Polypectomy at colonoscopy has been shown to reduce the subsequent risk of colorectal cancer. With the advent of national screening programs, the number of colonoscopies performed has increased worldwide. In addition, the recent drive for quality improvement combined with advances in colonoscopic technology has resulted in increased numbers of polyps detected, resected, and sent for histopathology leading to spiraling costs associated with the procedure. Being able to diagnose small polyps in vivo (optical diagnosis) would allow for adenomas to be resected and discarded without the need to retrieve them or send them for formal histopathology.
结肠镜下息肉切除术已被证明可降低后续患结直肠癌的风险。随着国家筛查项目的出现,全球范围内进行的结肠镜检查数量有所增加。此外,近期对质量改进的推动以及结肠镜技术的进步,导致检测到、切除并送去做组织病理学检查的息肉数量增加,从而使该手术的成本不断攀升。能够在体内诊断小息肉(光学诊断)将使腺瘤得以切除并丢弃,而无需取出或送去做正式的组织病理学检查。
