Summary
This study introduces a novel technique for laparoscopic radical prostatectomy that avoids electrocautery, clips, and adhesives. Utilizing bulldog clamps and cold cutting preserves neurovascular bundles (NVBs) and arterial blood flow during prostate surgery.
Area of Science:
- Urology
- Surgical Techniques
- Minimally Invasive Surgery
Background:
- Traditional laparoscopic radical prostatectomy often employs electrocautery, thermal energy, clips, or bioadhesives for pedicle control.
- These methods carry potential risks of thermal injury and complications affecting neurovascular bundles (NVBs).
Purpose of the Study:
- To present a novel technique for lateral pedicle control during laparoscopic radical prostatectomy.
- The technique aims to completely eliminate the use of electrocautery, ultrasonic thermal energy, clips, and bioadhesives.
Main Methods:
- A nerve-sparing laparoscopic radical prostatectomy technique was applied in 25 patients.
- Lateral prostate pedicles were transiently controlled using atraumatic vascular bulldog clamps.
- Pedicles were divided by cold cutting, with NVBs preserved through meticulous dissection and hemostasis achieved via 4-0 Vicryl suturing.
- Real-time transrectal ultrasound monitored arterial blood flow in NVBs.
Main Results:
- Mean bulldog clamp time was approximately 11 minutes per pedicle.
- Transrectal ultrasonography confirmed sustained arterial blood flow within NVBs during clamping.
- A statistically significant reduction in visible blood vessels within NVBs was observed during and after clamping (P <0.001).
- One patient (4%) experienced positive surgical margins; potency and continence data are pending.
Conclusions:
- A technique for lateral pedicle ligation in laparoscopic radical prostatectomy using monitored cold cutting and suturing was successfully described.
- This method completely avoids electrocautery, thermal energy, clips, and bioadhesives.
- Bulldog clamp application did not interrupt arterial blood flow within the NVBs, suggesting potential for improved functional outcomes.
