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 ).

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.
