How can lymphocele development be prevented after laparoscopic radical prostatectomy?

Area of Science:

• Urology
• Surgical Oncology
• Minimally Invasive Surgery

Background:

• Lymphocele development is a common complication following pelvic lymph node dissection (PLND) in laparoscopic radical prostatectomy (LRP).
• Effective prevention strategies are crucial for improving postoperative outcomes in patients undergoing LRP.

Purpose of the Study:

• To evaluate the efficacy of a vessel-sealing device (VSD) in preventing lymphocele formation after LRP with PLND.
• To compare lymphocele development rates between conventional PLND techniques and those using VSD.

Main Methods:

• A prospective study enrolled 120 patients undergoing LRP with PLND.
• Patients were randomized into two groups: conventional PLND (Group 1) and VSD-assisted PLND (Group 2).
• Postoperative computed tomography (CT) scans assessed lymphocele size at 1 month.

Main Results:

• No significant difference in overall lymphocele rates between groups.
• However, the incidence of significant lymphoceles (>1500 mm²) was substantially lower in the VSD group (4/60) compared to the conventional group (16/60) (p<0.01).
• Multivariate analysis identified VSD as the sole independent factor for preventing large lymphoceles (OR=4.96, p<0.01).

Conclusions:

• Vessel-sealing devices are effective in preventing the development of large lymphoceles during LRP with PLND.
• Utilizing VSD represents a significant advancement in reducing major postoperative complications associated with PLND.
