Endoscopic biopsy is an important tool for histological diagnosis of lesions residing in gastrointestinal tracts. However, it is less useful in submucosal lesions due to the existence of normal overlying mucosa. We developed a new and safe technique for the diagnosis of submucosal tumor using Stiegmann-Goff endoscopic ligator. After removing surface mucosa to expose submucosal tissue by this method, conventional secured histological diagnosis could be performed. To determine definitive histological diagnosis, this technique is useful as well as Endoscopic Ultrasound (EUS) with fine needle aspiration biopsy and other modalities.
内镜活检是胃肠道病变组织学诊断的重要工具。然而，由于存在正常的覆盖黏膜，它在黏膜下病变的诊断中作用较小。我们开发了一种使用施蒂格曼-戈夫内镜结扎器诊断黏膜下肿瘤的新的安全技术。通过这种方法去除表面黏膜以暴露黏膜下组织后，即可进行常规的可靠组织学诊断。为了确定明确的组织学诊断，该技术与内镜超声（EUS）联合细针穿刺活检及其他方法一样有用。
