Chronic esophageal ulceration after endoscopic sclerotherapy.

Ulceration at the site of injection is a common sequel of endoscopic sclerotherapy. Most postsclerotherapy ulcers heal spontaneously, usually within 3 weeks. We report a patient who developed a large esophageal ulcer after sclerotherapy, which did not heal despite 2 years of aggressive medical therapy. He bled twice from the ulcer. This is the first report in which such an ulcer has been followed sequentially for 2 years and has remained unhealed.
