The antireflux spur-valvewas originally designed for the Roux-Y cholenterostomy. It is made by plication of the two upper limbs of the "Y" after the removal of the seromusculature from the biliary limb, so that the conjoined wall-in-between will he compassed deviating to the biliary, side to form a spur value. It could successfully stop the reflux due to normal peristalsis or intestinal distension. This value was primarily used in choledochal cyst and biliary atresia for more than 100 cases, and also applielied to many other operations for perventing reflux, including: gastroesophageal refluk-Nissen fundoplication, colon replacement of esophagus, side to side shert-circuit of intestinal obstruction, and Kock scontinent ileoslomny. The detailed procedures were described.
