Clinical analysis of extraperitoneal laparoscopic radical prostatectomy by different surgical approaches

ObjectiveTo investigate the clinical analysis of extraperitoneal laparoscopic radical prostatectomy on local prostate cancer by different surgical approaches.

MethodsThe clinical data of 87 patients with local prostate cancer undergoing extraperitoneal laparoscopic radical prostatectomy were retrospectively analyzed.Among them, 28 cases underwent three-port ELRP and 59 cases underwent four-port ELRP.The clinical factors as ages, tPSA, prostate volume, clinical stage, hypertension, operative time, estimated blood loss, pathological scores, positive surgical margin rates, biochemical recurrence and drainage tube keeping days.

ResultsAll the patients underwent successful surgery without turn to open surgery.During the three-port group and four-port group, operative time were (90.56±17.87) min and(118.66±22.45) min, the estimated blood loss were(121.45±45.76)mL and (189.87±75.43) mL, prostate volume were (36.75±12.26) mL and (67.47±22.65) mL respectively, with significant statistical difference(P < 0.05).Positive surgical margin were 2 cases and 4 cases, of which underwent the endocrine therapy, with no statistical difference(P>0.05).These was no statistical difference in the other factors(P>0.05).Follow-up 3 to 17 months after surgery, biochemical recurrence in 6 cases, to endocrine control satisfaction.

ConclusionsCompared with the four-port ELRP, the three-port ELRP not only has not increased complicaiton, but also is more minimally invasive.It is worthy of clinical application for small and localized prostate cancer.
