Laparoscopic Radical Cystectomy in Catholic
University Experience

Introduction

Radical cystectomy the gold standard for M.
invasive or high risk bladder cancer
Laparoscopic surgery expanding now applied
to treat neoplasm of the pelvic organ Excellent
perioperative long-term results in RCC,
Prostate ca.

.
Encourage to explore the role of laparoscopy in
bladder ca.
.
3
To define the role of laparoscopic radical
cystectomy ?
  • The main problems to solve
  • Technical difficulty
  • Urinary diversion method
  • intracorporeally ? or
    extracorporeally ?
  • Oncologic risk , replicating the outcome of open
    surgery ?

.
To overcoming these problems, We would like to
share our experience with LRC in 36 cases, since
june 2003,
.

Pathogenesis
The steps of operations
Port placement


Camera port
Marking incision site for specimen removal
5-port fan-shaped transperitoneal approach
5
Mobilization division of the ureters
  • Important landmarks
  • Medial umbilical lig.
  • Vas
  • Rectovesical pouch
  • Iliac vessels
  • Incision of Peritoneum
  • dissection down to the
  • UVJ
  • isolation of ureter
  • as distally as possible
  • Frozen biopsy

.
.
6
Posterior dissection
  • Transverse peritoneotomy
  • at arch of douglas pouch
  • Developing plane Between
  • SV, prostate and the rectum
  • Denonvilliers fascia
  • Prerectal fat

.
.
7
Anterior dissection
  • Bladder is filled with saline
  • starting lateral to medial
  • umbilical lig.
  • divide urachus
  • the prevesical space is opened

.
.
8
Endopelvic fascia incision DVD control
  • Exposure of endopelvic fascia
  • Incision on line of reflection
  • Separation from the levator ani M.
  • Suture of DVC (3-0 PDS)

.
.
9
Lateral dissection
  • Retracting bladder medially
  • away to the ext. iliac V
  • Divide the vesical prostatic
  • fibrovascular pedicles
  • Sono-surg and Hem-o-lok clip

.
.
10
Apex dissection
  • divide the DVC expose urethra
  • To prevent contamination ,
  • occlude the urethra
  • divide the urethra posterior
  • attachment

.
.
11
Extended PLND
  • Ant. to Ext. iliac artery and
  • medial to genitofemoral N.
  • along the Ext. iliac vein
  • and the medial side of
  • pelvic wall
  • Obturator N.
  • Along the common iliac A.
  • up to the aortic bifurcation

.
.
12
Extracorporeal urinary diversion
  • through incision for speciemen
  • removal
  • GIA stappler
  • ileal conduit or ileal neobladder
  • is made in the usual manner
  • 4th port expanded for stoma

    108.0)

  • Neobladder group 698.8 ( 104.3)
  • Mean estimated blood loss (SD) 709.5 (
    496.1)
  • Days to ambulation 4.1 days (3-5)
  • Days to oral intake 4.5 days (2-6)
  • Post-op hospital stay 12.8 days (7-26)
  • Urethrectomy 17 cases

Perioperative complications
Early complications (lt30 days) Patients (n)
Ileus Intestinal obstruction Stoma site stricture Urine leakage Wx. Problem 6 1 (small intestine segmentectomy) 2 1 (W-neobladder) 3

Urethrectomy
  • Indications carcinomatous involvement of the
    urethra,
  • typically prostatic
    urethra
  • High risk of urethral recurrence

Campbell-Walsh urology 9th ed.
  1. involvement of the prostatic urethra
  2. multifocal disease
  3. the presence of carcinoma in situ (CIS)
  4. involvement of the bladder neck
  5. upper tract TCC

Urol Clin North Am 200532199-206
19
Urethrectomy in catholic experience
  • Of total 36 patients, 17 cases of total
    urethrectomy was done
  • In 17 cases
  1. Positive margin of urethra 4 cases
  2. involvement of the bladder neck 9 cases
  3. the presence of carcinoma in situ (CIS) 1
    cases
  4. involvement of the prostatic urethra 3 cases

21
Standard PLND vs Extended PLND
  • lymphatic tissue of
  • common iliac V and
  • up to aortic bifurcation
  • More accurate staging
  • Therapeutic benefit

  • In catholic experience
  • oncological efficacy comparable to other
    reports of LRC
  • possible to replicate oncologic results of ORC

Long term (over 5 yrs) oncologic survey Large
scale survey
24
CONCLUSION The main problems to define the
role LRC
  • Technical difficulty
  • Urinary diversion method

Laparoscopic radical cystectomy is technically
feasible
.
  • Extracorporeal urinary diversion with small
    incision
  • maintains the benefits of laparoscopy
  • safe and effective method
  • providing comparable perioperative and
    functional outcomes
  • as open suregery
  1. Oncologic risk , replicating the outcome of open
    surgery ?

.
Need for technical advance for orthotopic
neobladder !!
25
  1. Oncologic risk , replicating the outcome of open
    surgery ?


Not yet !!
  • Oncological outcomes from several centers
    experiences
  • including catholic university may suggest the
    possiblity of
  • replicating oncological outcomes of ORC
  • Large number and long-term oncologic data is
    required to
  • document long term cancer control with LRC
