胃黏膜及食管黏膜内镜活检标本,可供形成病理诊断的形态信息量很少。同时制片也较困难,特别容易发生组织丢失或混入其它别的组织造成污染。有些组织很碎小,在包埋时很难包埋在一个平面上。另外,胃黏膜及食管黏膜内镜活检均属治疗前活检,HE切片制作好坏与否,直接影响病理报告的准确性和及时性,涉及到治疗方案。因此,胃黏膜及食管黏膜内镜活检的取材、固定、脱水、透明、浸蜡、包埋、染色和封固等每个环节的工作都要重视。
Gastric mucosa and esophageal mucosa endoscopic biopsy specimens available for the formation of pathological diagnosis of morphological information is small. At the same time the filming is also more difficult, especially prone to tissue loss or contamination with other organizations. Some organizations are very small, very difficult to embed in a plane buried. In addition, gastric mucosa and endoscopic biopsy of esophageal mucosa are pre-treatment biopsy, HE section production is good or bad, directly affect the accuracy and timeliness of pathological reports, related to the treatment program. Therefore, gastric mucosa and esophageal mucosal endoscopic biopsy drawn, fixed, dehydrated, transparent, waxing, embedding, dyeing and sealing and other aspects of work should pay attention.
