细针型共聚焦激光显微内镜及其深度学习模型在胃上皮下病变诊断中的应用研究
发布时间:2021-06-11 01:48
研究背景和目的胃上皮下病变是临床上内镜检查的常见疾病,由于其缺乏特异性的临床表现和实验室检查指标,常在患者进行胃镜检查时偶然发现。胃上皮下病变的病理组织学类型多样,一般可分为非肿瘤性病变和肿瘤性病变(包括良性肿瘤性病变、潜在恶性肿瘤性病变和恶性肿瘤性病变),其生物学行为表现差异极大。胃上皮下病变的胃镜下表现极其相似,通常表现为被覆正常组织粘膜的半球形或球形的隆起型病变。因而,仅仅依靠普通白光内镜检查难以对胃上皮下病变进行准确的诊断。超声内镜(endoscopic ultrasound,EUS)检查是临床上评估胃上皮下病变的最常用手段之一。通过白光内镜和超声的有效结合,EUS可以充分评估胃上皮下病变的病变部位、大小、起源层次、形状、边缘以及回声强度等情况。但EUS检查后无法获取病变的病理组织学标本,其对胃上皮下病变的诊断准确率仅能达到45.5%~66.3%。近年来,多种先进内镜技术如EUS引导下细针抽吸活检术(EUS-guided fine-needle aspiration,EUS-FNA)和EUS 引导下Trucut穿刺活检术(EUS-guided trucut biopsy,EUS...
