METHODS: The information of 215 cases with neonatal dacryocystitis treated by LPB with ambulatory surgery mode was analyzed retrospectively, including the cure rate, the incidence of complications and adverse reactions, as well as the reasons for not arriving at the hospital after appointment.

RESULTS: All patients accomplish LPB surgery and daytime operation management successfully. The success rate of LPB for neonatal dacryocystitis with ambulatory surgery mode was 99.6%, with few postoperative complications and adverse reactions. The reason why the children did not arrive at the hospital after appointment was mainly due to the sickness being catching a cold, pneumonia, diarrhea and other diseases, otherwise, they had to cancel or postponed the appointment.

CONCLUSION: In the course of the prevalence of the COVID-19, LPB in the treatment of neonatal dacryocystitis in ambulatory surgery mode is safe, effective and feasible. It can reduce hospitalization expenses, shorten hospitalization time, and is more conducive to the prevention and control of COVID-19, which is worthy of popularization and application.
