Abstract
THE INCIDENCE of burns of the esophagus due to the accidental or deliberate ingestion of corrosive substances is declining, but it is still a serious and distressing problem. The modern management of acute chemical burns to the esophagus has reduced the incidence of stricture, but it still occurs, necessitating complicated surgical procedures for its correction. We have produced lye burns of the esophagus in dogs and prevented the subsequent development of stricture by early skin grafting. Its use in an initial clinical case ended fatally because of technical errors. Experimental Lye Burns Methods. —Experimental stricture was produced in a series of dogs using 5% sodium hydroxide. An ordinary Foley catheter was modified by plugging the distal end ( C ), and attaching a second balloon 12 cm proximal to the Foley balloon (Fig 1). Holes were made in the body of the catheter, and under endotracheal general anesthesia the catheter was introduced
