Purpose : Diagnostic sampling of pelvic lymph nodes is generally accepted as the
optimal procedure for evaluating the metastatic status of locally curable prostate
carcinoma. It is usually done by open surgery, but recent developments in laparoscopic
surgery have provided another option and are theoretically associated with less trauma
and fewer complications than those reported from conventional surgery. We now report
our experience, progression and complication of extraperitoneal laparoscopic pelvic lymph
node dissection (LPLND).
Materials and Methods : Between Dec. 1996 and Feb. 1998, 14 patients with high
serum PSA (¡Ã10 ng/§¢) or high Gleason score (¡Ã5) underwent LPLND before radical
perineal prostatectomy. The mean age of 14 patients was 64.4¡¾6.5 years. The mean of
serum PSA level was 51.4¡¾39.3 ng/§¢, and the mean Gleason score was 7.3¡¾1.6. We
used balloon dissector for the creation of extraperitoneal space, and performed LPLND
with a CO2 insufflation through extraperitonium.
Results : The average operation time was 138.2¡¾29.8 minutes and estimated
intraoperative blood loss was 80§¢. The Jackson-Pratt drain was removed 3 days
postoperatively and the mean drainage volume was 220.5¡¾105.2 §¢. The average number
of dissected nodes was 7.6¡¾4.4 (Rt.: 4.1 ¡¾2.9, Lt.. 3.5 ¡¾2.3), and LN metastasis was
noted in 4 patients(28.6%). Complications included subcutaneous emphysema(7 patients),
peritoneal laceration and obturator nerve injury. The mean dissected LN number of the
latter 9 cases was 8.6¡¾4.8 compared with 6.0¡¾3.3 of initial 5 cases, the mean operation
time (minute) of the latter 9 cases was 132.8¡¾26.6 compared with 148.0¡¾35.8 of initial 5
cases.
Conclusions : The laparoscopic approach can be performed within a resonable time limit
and allows adequate assessment of the pelvic lymph node with minimal operative
morbidity. Extraperitoneal LPLND is the minimally invasive procedure of choice for the
evaluation of patients who are at increased risk of having metastatic pelvic lymph node
involvement by prostate cancer.
