Conventional gastroscopes have a diameter of 8.8-12 mm; ultrathin endoscopes have an outer diameter of 5.3-5.9 mm. We share our experience with 50 patients who underwent transnasal esophagogastroduodenoscopy using an ultrathin endoscope. The indications included endoscopyassisted nasogastric tube placement in 25 patients, tight lesions not negotiable with conventional endoscope in 9, restricted mouth opening in 9, corrosive injury in 3, restricted cervical spine movement in 2 and altered sensorium following cerebrovascular accident in 2 patients. Transnasal esophageal intubation failed in 1 patient each with oropharyngeal malignancy and lipoma annularis coli. Wire-guided naso-jejunal tube placement was done in 2 patients and transnasal percutaneous endoscopic gastrostomy was done in 1 patient. Two patients developed self-limiting epistaxis. Ultrathin transnasal esophagogastroduodenoscope is a useful tool in endoscopy units, particularly those dealing with oncology patients. Inability to deliver endotherapy due to small diameter of the working channel is a limitation.
传统胃镜的直径为8.8 - 12毫米；超细内镜的外径为5.3 - 5.9毫米。我们分享了50例使用超细内镜进行经鼻食管胃十二指肠镜检查患者的经验。适应证包括25例内镜辅助鼻胃管置入、9例常规内镜无法通过的狭窄病变、9例张口受限、3例腐蚀性损伤、2例颈椎活动受限以及2例脑血管意外后意识改变的患者。1例口咽恶性肿瘤和1例结肠环状脂肪瘤患者经鼻食管插管失败。2例患者进行了导丝引导下鼻空肠管置入，1例患者进行了经鼻经皮内镜下胃造口术。2例患者出现了自限性鼻出血。超细经鼻食管胃十二指肠镜是内镜科室的一种有用工具，尤其是在处理肿瘤患者时。工作通道直径小导致无法进行内镜治疗是一个局限性。
