Oesophagoscopy will establish a definite preoperative diagnosis of a radiologically suspected malignancy by guided biopsy and/or brush cytology. The rigid instruments should only be used for photodocumentation since the hazards are considerably greater compared with the fibre-endoscopes. In obstructing lesions of the lower third of the oesophagus where a primary gastric cancer is suspected a passage of the instrument into the stomach should be attempted since a positive biopsy is easier obtained after a U-turn manoeuvre.
食管镜检查可通过引导活检和/或刷检细胞学对放射学怀疑的恶性肿瘤进行明确的术前诊断。硬质器械仅应用于拍照记录,因为与纤维内镜相比,其风险要大得多。在怀疑为原发性胃癌的食管下三分之一梗阻性病变中,应尝试将器械插入胃内,因为在进行翻转操作后更容易获得阳性活检结果。
