Summary
This study reports the first clinical experience with laparo-endoscopic single-site (LESS) extraperitoneal radical prostatectomy, demonstrating its technical feasibility and oncologic safety for prostate cancer treatment.
Area of Science:
- Urology
- Surgical Oncology
- Minimally Invasive Surgery
Background:
- Laparo-endoscopic single-site surgery (LESS) offers a near scar-free approach, advancing minimally invasive techniques.
- Radical prostatectomy is a standard treatment for localized prostate cancer.
Observation:
- The first clinical case of LESS extraperitoneal radical prostatectomy was performed on a 74-year-old man with localized prostate cancer.
- The procedure utilized a single umbilical incision and specialized instrumentation, with no intra- or postoperative complications.
Findings:
- The operation was completed successfully with a total time of 290 minutes and minimal blood loss.
- Histopathology confirmed adenocarcinoma with negative surgical margins and a Gleason score of 7.
- The patient experienced good functional recovery with minimal incontinence two weeks post-surgery.
Implications:
- LESS extraperitoneal radical prostatectomy is technically feasible, though challenging, requiring specialized equipment.
- Oncologic outcomes were not compromised, suggesting potential for this technique in prostate cancer treatment.
- Further research is needed to evaluate long-term oncologic and functional results, and patient benefits compared to traditional methods.
