Cause of failure in anastomosis of pediatric traumatic canalicular laceration

Objective To analyze the failure in anastomosis of pediatric traumatic canalicular laceration and increase the rate of success by improving the stent replacement.Methods There were 25 cases (25 eyes) of anastomosis of pediatric traumatic canalicular laceration and 10 of which were failed after surgery,To analyze the 10 cases and find out the main cause of failure.Results Among the 25 cases,there were 16 cases used the conventional method of exposed stent placement.5 cases' stents were slided in 1 week postoperatively with blocked lacrimal irrigation.5 cases' stents were slided in 1 month postoperatively and 3 cases' lacrimal irrigation were blocked.The other 9 cases used the method of potential stent placement,2 cases'stents slided because plastic pipe separated lower lacrimal canaliculi which lead to lacrimal irrigation blocked.Conclusion The main cause of failure in anastomosis of pediatric traumatic canalicular laceration was the improper placement of stent and prolapse in advance.The rate of success could be increased by using improving stent replacement.
