We reviewed the radiographic examinations of the esophagus and medical records in 117 patients (55 women and 62 men; mean age, 52 years) in which a marshmallow bolus was also given. A one-third to one-half piece of a standard marshmallow was used with a mean size of 23 mm (+/- 4.5 mm SD) measured in vivo. In 62 patients with no intrinsic structural narrowing of the esophagus, impaction occurred in only seven (11%). Four of these patients had an esophageal motility disorder, and three had a previous Nissen fundoplication. The remaining 55 patients had lower esophageal mucosal rings (47) or peptic strictures (8). Marshmallow impaction was seen in 27 of 47 rings (57%) and was inversely related to ring size, and in six of eight strictures (75%). Also, impaction was related to the ratio of bolus size to ring caliber, and invariably occurred when this ratio was greater than 1.5. Dysphagia was the presenting complaint in 76 (65%) patients, but was found equally in those without intrinsic narrowing and in those with ring or stricture. However, dysphagia was reproduced by the marshmallow bolus only in patients with esophageal narrowing or abnormal motility.
