RESUMO
Objective To evaluate the clinical efficacy of extraperitoneal laparoscopic radical prostatectomy(ELRP)for prostate cancer patients, and to summarize the experience of surgical treatment. Methods The clinical data of 50 prostate cancer patients who underwent ELRP by the same performer from January 2010 to June 2015 were retrospectively reviewed. Results All cases were all successfully completed ,no case was converted to open surgery. The average operation time was 238.8 min,average operative blood loss was 409.1 mL,and intraoperative or postopera?tive blood transfusion was 6(12%). The mean postoperative catheterization time was 23.7(17?38)d. The mean postoperative hospital stay was 15 (10?34)d. The postoperative recovery time of eating was 2?4 d,and the ambulation time was 1?3 d. Totally 3 cases(6%)had lymph node metasta?sis,and 7 cases(14%)had positive surgical margin. Totally 9 cases(18%)had surgery?related complication. Patients were followed up for 6 to 58 months,with an average of 12.5 months. One case(2%)had biochemical recurrence,and the tumor?free survival rate was 84%. At the end of fol?low?up,all of the patients were continent. Conclusion ELRP is safe and effective for the treatment of prostate cancer. With the development of minimally invasive techniques,the applications of RP are increasingly widespread. However,large?scale and long?term follow?up studies are still needed for high?risk prostate cancer patients.
