• Laparosopic
– transperitoneal / extraperitoneal
– robot assisted
– antegrade / retrograde
– not nerve sparing / nerve sparing

Nerve-Sparing ELRP
Indication for Nerve-Sparing:
• Low-risk cancer– PSA ≤ 10 ng/ml– T ≤ 2– G ≤ 2– Gleason sum ≤ 7
• Preoperative potency• Patient‘s decision

Why positive surgical margins ?
Factors that might influence the incidence ofpositive surgical margins in nerve-sparing prostatectomy (I)
• Staging error:
clinical vs. pathological staging and grading
• Patient selection (indication?)
• Cancer volume and topography
• Volume of specimen in relation to patient’s pelvis

Positive surgical margins
Factors: why PSM ? (II)
• Obliteration of dissection plane
due to previous core biopsies
• Prostatitis and Periprostatitis
• Previous TUR-P transurethral resection of prostate
• Neoadjuvant antiandrogen therapy

Positive surgical margins
Factors: why PSM ? (III)
• Technique of haemostasis: - Increased insufflation pressure
- Local haemostatics
- Bipolar
- Clips
- Suture-ligature
• Availability of intraoperative frozen sections (IFS)
analysis
• Location of intraoperative frozen sections

Positive surgical margins
Factors: why PSM ? (IV)

Surgical Technique
• Laparoscopic extraperitoneal radical prostatectomy in an
antegrade cauterless technique
• Five port technique
• Pelvic lymphadenectomy if
– PSA ≥10 ng/ml or
– Gleason score ≥7
• Cauterless Intrafascial preparation (Veil of Aphrodite)
• Vesicourethral anastomosis with 8 2x0 vicryl sutures UR6

Positive margins and potency outcome after nerve-sparing laparoscopic prostatectomy
Keypoints of the cauterless technique
• No cautery and ultrasonic shears after bladder neck
exposure
• Exposure of seminal vesicles and prostatic pedicles first
• Preservation of tissue ventral to the rectum
• Prostatic vessels are clipped tangentially
at capsule level
• Suture ligatures (5x0) for arterial bleedings

Positive surgical margins
• Other recent series: – PSM in lap. prostatectomy: 4.4% - 35%
• Our series:– T2 tumors:
• 4.8% in NNS• 8.0% in NS
– T3 Tumors:• 22,7 % (5/22) in NNS• 100 % (4/4) in NS prostatectomy

Positive surgical margins
significantly higher risk for PSM when NS in T3-tumors
! consider organ-confined T2 tumors for NS only !

Conclusion
cauterless NS vs. NNS
higher rate of PSM difference significant only for T3-Tumors
CAVE: Understaging !
promising early potency raterecovery can take up to 2 years! longterm follow-up required
