We describe our experience of the diagnosis and removal of foreign bodies from the pharynx and oesophagus using transnasal flexible laryngo-oesophagoscopy (TNFLO) under local analgesic. The advantages of this novel instrumentation and technique are discussed.
Patients were examined with a Pentax 80K Series Digital Video Endoscope after local analgesia. The instrument was passed transnasally examining the oro- and hypopharynx, and then passed into the oesophagus. The presence, type and site of a foreign body could then be established. If a foreign body was detected, such as fish bone, it was extracted using flexible grabbing forceps passed down the instrument channel and delivered through the nasal or oral cavity. The object was then inspected to ensure removal in its entirety.
Five cases have been successfully managed using TNFLO.
TNFLO represents an improvement in the diagnosis and subsequent treatment of a selected group of foreign bodies as compared with established methodologies.
我们描述了在局部麻醉下使用经鼻柔性喉-食管镜检查（TNFLO）诊断并取出咽和食管异物的经验。讨论了这种新型器械和技术的优点。
患者在局部麻醉后使用宾得80K系列数字视频内窥镜进行检查。该器械经鼻插入，检查口咽和下咽，然后进入食管。由此可以确定异物的存在、类型和位置。如果检测到异物，如鱼刺，则使用通过器械通道插入的柔性抓取钳将其取出，并通过鼻腔或口腔取出。然后检查取出的物体，以确保全部取出。
使用TNFLO已成功处理了5例病例。
与既定方法相比，TNFLO在特定一组异物的诊断和后续治疗方面有所改进。
