Laparoscopic imaging has advanced significantly, with higher resolutions like 4K, and innovative light modes such as narrow band imaging and near-infrared imaging. Recently, yellow enhancement (YE) mode has emerged as a novel tool that enhances the pale-yellow colour of fat into a fluorescent yellow-green, improving contrast without the need for injected dyes. It can be toggled on and off easily during surgery. YE is still under evaluation, but early experience suggests it helps surgeons differentiate anatomical planes and key intra-abdominal structures from surrounding adipose tissue. This is particularly useful in: (1) Dissecting structures surrounded or covered by fat; and (2) operating on patients with obesity, where excess intra-abdominal fat limits visualisation and retraction. By enhancing the visibility of vascular pedicles, ureters, and nerves, YE enables more precise dissections and may reduce the risk of accidental injury. It can also assist less experienced surgeons in identifying important structures, potentially improving efficiency and surgical outcomes. As a training tool, YE may shorten the learning curve, though further study is needed. Overall, YE offers potential benefits in fat-dense surgical fields by improving visualisation, reducing complications, and enhancing patient safety.
腹腔镜成像技术有了显著进步,具备如4K这样的高分辨率,以及窄带成像和近红外成像等创新的光照模式。最近,黄色增强(YE)模式已成为一种新型工具,它能将脂肪的淡黄色增强为荧光黄绿色,无需注射染料就能提高对比度。在手术过程中可以轻松地开启和关闭该模式。YE仍在评估中,但早期经验表明,它有助于外科医生区分解剖层面以及腹内关键结构与周围脂肪组织。这在以下情况中特别有用:(1)解剖被脂肪包围或覆盖的结构;(2)为肥胖患者进行手术,因为腹内过多脂肪会限制视野和牵拉操作。通过增强血管蒂、输尿管和神经的可视性,YE能实现更精确的解剖,并可能降低意外损伤的风险。它还可以帮助经验不足的外科医生识别重要结构,有可能提高手术效率和改善手术效果。作为一种培训工具,YE可能会缩短学习曲线,不过还需要进一步研究。总体而言,YE通过改善视野、减少并发症和提高患者安全性,在脂肪密集的手术领域具有潜在益处。
