To the Editor:—  Several reviews have described methods for obtaining esophageal scrapings important for cytologic evaluation.1-3 At the time of esophagoscopy a simple and safe method yields abundant cells for cytology and often tissue for cell-block histologic examination.

Methods:—  The necessary equipment consists of a standard esophagoscope, a small rubber-tipped lumen finder, a rubber band, several glass slides, Papanicolaou fixative, and a thumb forceps. The rubber band is twisted back and forth about the tip of the lumen finder, the square edges of the band providing a cutting surface which is incapable of deep penetration (Figure). The esophagoscope is passed to a point proximal to the suspicious area. The lumen finder with the rubber band is then passed through the esophagoscope into the site in question. Several gentle toand-fro movements with the lumen finder will result in the adherence of surface scrapings to the rubber band. After withdrawal of
