Intestinal malrotation in Rubinstein-Taybi syndrome.

Rubinstein-Taybi syndrome (RSTS) is a multiple congenital anomaly syndrome which may include malformations of the central nervous system, heart, genitourinary tract, and other organs. However, intestinal malrotation has not been previously known to be associated with RSTS. This report documents six persons with RSTS who also had malrotation of the intestine requiring surgical repair. This suggests a possible increased frequency of malrotation in RSTS. Diagnostic studies for malrotation should be considered if recurrent vomiting, abdominal pain, and other symptoms of possible malrotation are present.
