“超级面纱法”腹膜外单孔机器人前列腺癌根治术的手术技巧体会与临床应用分析

目的:描述超级面纱法腹膜外单孔机器人前列腺癌根治术(super-veil extraperitoneal single-port robotic assisted radical prostatectomy, sesRARP)的手术步骤,总结短期随访结果,探讨其最佳应用场景。方法:回顾性分析2018年12月—2021年6月行sesRARP的41例器官局限性前列腺癌患者的临床资料。年龄52～79岁,平均(63.9±4.3)岁;前列腺特异性抗原(PSA)中位数8.70(6.35,11.84) ng/mL,中位前列腺体积32.90(28.98,33.85) mL,术前排尿功能正常,规律行性生活。术中取耻骨上5 cm横切口。性神经保留采用超级面纱法,将双侧血管神经束及腹侧的背深静脉丛、逼尿肌裙与耻骨膀胱韧带紧贴前列腺包膜完整分离。记录围术期并发症、出院前疼痛评分、住院天数、PSA随访指标、尿控恢复时间、性功能恢复时间等。结果:平均手术时间(93.3±28.29) min。术中出血量72.7(50～150) mL,未输血。切缘阳性率为14.6%(6/41)。术后住院天数为3(1.0,3....

Super-veil extraperitoneal single-port robotic radical prostatectomy: surgical technique and clinical application

Objective: To demonstrate the surgical steps of super-veil extraperitoneal single-port robotic assisted radical prostatectomy(sesRARP), review its short-term functional outcomes, and discuss the optimal application scenario. Methods: Forty-one organ-confined prostate cancer patients who had undergone sesRARP were retrospectively included from December 2018 to June 2021. The patients aged 52 to 79 years(mean±SD, 63.9±4.3) with a baseline median prostate specific antigen(PSA) of 8.70(6.35, 11.84) ng/mL and a median prostate volume of 32.90(28.98, 33.85) mL. All patients had normal micturition and were sexually active. A 5 cm transverse incision was adopted above the pubis symphysis. Super-veil nerve-sparing technique was adopted, in which bilateral neurovascular bundles and ventral anatomical structures surrounding the prostate, namely the deep venous complex, detrusor apron and pubovesical ligaments were preserved as an entity. Perioperative complications, pain score on discharge, length of stay, postoperative PSA, and continence and potency recovery were documented. Results: Mean operative time was(93.3±28.29) min. Estimated blood loss was 72.7 mL(range, 50-150 mL). No patient required blood transfusion. Positive surgical margin was 14.6%(6/41). Postoperative length of stay was 3 days(1.0, 3.0). Pain score on discharge was 0(0, 1.75). Foley catheter was removed on postoperative day 7. No complications graded Clavien Ⅲ or above were documented. Median follow-up time was 13 months(range, 3-31 months). Twelve-month biochemical recurrence-free survival was 97.2%(35/36). Instant continence recovery was 24.4%(10/41), and 1-, 3-, 6-, and 12-month recovery were 56.1%(23/41), 70.7%(29/41), 84.6%(33/39) and 94.4%(34/36), respectively. Conclusion: Super-veil extraperitoneal single-port robotic-assisted radical prostatectomy has potential merits of less trauma, more rapid recovery, lower comorbidities, with faster short-term continence and potency recovery. It is best indicated for younger patients with localized disease and higher demand of postoperative quality of life, therefore caution must be paid on patient selection and preoperative clinical and radiological evaluations.
