Six Surgical Stages in the Resection of Primary Left Retroperitoneal Liposarcoma: A Standardized Comprehensive...

Area of Science:

• Surgical Oncology
• Gastrointestinal Surgery

Background:

• High-volume centers are crucial for retroperitoneal sarcoma (RPS) treatment.
• En bloc resection with adjacent organs is standard for RPS.
• A six-stage surgical approach is presented for left-sided RPS.

Purpose of the Study:

• To illustrate a standardized six-stage surgical approach for primary left-sided retroperitoneal liposarcoma.
• To demonstrate a reproducible and oncologically sound surgical technique.

Main Methods:

• A 73-year-old male with a 13-cm left retroperitoneal liposarcoma received neoadjuvant chemotherapy.
• En bloc resection of the tumor, ipsilateral kidney, adrenal gland, and colon was performed.
• The approach prioritized early vascular control and identification of critical structures, preserving the pancreas and spleen.

Main Results:

• The surgical team successfully resected the left retroperitoneal mass.
• A plane was identified between the tumor and the pancreatic tail, allowing for organ preservation.
• The psoas muscle was resected due to adherence, ensuring oncological clearance.

Conclusions:

• Resection of left-sided RPS is complex, requiring specialized surgical skills.
• The six-stage approach offers a reproducible and oncologically sound method for RPS resection.
• This technique adheres to the principles of surgical oncology for optimal patient outcomes.
