title: Ileocecal duplication cysts: is the loss of the valve always necessary?
abstract: BACKGROUND
  Ileocecal (IC) duplication cysts are enteric duplications located at the IC junction, not clearly identified in all the published series. The reported treatment is IC resection and ileocolic anastomosis. It is well known that the loss of the IC valve has several adverse effects. This study is aimed at demonstrating that cyst removal together with the common ileal wall and following enterorrhaphy is possible, safe, and effective in preserving the IC region.
  
  
  METHODS
  Medical records of 3 patients who underwent surgery for IC duplication between 2003 and 2013 were retrospectively reviewed evaluating follow-up results.
  
  
  RESULTS
  All patients had an antenatal diagnosis of intraabdominal cystic mass. In two cases associated malformations were reported. The lesions presented at newborn age with intermittent small bowel obstruction and required removal. No patients underwent IC resection. The diagnosis of duplication cyst was confirmed by histo-pathologic examination. The postoperative course was uneventful, even in the long-term follow-up.
  
  
  CONCLUSIONS
  Our conservative approach is a simple and safe technique, effective in avoiding the loss of the IC valve in children with duplication at the IC junction.
