A 66-year-old man with alcoholic liver cirrhosis was admitted to our hospital for endoscopic injection sclerotherapy (EIS) in December 1997. He was submitted to EIS using 1% aethoxysklerol. After two sessions of EIS, a hyperemic area with marginal irregularity was detected in the posterior wall, 33cm distal from his incisor. It was not stained by iodine, and was diagnosed as squamous cell carcinoma histologically in the biopsied specimen. Because endoscopic ultrasound sonograpy showed that the carcinoma located only in the epithelial layer, we perfoemed endoscopic mucosal resection using EEMR (endoscopic esophageal mucosal resection) -tube.
There have been 20 cases of esophageal carcinoma after EIS reported in Japan. But there was no case of esophageal carcinoma discovered by EIS.
