Abstract

Accurate size measurement of colorectal polyps is critical for clinical decision making and patient management. This systematic review aimed to evaluate the current techniques used for colonic polyp measurement to improve the reliability of size estimations in routine practice.A comprehensive literature search was conducted across PubMed, EMBASE, and MEDLINE to identify studies relevant to size measurement techniques published between 1980 and March 2024. The primary outcome was the accuracy of polyp sizing techniques used during colonoscopy.61 studies were included with 34 focusing on unassisted and assisted endoscopic visual estimation and 27 on computer-based tools. There was significant variability in visual size estimation among endoscopists. The most accurate techniques identified were computer-based systems, such as virtual scale endoscopes (VSE) and artificial intelligence (AI)-based systems. The least accurate techniques were visual or snare-based polyp size estimation. VSE assists endoscopists by providing an adaptive scale for real-time, direct, in vivo polyp measurements, while AI systems offer size measurements independent of the endoscopist's subjective judgment.This review highlights the need for standardized, accurate, and accessible techniques to optimize sizing accuracy during endoscopic procedures. There is no consensus on a gold standard for measuring polyps during colonoscopy. While biopsy forceps, snare, and graduated devices can improve the accuracy of visual size estimation, their clinical implementation is limited by practical, time, and cost challenges. Computer-based techniques will likely offer improved accuracy of polyp sizing in the near future.

内镜下结肠息肉大小测量:技术的系统回顾。
准确测量结直肠息肉的大小对临床决策和患者管理至关重要。本系统综述旨在评估目前用于结肠息肉测量的技术,以提高常规实践中结肠息肉大小估计的可靠性。对PubMed、EMBASE和MEDLINE进行了全面的文献检索,以确定1980年至2024年3月期间发表的与尺寸测量技术相关的研究。主要结果是结肠镜检查中使用的息肉大小技术的准确性。纳入61项研究,其中34项侧重于无辅助和辅助内窥镜视觉评估,27项侧重于基于计算机的工具。内窥镜医师在视觉尺寸估计上存在显著差异。确定的最准确的技术是基于计算机的系统,例如虚拟尺度内窥镜(VSE)和基于人工智能(AI)的系统。最不准确的技术是视觉或基于陷阱的息肉大小估计。VSE通过为实时、直接、活体息肉测量提供自适应刻度来帮助内窥镜医生,而AI系统则提供独立于内窥镜医生主观判断的尺寸测量。本综述强调需要标准化、准确和可访问的技术来优化内窥镜手术中大小的准确性。在结肠镜检查中测量息肉的金标准尚无共识。虽然活检钳、圈套和分级装置可以提高视觉尺寸估计的准确性,但它们的临床应用受到实用性、时间和成本的限制。在不久的将来,基于计算机的技术可能会提高息肉大小的准确性。
