Congenital stenosis of the duodenum is an uncommon condition, almost always fatal in early life. The reported cases, collected in several careful reviews, have all been in infants dying under 6 months. No new review will beattempted here, except briefly to summarize the conditions described. Louise Cordes1 found fifty-seven cases reported to 1901 — forty-eight of complete atresia fatal in less than nine days, and nine cases of stenosis without complete blocking, the longest duration of life in which was 6 months.
The literature later has been reviewed by Meusberger2 and Weber,3 who found that to 1910 there had been reported between sixty and seventy cases of congenital duodenal stenosis, this number representing from one fourth to one third of the total number of cases involving all parts of the small intestine — about 200. Since 1910, several additional cases have been reported by Roe and Shaw,
