172 Alimentary tract duplications are rare anomalies found in one out of every 4500 autopsies1. Usually, the duplication has variable symptoms, location and size. The origin of such anomaly remains unknown2. Fitz recognized the condition as intestinal duplication in 1884. Ladd in 1930 described the three essential features of esophageal duplication as follows: internal lining similar to alimentary tract; having smooth muscle layer; and proximity to a part of the alimentary tract3. The duplications are usually located on the mesenteric border1.
