title: A case series of symptomatic intraluminal duodenal duplication cysts: presentation, endoscopic therapy, and long-term outcome (with video).
abstract: BACKGROUND
  Duodenal duplication cysts are rare congenital anomalies. Symptomatic cases have classically been treated by surgical resection, which can be complex because of the close proximity of the cysts to the papilla.
  
  
  OBJECTIVE
  To describe a series of 8 patients with symptomatic duodenal duplication cysts who were treated endoscopically, with a special focus on the long-term outcome.
  
  
  METHODS
  Retrospective case series.
  
  
  METHODS
  Three tertiary-care European academic hospitals.
  
  
  METHODS
  Eight patients, age 8 to 72 years, were treated endoscopically for symptomatic intraluminal duodenal duplication cysts between 1981 and 2006. Seven patients presented with acute pancreatitis, and one patient presented with jaundice.
  
  
  METHODS
  Endoscopic incision and marsupialization of the cysts was performed by using a variety of endoscopic tools (needle-knife and regular sphincterotomes, cystotomes, and polypectomy snares).
  
  
  METHODS
  Technical success of endoscopic intervention and long-term clinical recurrence of symptoms.
  
  
  RESULTS
  No major complications occurred. All patients remained asymptomatic at a median follow-up of 7.3 years.
  
  
  CONCLUSIONS
  Retrospective study; the small number of patients.
  
  
  CONCLUSIONS
  The endoscopic treatment of symptomatic intraluminal duodenal duplication cysts is a safe and effective technique, with excellent long-term results. It represents a minimally invasive alternative to surgical resection and might be considered the preferred therapeutic modality for these cases.
