Objective  To observe the efficacy of endoscopic nasal dacryocystoma anastomosis combined with stent implantation in the treatment of chronic recurrent dacryocystitis.    Methods  Thirty patients (30 eyes) with chronic dacryocystitis who had relapsed after traditional endoscopic nasal dacryocystorhinostomy were hospitalized in the Department of Otolaryngology Head  and Neck Surgery department of Gansu Provincial People’s Hospital from January 2010 to January 2019. Nasal lacrimal anastomosis under endoscope, intraoperative combined stent implantation, 3 months after operation, the lacrimal duct stent was removed, the patient’s tearing symptoms were observed, the lacrimal duct was flushed to determine the lacrimal duct obstruction, and the follow-up period was 12 months.    Results  Twelve months of follow-up to 12 months, 14 eyes of 30 patients had no complaints of tearing, tearing, and lacrimal tract flushing; The ostomy fistula was unobstructed under nasal endoscope and the fistula was not significantly reduced. There was no complaint of tears in the eyes, tears overflowed, and the lacrimal duct was flushed, but the fistula opening was reduced.;Four eyes showed granulation hyperplasia next to the fistula, which blocked the fistula again. The overall effective rate was 87%.    Conclusion  Endoscopic dacryocystorhinostomy combined with stent implantation is an effective method  for the treatment of chronic recurrent dacryocystitis with good clinical result .
