Robotic-Assisted Retroperitoneal Sarcoma Resection with Left Renal Vein Reconstruction with Bovine Pericardium

Area of Science:

• Urology
• Surgical Oncology
• Robotic Surgery

Background:

• Retroperitoneal soft-tissue tumors can be challenging to resect.
• Leiomyosarcoma is a rare malignancy arising from smooth muscle tissue.
• Preservation of renal function is critical during retroperitoneal tumor surgery.

Purpose of the Study:

• To demonstrate the technique for robotic-assisted resection of a left retroperitoneal leiomyosarcoma.
• To showcase the reconstruction of the left renal vein using a bovine pericardial patch.
• To highlight the feasibility of preserving renal function after major venous reconstruction.

Main Methods:

• Robotic-assisted surgery using the DaVinci Xi system.
• Excision of leiomyosarcoma with adequate surgical margins.
• Reconstruction of the left renal vein with a bovine pericardial patch and Gore-Tex suture.
• Management of vascular control and ischemia time.

Main Results:

• Complete resection of the leiomyosarcoma with negative surgical margins.
• Successful reconstruction of the left renal vein.
• Uneventful postoperative recovery with discharge on postoperative day 2.
• No change in postoperative renal function.

Conclusions:

• Robotic-assisted surgery enables complete resection of retroperitoneal leiomyosarcomas.
• Left renal vein reconstruction with a bovine pericardial patch is effective in preserving renal function.
• This approach offers a viable option for managing complex retroperitoneal tumors.
