Laparoscopic excision of an esophageal duplication cyst.

Esophageal duplication cysts are uncommon embryologic entities that are often discovered incidentally. When identified, complete excision is the recommended treatment regardless of symptoms. We report the case of a 2-year-old boy with a distal esophageal duplication cyst discovered incidentally during laparoscopy for fundoplication. The esophageal duplication cyst was completely resected and a 360-degree fundoplication was then constructed, incorporating the cyst resection site. This is only the second report describing complete laparoscopic excision of an incidentally discovered esophageal duplication cyst in a child. This method is a safe and effective way of managing these lesions.
