CONGENITAL atresia and stenosis of the intestinal tract of infants have been associated with a high mortality rate. In 1922 Davis and Poynter1 collected 392 cases. The mortality was 100 per cent for congenital occlusive lesions of the intestines between the pylorus and the rectum. It has been estimated that the condition occurs in about 1 in 20,000 infants.
In this discussion we are confining ourselves to a consideration of intrinsic congenital obstructive lesions of the duodenum. Calder in 1733 described the first case of atresia of the duodenum. During the past quarter century, with better diagnosis and surgical treatment, the mortality has been reduced. Through the surgical efforts of Ladd,2 Donovan, Miller,3 Horsley,4 Trusedale and others,5 approximately thirty successful operative recoveries have been recorded. Early surgical intervention is not always as urgent in stenosis of the duodenum and partial obstruction as in atresia.
