[Laparoscopic pelvic lymphadenectomy in patients with localized prostate cancer]

Laparoscopic pelvic lymphadenectomy is a newly developed technique of lymph node dissection in patients with malignancy of the pelvic organs. Three patients with localized prostatic cancer underwent laparoscopic pelvic lymphadenectomy. The patients were 77 years old with stage C disease, 73 with stage B1, and 65 with stage A2. Five to ten lymph nodes were removed from each patient after laparoscopic procedures lasting 220 to 270 minutes. There were no complications during the procedures and their convalescence was uneventful. All lymph nodes were negative by pathological examination and a radical retropubic prostatectomy was done 2 weeks after the lymphadenectomy in two patients. The other patient was treated with external radiotherapy and bilateral orchiectomy. Patients with stage C cancer, a high serum level of prostate specific antigen or a high grade tumor are the best candidates for this less invasive staging procedure. The disadvantage of this procedure is long operation time and complications due to CO2 pneumoperitoneum.
