Abstract
- Anal canal duplications occurring in a pair of 4 month-old healthy female twins are presented. The openings were located in the posterior midline of the anus since birth without a history of perianal abscess or swelling. Excision of the duplicated anal canals was performed using posterior sagittal approach. Although the anal canal duplication occurs predominantly in female, to our knowledge, this is the first case of anal duplication in a monozygotic female twins reported.
