Esophageal endoscopic submucosal dissection (ESD) is a very common and useful endoscopic
treatment for superficial esophageal cancer [1]. The most common delayed adverse event of esophageal ESD for extensive lesions is
stenosis [2]. Local injection of triamcinolone is the most common form of stenosis prevention
[3], and the method using a needle is a rather complicated and time-consuming procedure.
A new drug-delivery balloon catheter is a device with multiple micro holes on its
surface that eject fluid from the balloon when the balloon pressure rises.
A man in his 60s underwent ESD for semiperipheral superficial esophageal cancer in
the upper thoracic esophagus ([Fig. 1]). The resected pathology was squamous cell carcinoma, and curative resection was
obtained. After resection, the mucosal defect extended to 7/8 of the circumference
([Fig. 2]), and triamcinolone 40 mg was injected into the post-treatment ulcer using the new
drug-delivery balloon catheter ([Video 1]).

catheter.Video 1
The procedure was completed in only a few minutes, and was very safe and simple. Post-procedure
observation showed that triamcinolone was injected evenly and firmly into the ulcer
([Fig. 3]).

A new drug-delivery balloon catheter allows for safe, simple, and quick triamcinolone
injection after esophageal ESD.
