    Abstract:

    AIM: To investigate the feasibility of endoscopic dacryocystorhinostomy (En-DCR) with bicanalicular silicone tube intubation for treating chronic dacryocystitis secondary to nasolacrimal duct stent (NDS) incarceration. METHODS: En-DCRs were performed on 44 chronic dacryocystitis patients (46 eyes) secondary to NDS incarceration from April 2016 to October 2022. The granuloma and scar tissues were separated, and the removal of NDS incarceration was achieved during the surgery; the flap of the lacrimal sac was trimmed and anastomosed with nasal mucosal, a bicanalicular silicone tube was implanted, and lacrimal size and condition were assessed. The tube was removed 3mo after surgery. During the final follow-up of 12mo when the surgery was completed, the complications and the rates of surgical success were assessed. RESULTS: This study covered 40 patients (42 eyes). Intraoperatively, it was found that the lacrimal sac became small, and the sac wall had granulation and scar tissue attached to the incarcerated NDS in all eyes. At 12mo after surgery completed, the rates of the functional and anatomical success reached 80.95% (34/42) and 83.33% (35/42), respectively. Under the effect of intranasal ostial closure, seven eyes failed to achieve anatomical success. No serious complications (e.g., visual impairment, sinusitis, and orbital fat prolapse) was observed. CONCLUSION: With the success rate over 80% and no serious complications, En-DCR with bicanalicular silicone tube implantation is effective in treating chronic dacryocystitis secondary to NDS incarceration.
