Background and Objectives A clear surgical margin is crucial for preventing the recurrence of soft tissue sarcomas (STSs). Recognizing the tumor border is difficult when the STS is impalpable or ill‐defined. Ultrasonography (US) is a widely used diagnostic device that can visualize certain tumors intraoperatively. However, its usefulness for intraoperatively assessing STSs is unclear and was investigated here. Methods Our study comprised 19 patients with STSs that were impalpable, ill‐defined, or beneath the fascia. All patients underwent intraoperative US (IOUS), with follow‐up times ranging from 5 to 103 months (mean, 49 months). Results The mean age of the study participants was 56 years (range, 25‐83 months). The most common histological diagnosis was undifferentiated pleomorphic sarcoma (UPS) (nine patients). The mean tumor size was 51 mm (range, 7‐126 mm). According to the residual tumor classification, 18 tumors were microscopically negative (R0), including seven close to the fascia, and one was microscopically positive (R1). Local recurrence occurred in two cases (both classified as R0). The recurrence‐free survival rate was 88.9% in 5 years. Conclusions IOUS‐guided surgery is useful for visualizing STSs. Using this technique, STSs can be precisely localized, evaluated, and excised.
