Radical Prostatectomy

The LigaSure™ vessel sealing system is a unique energy-based ligation method. Complete hemostasis is achieved by reforming the collagen and elastin in vessel walls to form an autologous seal. The following are vessels typically within the recommended vessel sealing range (up to and including 7 mm in diameter), that can be sealed with the LigaSure™ system.

• Pubo prostate ligaments
• Dorsal vein complex
• Prostatovesical
• Inferior vesical
• Capsular branches
• Apical branches
• Endopelvic fascia

The ability to seal large vessels quickly and effectively, combined with an associated decrease in needle passes on the operating field, suggest benefits directly associated with the use of the electrothermal vessel sealing system. Perhaps a more promising finding lies in the shorter duration associated with the inflammatory response. The potential for seals composed of the patient’s native tissue to reduce the inflammatory response may translate to a decrease in post-surgical adhesions. Clinical studies are currently in progress to quantify the relationship between seals made with the LigaSure™ vessel sealing system and the incidence of post-surgical adhesions.
