title: Rectal duplication cyst in an adult: the laparoscopic approach.
abstract: BACKGROUND
  Rectal duplication cyst (RDC) is a rare congenital anomaly representing 1% to 8% of all intestinal duplications. The case presented here is the first report of the laparoscopic resection of an RDC.
  
  
  METHODS
  We report the case of a 49-year-old white woman in whom a retrorectal cystic mass measuring 5 x 5.3 x 6 cm was diagnosed. The mass was completely resected by means of laparoscopic techniques.
  
  
  RESULTS
  Pathologic findings revealed a cystic structure partially lined with squamous as well as respiratory- and gastrointestinal-type epithelium. Muscularis propria was identified in the outer portions of the wall of the specimen. No atypia or malignancy was identified. The overall findings were consistent with an RDC.
  
  
  CONCLUSIONS
  Laparoscopic resection constitutes an excellent and patient-friendly approach to the management of large adult cystic duplication of the rectum.
