Extraperitoneal laparo-endoscopic single-site radical prostatectomy: first experience

Objectives

Up to now, laparo-endoscopic single-site surgery (LESS) represents the closest surgical technique to scar-free surgery. The objective of the study is to report the first clinical experience with a LESS endoscopic extraperitoneal radical prostatectomy.

Materials and methods

A 74-year-old man presented with a clinically localized prostate cancer (PSA 9.9, Gleason score 3 + 3 = 6). Consent was obtained for LESS radical prostatectomy. After a 2-cm midline subumbilical incision, the preperitoneal space was created using a balloon trocar. Then, the Triport? was introduced. Using straight, as well as pre-curved instruments, the radical prostatectomy was performed in accordance with the well-described technique of endoscopic extraperitoneal radical prostatectomy.

Results

The procedure was completed successfully. Overall operation time was 290 min. The estimated blood loss was 100 mL. There were no intra-or postoperative complications. No additional ports were required. On the 6th postoperative day, a cystogram was performed. No leak was demonstrated, enabling catheter removal. Histopathology revealed bilateral adenocarcinoma with no extracapsular extension and a Gleason sum of 3 + 4 = 7. Surgical margins were negative. Two weeks postoperatively, the patient reported the use of only one safety pad for continence.

Conclusions

An extraperitoneal laparo-endoscopic single-site radical prostatectomy is technically challenging but can be accomplished. A multi-instrument port and purpose-built equipment are mandatory. The oncologic outcome was not compromised. Additional short- and long-term studies are necessary to clarify the role of LESS in radical prostatectomy regarding the oncologic and functional outcome as well as the potential benefits like reduced tissue trauma and pain.
