~MALROTATION OF THE BO\VEL CAUSING INTESTINAL OBSTRUCTION

C for ,"ast improvement in the recognition and t reatment of the complications of malrotation of the bowel is largely due to the observations of Ladd (1) and Ladd and Gross (2 )~ Congenital malrotation of the bowel, recognized for many years, is of no consequence until, because of it, specific types of intestinal obstruction occur. The obstruction is due in a measure to malrotation of the bo\\"el but primarily to congenital fibrous bands across some portion of the duodenum. These bands are the important part of the pathological anatomy of improper rotation of the intestine and colon. Only during recent years since Ladd emphasized this basic point, and demonstrated the necessity of severing these bands, have case reports in medical literature been concluded with a successful outcome following surgery rather than with the findings at postmortem examination.
