使用外套管经内镜取出尖锐异物。

S Afr Med J. 1981 Nov 7;60(19):743-4.

We describe a method for the endoscopic removal of sharp foreign objects from the stomach using a plastic oversleeve. This sleeve allows repeated passage of the endoscope without discomfort and minimizes the risk of the foreign body causing damage to the mucosa or of its being dislodged from the grasping forceps as it is withdrawn.

我们描述了一种使用塑料保护套经内镜从胃内取出尖锐异物的方法。该保护套可使内镜反复通过而不会引起不适，并将异物对黏膜造成损伤的风险以及在取出过程中异物从抓取钳上脱落的风险降至最低。
