Intestinal obstruction caused by potato bezoar in infancy: a report of three cases.

We present a report of three young infants with unusual intestinal obstruction caused by potato bezoar. They presented with vomiting, irritable crying, and abdominal distention. Barium gastrointestinal series clearly revealed intraluminal filling defect in the duodenum in two cases and ileum in one. Those bezoars in the pylorus and duodenal bulb were all successfully retrieved endoscopically. The patient's abdominal symptoms subsided after the bezoars were eliminated; no subsequent gastrointestinal events occurred in the following months. The authors believe that the occurrence of these cases suggest that feeding mashed potato to young infants (≤4 months) should be prohibited because it can result in bezoar formation.
