摘要 目的探讨内镜下醋酸联合靛胭脂染色在胃黏膜肠上皮化生随访监测中的价值。方法纳入在该院内镜中心行随访的胃黏膜肠上皮化生患者共52例,普通胃镜下观察胃黏膜形态后行醋酸联合靛胭脂染色,分别在染色后黏膜着色不良区、周围染色正常区、普通胃镜下可疑病灶以及周围正常区各活检2块,行组织病理学检查。结果染色后52例均出现局部黏膜着色不良,在黏膜着色不良区活检的104份组织标本,其中90份标本提示有肠上皮化生,14份标本提示慢性炎症;周围染色正常区活检的104份组织标本中,4份标本提示有肠上皮化生,100份标本提示慢性炎症。普通胃镜下可疑病灶活检的104份组织标本,其中64份标本提示有肠上皮化生,40份标本提示慢性炎症;周围正常区活检的104份组织标本中,6份标本提示有肠上皮化生,98份标本提示慢性炎。染色胃镜诊断肠上皮化生的敏感性为88.5%(46/52)、特异性为50%(3/6)、阳性预测值为86.5%(90/104)及阴性预测值为96.2%(100/104);而普通胃镜分别为:69.2%(36/52)、18.8%(3/16)、61.5%(64/104)及94.2%(98/104)。染色胃镜诊断肠上皮化生的敏感性和阳性预测值均较普通胃镜高,差异有显著性(分别为P=0.016和P<0.001)。结论内镜下醋酸联合靛胭脂染色有助于提高肠上皮化生的靶向活检阳性率。
