Three faces of midgut duplication.

This is an analysis of three unusual cases of gastrointestinal duplications seen over a two year period. They were all males aged eight and 48 hours, and 4 1/2 years. Two had cystic duplications; in one of them it was associated with a partially fixed cecum resulting in a volvulus, while in the second the duplication occurred in association with duodenal atresia and jejunal deletion. The third patient had a tubular malformation involving distal jejunum, whole of the ileum, and right side of the colon as far as its transverse level. It was also associated with duodenal stenosis and rectal atresia. Two cystic duplications had muscular coats separate from the normal bowel permitting complete excision. Clinical presentation and pathological anatomy are briefly considered and aspects of management are discussed.
