Abstract:
A 20-year-old woman with a perineal alveolar soft part sarcoma was referred to our hospital. MRI showed that an irregular oval tumor occupied the perineum. The tumor was contiguous to the vagina, rectum, levator muscle, and pubis and was diagnosed as alveolar soft part sarcoma by transvaginal biopsy. Laparoscopy-assisted total pelvic exenteration combined with a pubic resection was performed, and an R0 resection with a wide margin was achieved. It is well known that only R0 resection improves the outcome of patients with localized alveolar soft part sarcoma. In this case, the perineal manipulation was difficult because the tumor was huge and had a rich blood flow. Massive bleeding occurred during the perineal manipulation. However, we kept the operative field dry thanks to minimal intraoperative blood loss during the laparoscopic phase. The laparoscopic approach might be advantageous for such a demanding surgical procedure for tumors in the distal pelvis and perineum.
