Observation of three children dying with uncontrollable vomiting, suggestive clinically of incomplete obstruction, has shown the importance of the only necropsy finding which seemed to be pertinent, namely, the presence of partial obstruction due to transduodenal bands. Certain blood chemical findings have supported this supposition.
The duodenum has been estimated to be the seat of 30 per cent, of all cases of congenital obstructions from the pylorus to the anus.1 At necropsy, it is not at all rare to find congenital bands attached to various portions of the intestines which probably played no part in the disease causing death. The lower intestine is more commonly the seat of peritoneal bands. Harvey2 found twenty instances in 105 necropsies on infants.
TYPES OF DUODENAL OBSTRUCTION
Congenital obstruction of the duodenum occurs as a development malformation, usually with a complete atresia or absence of one portion, and rarely as a stenosis.
