-seven patients who required a free flap for reconstruction of the defect following resection of the STS were included in the study. There were 26 men and 11 women with a mean age of 40 years. Seventy-three percent tumors were in lower limb; 62% patients had undergone a whoops procedure elsewhere. Flaps were fasciocutaneous in 19, myocutaneous in 15, and free muscle transfers in 3 patients. Seventeen patients had early surgical site complications. Nine patients had early flap failures. Of the 9, 6 patients had total loss of flap and in 3 the flaps were salvaged. Two patients had partial loss (< 50% of total area) of flap. Four patients had edge necrosis and two had suture diastasis. Nine patients had late surgical site complications. Four had post-radiotherapy wound dehiscence. Late SSI was noted in two. Late joint contracture and chronic lymphedema was seen in one patient each. One died due to sepsis. Statistically significant association was not found between patient, tumor or treatment-related factors and complications or flap failures. Mean duration of surgery was 7.73 h. Twenty-three patients required multiple surgeries due to complications. Mean time to initiate adjuvant therapy from the date of surgery was 47 days. Mean OS of the group was 67 ± 7.3 months. Mean RFS was 58 ± 7.8 months. Single-stage free flap reconstruction following surgical resection of extremity sarcoma is a viable option of reconstruction while salvaging the limb. Though associated with high rate of early surgical site complications, they are manageable.
