Well-differentiated liposarcoma is the second most common pathologic type of retroperitoneal sarcoma. It is characterized by a huge mass, but multiple organ invasions are common. Surgery is the only treatment option for potential cure. Hyper-accuracy three-dimensional (3D) reconstruction is widely used in robotic partly nephrectomy owing to its ability to visualize overlapping anatomy.
A 54-year-old man was admitted for progressive abdominal distension over the preceding 2 mo. Computed tomography revealed a 32 cm × 21 cm × 12 cm lipomatous mass. Hyper-accuracy 3D reconstruction was performed because of the complex relationship between the mass and nearby tissue. The patient underwent surgical resection, and the tumor did not recur for over 16 mo.
Hyper-accuracy 3D reconstruction is useful for operative planning owing to its intuitiveness and precise determination of anatomical structures in both tumors and nearby tissues.
Core Tip: Surgical resection is the preferred treatment for well-differentiated liposarcoma (WDLPS). Hyper-accuracy three-dimensional (3D) reconstruction is widely used in robotic partial nephrectomy for its ability to visualize overlapping anatomy. Here, we report a case of giant WDLPS in the retroperitoneum treated by surgical resection using hyper-accuracy 3D reconstruction. To the best of our knowledge, our case was the first to use this technique for giant retroperitoneal WDLPS. We expect our case to highlight the value of hyper-accuracy 3D reconstruction for complicated open surgery and provide a basis for retroperitoneal liposarcoma treatment.
