Four cases of duodenal obstruction in the neonatal period caused by an annular constricting pancreatic ring are reported. These cases and the five others previously reported by different authors have been reviewed. Criteria were not found in this group of cases by which a definite preoperative diagnosis could be made. The etiology, embryology and treatment of this condition in infants have been discussed.
