AIM: To observe the efficacy of MeroGel in the treatment of dacryocystitis with small dacryocyst by transnasal endoscope dacryocystorhinostomy.

METHODS: Totally 185 cases(185 eyes)of dacryocystitis with small dacryocyst were admitted in Hankou Aier Eye Hospital from June 2014 to December 2018. MeroGel, gelatin sponge, expansive sponge and vaseline gauze were used during the dacryocystorhinostomy. Complications and recoveries were observed.

RESULTS: Less bleeding and painless in patients who used MeroGel, and the anastomotic stoma was better than other groups, the difference was statistically significant(P<0.05).

CONCLUSION: The hemostasis effect of MeroGel reduced the bleeding after DCR.At the same time, its degradability is conducive to the epithelialization of the anastomotic stoma after EN-DCR, especially after the surgery with dacryocystitis with small dacryocyst. It can inhibit the adhesion of anastomotic stoma and the peripheral granulation tissue proliferation. The success rate of dacryocystitis with small dacryocyst was improved greatly. Compared with other filling materials, there were fewer complications and more comfortable patients after using MeroGel.
