薬剤を注入する過程は共通している。There are roughly two types of sclerotherapy. The first is an endoscopic embolization in which a drug is injected into the esophageal varices to cause blood clots in the esophageal varices themselves and in the blood vessels that are the exclusive blood supply channels of the varices to "harden" and stop bleeding. Therapy,
The second is to first inject a drug around the esophageal varices (extravascular) to harden the esophageal wall by cell fibrosis to prevent variceal bleeding, and to make bulges to block blood flow as much as possible, then varicose veins It is an endoscopic sclerotherapy in which a drug is injected into the blood vessel to "cure" with a blood clot to stop the bleeding. From the point of view of operation, these two methods are different only in the site for injecting the drug, and have the same process for injecting the drug by puncturing a predetermined site in the esophagus with a drug injection needle.

The basic operation of endoscopic embolization therapy will be outlined from the article on page 0. As shown in FIG. 3, first, an air tube (26) having a balloon attached to the distal end is inserted into the esophagus (21), and the esophageal varices (23) formed in the esophageal wall (22) are located on the anal side or the anus side. In the stomach, the inter-anal balloon (27) is inflated and compressed to reduce the inflowing blood flow and stop the bleeding. Then, an esophageal fiberscope with a balloon (endoscope)
Insert (25) into the esophagus (21) and place the esophagus fiberscope (2
5) Insert the puncture needle (drug injection needle) (24) into the esophageal varix (23)
To the position of. Therefore, while inflating the oral balloon (28) located on the oral side of the esophageal varix (23) to stop blood flow,
After fixing the positions of the puncture needle (24) and the esophageal fiberscope (25), the puncture needle (24) is inserted into the esophageal varix (23) and a hardening agent (medicine) is injected. After that, the esophageal fiberscope is removed, a compression hemostatic balloon is inserted, and pressure bonding is performed for 30 minutes to 3 hours when the thrombosis is completed.
