Abstract：
UNASSIGNED: For early gastrointestinal lesions, size is an important factor in the selection of treatment. Virtual scale endoscope (VSE) is a newly developed endoscope that can measure size more accurately than visual measurement. This study aimed to investigate whether VSE measurement is accurate for early gastrointestinal lesions of various sizes and morphologies.
UNASSIGNED: This study prospectively enrolled patients with early gastrointestinal lesions ≤20 mm in size visually. Lesion sizes were measured in the gastrointestinal tract visually, on endoscopic resection specimens with VSE, and finally on endoscopic resection specimens using a ruler. The primary endpoint was the normalized difference (ND) of VSE measurement. The secondary endpoints were the ND of visual measurement and the variation between NDs of VSE and visual measurements. ND was calculated as (100 × [measured size - true size] / true size) (%). True size was defined as size measured using a ruler.
UNASSIGNED: This study included 60 lesions from April 2022 to December 2022, with 20 each in the esophagus, stomach, and colon. The lesion size was 14.0 ± 6.3 mm (mean ± standard deviation). Morphologies were protruded, slightly elevated, and flat or slightly depressed type in 8, 24, and 28 lesions, respectively. The primary endpoint was 0.3 ± 8.8%. In the secondary endpoints, the ND of visual measurement was -1.7 ± 29.3%, and the variability was significantly smaller in the ND of VSE measurement than in that of visual measurement (p < 0.001, F-test).

摘要：
■对于早期胃肠道病变，大小是选择治疗方法的重要因素。虚拟尺度内窥镜（VSE）是一种新开发的内窥镜，可以比视觉测量更准确地测量尺寸。这项研究旨在研究VSE测量是否准确用于各种大小和形态的早期胃肠道病变。
■本研究前瞻性招募了目测尺寸≤20mm的早期胃肠道病变患者。在胃肠道视觉上测量病变大小，用VSE内镜切除标本，最后用尺子在内窥镜切除标本上。主要终点是VSE测量的归一化差异(ND)。次要终点是视觉测量的ND以及VSE的ND与视觉测量的ND之间的变化。ND计算为(100X[测量尺寸-真实尺寸]/真实尺寸)(%)。真实尺寸定义为使用标尺测量的尺寸。
■这项研究包括2022年4月至2022年12月的60个病变，每个病变20个位于食道，胃,和结肠。病变大小为14.0±6.3mm(平均值±标准偏差)。形态突出，稍微升高,8、24和28个病灶的平坦或轻度凹陷型，分别。主要终点为0.3±8.8%。在次要端点中，视觉测量的ND为-1.7±29.3%，VSE测量的ND变异性明显小于视觉测量（p<0.001，F检验）。
■VSE测量对于各种大小和形态的早期胃肠道病变是准确的。
