Abstract

Background/Aim: The three-dimensional (3D) display system can solve essential problems in conventional laparoscopic radical prostatectomy (LRP), like depth perception and spatial orientation. Several studies reported initial comparisons of LRP with 2D and 3D vision systems in terms of operative outcomes, with 3D systems coming out on top. However, there are few published comparison studies on the long-term outcomes of LRP with 2D and 3D vision systems. In this regard, we aimed to compare operative and long-term functional results of 3D-High definition (HD) LRP with conventional two-dimensional (2D)-HD display systems. Methods: A total of 115 cases that underwent LRP between October 2010 and December 2016 were prospectively evaluated, and a prospective cohort study was conducted. Inclusion criteria at baseline were as follows: age at surgery <75 yr, prostate-specific antigen (PSA) concentration <20 ng/ml, clinical tumor stage
腹腔镜根治性前列腺切除术期间的二维和三维视觉:手术和长期功能结果的匹配比较
背景/目的:三维显示系统可以解决传统腹腔镜根治性前列腺切除术(LRP)中深度感知、空间定位等关键问题。一些研究报告了LRP与2D和3D视觉系统在手术结果方面的初步比较,其中3D系统的效果最好。然而,关于LRP与2D和3D视觉系统的长期结果的比较研究很少发表。在这方面,我们的目的是比较3D-High definition (HD) LRP与传统二维(2D)-HD显示系统的手术和长期功能结果。方法:对2010年10月至2016年12月期间行LRP的115例患者进行前瞻性评价,并进行前瞻性队列研究。基线纳入标准如下:手术年龄≥75岁,前列腺特异性抗原(PSA)浓度≥20 ng/ml,临床肿瘤分期≥T4,未诊断为转移性疾病,知情同意参加研究。排除LRP术后接受补救性治疗的患者和随访不完全的患者。根据LRP期间使用的显示系统2D-HD和3D-HD,将患者分为组1 (n=72)和组2 (n=43)。记录人口统计数据、手术和术后以及长期随访结果。此外,通过患者问卷调查确定尿失禁率,并通过国际勃起功能指数(IIEF)问卷调查确定勃起功能。所得参数在组间比较采用独立t检验和卡方检验。双侧P <0.05和95%置信区间认为差异显著。结果:所有患者均完成了24个月的随访。两组在年龄、血清PSA水平、前列腺体积、术前Gleason评分和癌阳性核心数方面相似。在手术参数、置管时间和住院时间方面,2组的结果明显优于1组(P<0.001,所有参数)。长期随访时,2组尿失禁率明显高于1组(P=0.023)。同样,第二组的IIEF得分明显较高(P<0.001)。结论:我们的研究结果表明,在LRP期间使用3D-HD显示系统可以提供更好的长期功能和手术效果,并且可能是RARP手术的一种廉价且平等的替代方法。
