3D/2D laparoscopic radical prostatectomy：A single center experiences / 中国内镜杂志

ABSTRACT

Objective To compare the clinical effect of 2D and 3D laparoscopic radical prostectomy and summarize surgical experience of laparoscopic radical prostectomy of early prostate cancer.MethodsThe clinical data of 34 cases of prostate cancer treated in our institute from November 2015 to April 2016 were collected and analyzed retrospectively. The patients in observation group (11 cases) were treated by 3D laparoscopic radical prostectomy, while those in control group (23 cases) were given 2D laparoscopic radical prostectomy. The operation time, intraoperative bleeding volume, postoperative drainage time, quantity of drainage fluid within 24 hours postoperatively, indwelling catheter time, hospital time, positive surgical margin rate, potence rate, 30d-urinary continence rate and complications were compared between the two groups.Results All operations were successfully performed. There were no signiifcant differences in operation time, intraoperative bleeding volume, postoperative drainage time, quantity of drainage lfuid within 24 hours postoperatively, indwelling catheter time, hospital time, positive surgical margin rate, potence rate, 30d-urinary continence rate and complications between the two groups (P > 0.05). In observation group, the operation time was (153.52 ± 30.47) min and the potence rate was 50.0 %, 4 cases with uroclepsia (36.4 %), 1 case with urine leakage (9.1 %), no patient had urethral stricture or positive surgical margin, the 30d-urinary continence rate was 72.7 %. In control group, the operation time was (164.73 ± 28.65) min and the potence rate was 38.9 %, 13 cases with uroclepsia (56.5 %), 4 cases with urine leakage (17.4 %), 1 case with urethral stricture (4.3 %), 2 cases with positive surgical margin (8.7 %), 30d-urinary continence rate was 60.9 %.ConclusionLaparoscopic radical prostectomy is a safe, effective and less invasive method for treating early prostate cancer patients. Also 3D laparoscopic radical prostectomy play the similar functional results compared with 2D laparoscopic radical prostectomy, but 3D laparoscopic has the advantage in three dimensions space sense and accurate operation, it is worthy of promoting clinical application.
