Duodenal duplication cyst in an adult: first simultaneous laparoscopic and endoscopic surgery.

Duodenal duplication cysts are rare congenital anomalies. The symptoms may appear during the neonatal period or later in life, depending on the degree of gastrointestinal outlet obstruction. Classically, symptomatic cases have been treated by surgical resection or endoscopic marsupialization of the cyst. In this paper, we describe a new method of total laparoscopic resection and defect closure after precise localization of the lesion by simultaneous gastrointestinal endoscopy in a 24-year-old woman.
