Effect of different absorbable anastomotic stoma packing materials on endonasal endoscopic dacryocystorhinostomy

Abstract

AIM:To compare the effect of self-crosslinking sodium hyaluronic gel, Nasopore, and gelatin sponge in endonasal endoscopic dacryocystorhinostomy(En-DCR).METHODS:Totally 72 patients(90 eyes)of chronic dacryocystitis admitted to our hospital from June 2019 to June 2020, and randomly divide them into three groups. Self-crosslinking sodium hyaluronic gel(group A), Nasopore(group B), and gelfoam(group C)were used during the En-DCR. Comfort level, bleeding, complication and epiphora, lacrimal situation were observed 2wk, 1, 2, 3, 6mo after surgery. Comparison of cure rate and effective rate.RESULTS: The patients were followed up for 6mo after operation. The cure rate of lacrimal system reconstruction was 97% in group A, 89% in group B and 94% in group C. There was no meaningful statistical difference among the three groups(P>0.05). The effective rate of lacrimal system reconstruction was 91% in group A, 56% in group B and 87% in group C(P0.0167). Postoperative comfort level was better and bleeding was more severe in the group of A than in group B(P<0.0167). In terms of complications, there was less scar proliferation in group A than in group B(P<0.0167), the rate of synechiae in groups A and B was higher than in group C(P<0.0167).CONCLUSION:Intraoperative application of self-crosslinking sodium hyaluronic gel to packing the anastomotic stoma makes the procedure simple and can effectively inhibit scar proliferation and conducive to the epithelialization of the anastomotic stoma, improve the cure rate of En-DCR. In addition, with more comfort. It is a simple, safe, comfortable and efficient absorbable anastomotic stoma packing material.
