目的

介绍一种治疗膀胱癌患者的机器人辅助膀胱癌根治术(RARC)新入路——后入路联合外侧入路,并且评价其疗效。

方法

回顾性分析行RARC的21例47~80岁膀胱癌患者的临床资料,其中采用后入路联合外侧入路患者12例,采用传统外侧入路患者9例。比较两组患者临床资料。后入路的关键步骤为在外侧入路之前首先剪开膀胱腹膜反折,松解盆腔粘连,游离膀胱后壁,显露膀胱侧韧带,并向狄氏筋膜同时逐渐显露双侧精囊和前列腺后壁,离断双侧输精管动脉。

结果

21例患者手术均顺利完成。后入路联合外侧入路组相较传统外侧入路组,输尿管造口手术时间[295.0(275.0,300.0)vs 445.0 (354.5,501.6)min,P=0.034]、回肠代膀胱手术时间[330.0(320.0,414.0)vs 490.0 (396.0,545.5)min,P=0.019]均明显缩短。两组患者术后住院时间、术后肌酐水平以及术后并发症发生率等方面,差异无统计学意义(P>0.05)。

结论

后入路联合外侧入路的手术方式具有缩短手术时间、改善术中暴露的优势,是一种安全且快速的RARC手术入路方式。

Objective

To introduce a novel robotic-assisted radical cystectomy (RARC) approach for bladder cancer patients, namely the combined posterior and lateral approach-and evaluate its efficacy.

Methods

A retrospective analysis was conducted on clinical data from 21 bladder cancer patients aged 47-80 years who underwent RARC. Among them, 12 underwent the combined posterior and lateral approach, while 9 underwent the traditional lateral approach. Clinical characteristics were compared between the two groups. The key step of the combined approach involved first incising the peritoneal reflection of the bladder prior to the lateral approach to release pelvic adhesions, mobilize the posterior bladder wall, expose the lateral bladder ligaments, and gradually expose the bilateral seminal vesicles and posterior wall of the prostate along Denonvilliers’ fascia, followed by ligation of the bilateral vas deferens arteries.

Results

All 21 patients successfully completed the surgery. Compared to the traditional lateral approach group, the combined approach group demonstrated significantly shorter ureterostomy time [295.0 (275.0, 300.0) vs 445.0 (354.5, 501.6), P=0.034] and ileal neobladder reconstruction time [330.0 (320.0, 414.0) vs 490.0 (396.0, 545.5), P=0.019]. There were no statistically significant differences between the two groups in postoperative hospital stay, postoperative creatinine levels, or postoperative complication rates (P>0.05).

Conclusion

The combined posterior and lateral approach for RARC offers advantages in reducing operative time and improving intraoperative exposure, making it a safe and efficient surgical technique for RARC.
