Reversed rotation is a rare type of intestinal malrotation. Four of the 61 cases with malrotation treated at our department during the period from 1963 to June 1985, were reversed rotation. A 2-day-old baby boy was the retroarterial left-sided cecum type of reversed rotation. 12-year-old boy and 5-day-old baby boy were the right-sided cecum type. A 13-year-old boy was the prearterial right-sided cecum type. Four were admitted with bilious vomiting. Three were treated with postioning nonrotation of Ladd's Procedure and one was treated with modified Bill's procedure.
