机器人辅助腹腔镜保留肾单位肾部分切除术（附6例报告）

目的：总结我院机器人辅助腹腔镜保留肾单位肾部分切除术的手术经验，探讨此术式疗效及安全性。方法：2007年12月～2008年10月，对6例肾肿瘤患者行达·芬奇机器人（Da Vinci机器人手术系统）辅助腹腔镜保留肾单位肾部分切除术，将相关资料与国外此手术初期资料及我院同组人员腹腔镜保留肾单位肾部分切除术的资料进行比较分析。结果：6例患者中，1例改行开放性保留肾单位肾部分切除术，其余5例手术均成功。手术时间（不包括术前机器人准备时间）130（110～160）min，肾动脉阻断时间40（33～50）min，术中出血量188（100380）ml。术后7天下床活动，3天拔除引流管，术后住院9（8～12）天，肾功能均在正常范围。术后病理检查提示为肾透明细胞癌5例，乳头状癌1例，无一例切缘阳性。随访4～15个月，全部患者未见局部病灶残留、局部复发、切口种植及远处转移。结论：机器人辅助腹腔镜保留肾单位肾部分切除术是一种创伤小、安全可靠、疗效确切的手术方法。随着操作熟练程度的提高，此术式优势将更加明显。

Robot-assisted Laparoscopic Partial Nephrectomy (Report of 6 Cases)

Objective:To summarize our clinical experience of robot-assisted laparoscopic partial nephrectomy (RALPN), and to discuss its efficacy and safety. Methods:Between December 2007 and October 2008, 6 patients with small exophytie renal masses underwent intraperitoneal robotic partial nephrectomy utilizing the Da Vinci sur-gical system. The perioperative data were collected, and were compared with those performed the same operation in abroad and those performed laparoseopic partial nephrectomy(LPN) with the same team in internal. Results: All the operations were accomplished successfully except the one which required conversion to open nephron-sparing surgery (NSS) due to bleeding occured after the renal artery had been clamped. The mean lesion diameter was 3.2 (2.2-3.6)cm; the mean operative time (not including preoperative set-up time of the Da Vinci surgical system) was 130 (110-160) minutes; the mean warm ischemia time were 40(33-50)minutes; the mean estimated blood loss was 188 (100-380) ml. The patients were ambulant in the 7th postoperative days, and tubes were removaled in 3 days, and mean hospital stay was 9 (8-12)days. Renal function of all patients was in the normal range. Pathology revealed renal cell carcinoma in five, papillary renal cell carcinoma in one. All resection margins were negative. Follow-up ranged from 4 to t5 months, no local residual lesions, local recurrence, incision implantation and dis-tant metastasis were found in all patients. Conclusions.. Robot-assisted laparoscopic partial nephrectomy can be safe-ly performed in selected patients, and it is a feasible approach and a minimally invasive operation for small renal tumors.
