Rectal Duplication Cyst Mimicking Rectal Prolapse

Abstract

Gastrointestinal tract duplications are rare congenital malformations that are benign, presenting usually in childhood. Most common sites include the distal ileum and oesophagus. Rectal presentation is quite uncommon and is usually cystic. This is a case of a three year old boy who came with rectal prolapse. On further examination and imaging investigations a presacral cyst was located and a diagnosis of rectal duplication was made. The cyst was completely excised by a posterior sagittal approach.
