Segmental colonic duplication presenting as a sigmoid volvulus.
This is a case report of a four-year-old girl who presented with severe intermittent abdominal pain. She had an infra-levator imperforate anus repaired as a newborn. Operation demonstrated duplications of the right and left colons, separated by a normal transverse colon. The left colon duplication was closed at both ends, and it contained 500 cc of intestinal secretions. The sigmoid colon and its duplication volvulized. The terminal ileum was also duplicated; one ileum joining a normal ascending colon duplication, which was patent proximally, but closed distally.
