title: [Endoscopic operation in the treatment of congenital duodenal membranous stenosis].
abstract: OBJECTIVE
  To investigate the safety and efficacy of endoscopic duodenal valvectomy in the treatment of congenital duodenal membranous stenosis.
  
  
  METHODS
  Clinical data of two children with congenital duodenal membranous stenosis undergoing endoscopic duodenal valvectomy in our institute within October 2014 were analyzed retrospectively. This procedure was performed with Microknife XL and CRE balloon catheter through porous channel in the 9 mm flexible endoscope.
  
  
  RESULTS
  The first case was a 2-year-old boy who received two endoscopic operations including duodenal diaphragm resection and duodenal dilatation because of incision retraction. The second case was a 19-month-old gril who received once endoscopic duodenal valvectomy. Duodenal obstruction of these two children was relieved after operation. Postoperative x-rays showed no perforation. They could play in the floor 6 hours after operation without any complains, drink water 12 hours, take liquid diets 2 days and half solid food 3 days after operation. During follow-up a month after operation, the body weight gained was 1.5 and 1.0 kg respectively, and the dietary components was significantly improved.
  
  
  CONCLUSIONS
  Endoscopic duodenal valvectomy is feasible and effective in the treatment of congenital duodenal membranous stenosis.
