Method for inserting endoscopic device into hollow organ using guide wire

摘要

In a disclosed method for inserting an endoscopic device, in a state in which a guide wire is inserted through an opening of a hollow organ of a subject, the guide wire is indwelt in the hollow organ. Next, a flexible endoscope is made to approach the opening of the hollow organ. Next, inside of the body of the subject, an endoscopic device that projects from the tip of a channel of the endoscope slidably engages with the guide wire. Next, the endoscopic device is inserted into the hollow organ through the opening, along the guide wire. The guide wire that is indwelt once is subsequently used as a guide for second and subsequent insertions of endoscopic devices.

1. A method for inserting an endoscopic device into a hollow organ, comprising:
a first step of indwelling, in a region in which a first hollow organ communicates with a second hollow organ via an opening in a body of a subject, a guide wire in the first hollow organ such that the guide wire is kept to be inserted through the opening; a second step of making a flexible endoscope approach the opening in the first hollow organ, the flexile endoscope being provided with a channel; a third step of slidably engaging an endoscopic device that projects from a tip of the channel of the endoscope with the guide wire inside the body of the subject; and a fourth step of inserting, along the guide wire, the endoscopic device into the first hollow organ through the opening.
