Key result
Laparoscopic resection safely removes a 7-cm retroperitoneal liposarcoma without perioperative complications.
Why the study?
The safety, feasibility, and minimal invasiveness of laparoscopic resection for retroperitoneal tumors, including liposarcomas, needed to be demonstrated.
Case Report (n=1)
Laparoscopic resection of retroperitoneal liposarcoma appears safe, feasible, and minimally invasive in this case report.
May support laparoscopic feasibility in select cases; leaves open comparative oncologic outcomes versus open resection.
Here, we describe a case of a retroperitoneal liposarcoma successfully managed by laparoscopic surgery. A 72-year-old man underwent abnormal hypertension screening using computed tomography (CT), which revealed a low-density mass measuring 7 cm in diameter in the retroperitoneal space. We diagnosed the mass as a liposarcoma before the operation. The mass was resected laparoscopically. No perioperative complications were encountered, and the patient was discharged on the fourth postoperative day. The pathologic diagnosis was well-differentiated liposarcoma, indicating complete surgical resection. Thus, we conclude that a laparoscopic approach for the patients with retroperitoneal tumors, including liposarcomas, is safe, feasible, and minimally invasive, even if there is a possibility of the tumor being malignant.

Nomura et al. (2013) conducted a case report in Retroperitoneal liposarcoma (n=1). Laparoscopic resection was evaluated on Surgical success and perioperative complications. Laparoscopic resection of a 7-cm retroperitoneal liposarcoma was performed safely with no perioperative complications and discharge on the fourth postoperative day.
