[Laparoscopic radical prostatectomy: initial 17 case report]

We report our early experience of laparoscopic radical prostatectomy for clinically localized prostatic cancer.

Between April and December 2000, 17 patients with clinical stage T1c to T2b prostatic cancer underwent laparoscopic radical prostatectomy. The median age was 70.9 year old, the median preoperative PSA and the median Gleason score of biopsy specimens was 7.1 ng/ml, 6, respectively. We followed the operation technique from the "Montsouris technique". Briefly, we used five trocars (two 10-mm and three 5-mm trocars) and the operation was performed transperitoneally. Pelvic lymph node dissection was performed in only one patient (case 3). Urethrovesical anastomosis was performed with 6 to 9 interrupted 3-0 absorbable sutures.

No conversion to open surgery or reoperation was required in all cases. Median operation time was 450 minutes (range 290 to 750) and median intraoperative bleeding (including urine) was 600 ml (range 100 to 3,135). Only one case (case 3) needed homologous blood transfusion. Median postoperative Foley catheterization period was 9 days (range 5 to 19). Intraoperative complications related to operation procedure were one rectal injury and three vesical injuries, which were treated by absorbable suturing laparoscopically. Major complication was one complete A-V block (case 3) who was required a transient discontinuance of the procedure. Surgical margins were negative in 13 cases. Postoperative pathological evaluation was one pT0, five pT2a, seven pT2b and four pT3a. PSA value decreased less than 0.2 ng/ml after surgery in all patients. Although six months have passed after the surgery in only 4 patients, all of them were fully continent.

Although the operation time is still longer than that of conventional open procedures, intraoperative magnified vision allows a more precise and safer dissection, especially for apical dissection. We believe that operative time will decrease with more experience. These results show that laparoscopic radical prostatectomy can be an acceptable treatment option for localized prostatic cancer.
