机器人辅助腹腔镜下根治性前列腺切除术16例报告

目的 总结机器人辅助腹腔镜下根治性前列腺切除手术效果及安全性. 方法 使用da Vinci S手术机器人系统完成机器人辅助腹腔镜下根治性前列腺切除术16例.患者年龄62～76岁,平均69岁.实验室检查t-PSA 0.2～79.2 ng/ml,前列腺体积9.8～232.9 ml,前列腺穿刺活检病理证实为前列腺腺癌15例,Gleason评分平均7(4～9)分,术前临床分期T2aN0M0 3例、T2hN0M04例、T2cN0M08例;前列腺上皮内瘤Ⅲ级1例.术后随访血清t-PSA变化及患者控尿效果. 结果 16例手术均成功,无机械故障或其他原因导致的术式改变.术前机器人准备时间64(60～90)min,手术时间236(190～390)min.患者术中出血量231(50～500)ml,术后2～3 d下床活动,10～14 d拔除留置尿管,术后平均住院时间13(6～19)d.2例术后病理切缘阳性,病理分期均为pT3bN0M0.术后1个月复查t-PSA均<0.2 ng/ml.随访6～12个月,平均9个月,t-PSA均无升高.术后3、6个月控尿有效率分别为94%(15/16)和100%(16/16),其中75%(12/16)和88 0A(14/16)完全脱离尿垫.结论 机器人辅助腹腔镜下根治性前列腺切除术创伤小,安全可靠,是泌尿外科微创手术的发展方向.

Robot-assisted laparoscopic radical prostatectomy: report of 16 eases

Objective To summarize the first 16 eases in mainland China and to discuss the cli-nical experience of robot-assisted laparoseopie radical prostateetomy(RLRP). Methods Sixteen pa-tients with localized prostate carcinoma underwent RLRP with da Vinci S surgical system (Intuitive Surgical Inc.). The age of the patients was 62-76 years, average 69 years. The preoperative t-PSA level was 0.2-79. 2. Ng/ml. The volume of prostate was 9.8-232.9 ml. Fifteen patients were with biopsy-proven prostate cancer, the average Gleason score was 7(4-9). Three were T2a. N0 M0, 4 were T2b N0 M0 and 8 were T2c N0/M0 by clinical stage. One was prostatic intraepithelial neoplasm-Ⅲ. The level of t-PSA in serum and the result of urinary continence were followed up after RLRP. Results All the operations were accomplished successfully. The mean preoperative set-up time of the da Vinci surgical system was 64(60--90)min;the mean operation time was 236(190--390)rain;the mean esti-mated blood loss was 231(50-500)m.L The patients were ambulant between the 2nd and 3rd postop-erative days. Foley catheter was sueeeasfully removed on day 10 to 14, and mean hospital stay was 13 (6-19) days. Two eases had positive surgical margins, the pathological stages were both pT3b N0 M0. The average serum t-PSA was less than 0. 1 ng/ml during a median follow-up of 9(6-12) months. By the conventional definition of urinary continence (0 to 1 pads daily), 94%(15/16) and 100% (16/16)of patients were continent at 3 and 6 months, respectively. Of the patients, 75% (12/16)and 88% (14/16)had no urinary leakage(0 pads daily). Conclusions RLRP is small incision and safe. It is the direction of minimally invasive urologic surgery.
