It is widely recognized that the ingestion of lye is a frequent cause of esophageal stenosis that necessitates lifelong bougie dilation or resection with replacement, commonly by colon.

The development of carcinoma at the site of stricture, although described as early as 1941, has not been frequently commented on. Appleqvist and Salmo estimate that some 70 cases have been reported in the past, but they extract from their 2,414 cases of esophageal cancers 63
