2 Shape the Future of Urological Surgery THE ROLE OF LAPAROSCOPIC SURGERY IN NEW MILENNIUM Victor Chia-Hsiang Lin, MD Division of Urology, Department of Surgery Chi-Mei Medical Center

3 MY TALK TODAY IS Minimal Invasiveness in Urological Surgery Endoluminal & Percutaneous & Extraluminal (Laparoscopy) Real Impact of Laparoscopic Surgery on Urology Be the standard of care? The Realm of Laparoscopic S. In Urology Practice patterns in CCF Chi-Mei Experience The Future? Miniaturization Robotic surgery & Telesurgery Endoluminal reconstruction

4 Trend In Urological Surgery Big surgeons make a big wound?? Minimal Invasiveness Less analgesics Better cosmesis Shorter hospital stay Quicker convalescence

5 Minimal Invasiveness in Urology This trend is like Industrial Revolution, like Digital Revolution

6 TERRITORY of UROLOGICAL DISEASE Endoluminal Disease: Most urolithiasis,, benign obstructive stricture, BPH, superficial TCC, Extraluminal Disease: Adrenal tumor, renal cortex tumor, retroperitoneal tumor, whatever outer than urethra and transitional cell epithelial lining

7 Trend In Urological Surgery: MIS 3 main Strategies from 3 Revolutions: Endoluminal Endoscopic surgery (1960) Percutaneous Manipulation (1970) Extraluminal Endoscopic Surgery (1990) (Lap. S.)

39 If the difficulty is the only excuse of reluctance to laparoscopic radical nephrectomy, laparoscopic radical nephrectomy will be the treatment of choice in the near future!!

63 Conclusion Purely laparoscopic Nx and NxUx as efficacious as HAL in experienced hand offer the advantages flexible choice of wound for specimen extraction ergonomic less cost (without hand-port TM relatively earlier recovery TM ) However, HAL is still essential for neophyte laparoscopists to go through the learning curve

64 Laparoscopic Radical Nephroureterectomy with Concomitant Radical Cystectomy for Multi-focal Transitional Cell Carcinoma in Uremic Patients Annual Meeting, 19 th Taiwan Surgical Association, March 2005

65 Drawbacks of traditional open surgery in uremic patients Extremely long incision Increased morbidity Difficulty in postoperative care Prolong postoperative recovery

66 Case 1 64 y/o, male ESRD under hemodialysis Left ureteral TCC (T1) s/p laparoscopic NxUx + BCx for 3 years (retroperitoneal hand-assisted) assisted) Recurrent bladder TCC (high grade, T2a) s/p TUR-BT Suspicious right renal tumor

67 Laparoscopic left NxUx + radical cystoprostatectomy Operation time: 260 min Estimated blood loss: 200 ml Post-OP hospital stay: 3 days

68 Laparoscopic left NxUx + radical cystoprostatectomy

69 Case 2 64 y/o, male Hemodialysis for 5 years PSVT s/p RF ablation, ASA III Left ureter TCC (T3) s/p laparoscopic NxUx + BCx for 0.5 years (pure trnasperitoneal) Reccrrent bladder TCC s/p TUR-BT (grade II, T1)

71 Transitional cell carcinoma, right ureter (T3) Transitional cell carcinoma, urinary bladder (T2)

72 Vaginal Delivery of Specimen

73 Conclusion Laparoscopic nephroureterectomy and concomitant radical cystectomy is a minimally alternate for multifocal TCC in uremic patients.

74 Laparoscopic Radical Prostatectomy - Initial Experience Annual Meeting, 19th Taiwan Surgical Association, March 2005

75 Rationale of LRP Introduction Minimally Invasiveness under laparoscopic magnification Equivalent oncological control, urine continence and sexual function preservation Pioneering LRP 1997 Schuessler: : 9 pt; 9.4 hrs; 3 complications 1997 Raboy: : 1 case report of Retroperitoneal RP 1999 Guillonneau and Abbou: : the first 2 largest series with promising results

76 Material and Methods From March 2004 to January 2005 Total 12 patients who were diagnosed as clinically localized prostate cancer underwent transperitoneal LRP The preoperative demographic data and the postoperative outcomes and functional results (continence and sexual function) were analyzed.

77 Operative data Mean OP time: 418 mins ( ) Mean estimated blood loss: 204 cc ( cc) Blood transfusion: Nil Neurovascular bundle preservation: 8 pts Rt: : 3 Lt: 3 Bil: : 2 Bilateral pelvic node dissection: 2 due to high PSA (13.57 and 15.3 ng/ml) Conversion to open surgery: Nil

78 Results Oncological control: Organ confined : 11, Extracapsular extension with negative surgical margin: 1 Serum PSA all fell below 0.2 ng/ml Continence: no one need pad protection Sexual preservation: 5 (70%) regained erection 3 (43%) achieved satisfactory vaginal penetration

79 Ultimate Challenge?? 69 y/o male. PSA: 18 ng/ml ct1c Huge prostate gland (165 gm) with intravesical protrusion Provide LRP or not?? Annual Meeting, 19th Taiwan Surgical Association, March 2005

80 Critical Procedures

81 Conclusion Our preliminary results suggest LRP can be performed safely and effectively. Is LRP easier than Open RP due to laparoscopic magnification after learning curve? We believe that LRP will hold promising in Taiwan in the near future.

82 What Can NOT Be Done Laparoscopically In 2005? 1st Tier Diagnostic laparoscopy UDT Renal cyst 2nd Tier Adrenalectomy Simple, Radical Nx,, NU+BCE, Live DNx Pyeloplasty 3rd Tier Ileal ureter Augmentation cystoplasty Partial Nx Radical prostatectomy Radical cystectomy with ileal conduit, continent pouch, or neobladder Medical contraindication Severe intraabdominal adhesion (No working space) Bulky tumor with local or node infiltration Tumor size??

84 MINIATURIATION NEEDLESCOPIC

85 Mini Minimal Invasiveness Needlescopic vs. Conventional Laparoscopy Traditional Laparoscopic Adrenalectomy ( 6 mos post-op ) Needlescopic Adrenalectomy ( 2 wks post-op )

89 From Lab to Clinical More Investigations Endoluminal plastic technique (e.g. endopyeloplasty) (e.g. endoluminal ureteroplasty)

90 Fire Continues between Lap. S and Open S. The easier open procedures have obviously been overtaken by MIS The remainings for open S. are the disease with extensive adhesion, complicated reconstruction, huge tumor Open Surgery Laparoscopic S. Endourol. S. Continue to raise the bar? Nerve-sparing radical cystectomy with orthotopic bladder substitute
