3D腹腔镜在胆囊结石及胆总管结石手术中的应用进展

Application Progress of 3D Laparoscopy in Cholecystolithiasis and Choledocholithiasis Surgery

摘要: 胆石症是胆道系统最常见的良性疾病，腹腔镜手术已成为其外科治疗的首选方案。传统二维腹腔镜因缺乏立体深度感知，在Calot三角解剖、胆管缝合等精细操作中存在视觉局限，尤其在高危解剖场景下增加了术中误判风险。三维腹腔镜技术的成熟为胆道微创外科提供了新的技术手段。本文系统梳理了3D腹腔镜在腹腔镜胆囊切除术及腹腔镜胆总管探查术中的技术原理、临床应用证据与研究进展，并通过量化汇总多项Meta分析与随机对照试验的核心数据，对比其与2D腹腔镜的临床疗效与安全性。现有证据表明，3D腹腔镜可有效还原术区立体景深，提升解剖辨识度与精细操作精度，在困难胆囊切除及胆总管探查一期缝合等复杂手术场景中优势更为突出，但对低难度常规手术的临床增益有限。此外，3D技术仍面临设备成本高、部分术者视觉不适等现实制约。未来，随着4K超高清成像、荧光导航、增强现实及人工智能辅助系统的深度融合，3D腹腔镜有望进一步推动胆道微创外科向精准化、智能化方向发展。

Abstract: Cholelithiasis is the most common benign disease of the biliary system, and laparoscopic surgery has become the first choice for its surgical treatment. Conventional two-dimensional laparoscopy lacks stereoscopic depth perception, which creates visual limitations in fine operations such as Calot’s triangle dissection and bile duct suturing, and increases the risk of intraoperative misjudgment especially in high-risk anatomical scenarios. The maturation of three-dimensional laparoscopic technology has provided new technical means for biliary minimally invasive surgery. This paper systematically summarizes the technical principles, clinical application evidence and research progress of 3D laparoscopy in laparoscopic cholecystectomy and laparoscopic common bile duct exploration, and quantitatively aggregates core data from multiple meta-analyses and randomized controlled trials to compare its clinical efficacy and safety with 2D laparoscopy. Current evidence shows that 3D laparoscopy can effectively restore the stereoscopic depth of the surgical field, improve anatomical recognition and fine operation accuracy, and has more prominent advantages in complex surgical scenarios such as difficult cholecystectomy and common bile duct exploration with primary suture, but its clinical benefit for low-difficulty routine surgeries is limited. In addition, 3D technology still faces practical constraints such as high equipment cost and visual discomfort in some operators. In the future, with the deep integration of 4K ultra-high-definition imaging, fluorescence navigation, augmented reality and artificial intelligence-assisted systems, 3D laparoscopy is expected to further promote biliary minimally invasive surgery toward precision and intelligence.
