Curative effects and its related factors of lacrimal duct intubation with double tube under lacrimal endoscope for treating chronic dacryocystitis

Objective To explore the clinical curative effects and its related factors of lacrimal duct intubation with double tube under lacrimal endoscope for treating chronic dacryocystitis. Methods From January 2013 to May 2014, 139 patients (152 eyes) with chronic dacryocystitis received lacrimal duct intubation with double tube under lacrimal endoscope were collected from department of ophthalmology of the fourth people’s hospital of Shenyang. Gender, age, course, extubation time and curative effect were recorded. Statistics were used to analyze the relevant factors. The final data using Mann-Whitney rank test or Spearman correlation test. Results After postoperative follow-up 6~12 months, 139 cases (152 eyes) in patients with chronic dacryocystitis cured 130 eyes (85.5%), improvement in 8 eyes (5.3%), invalid 14 eyes (9.2%), the total effective rate was 90.8%. All patients had no obvious complications. Single factor analysis showed that the curative effects in patients with different gender and different course had no statistical significance (P >0.05), while in patients with different ages, different extubation sequence and different extubation time the difference all had statistical significance. Conclusions The curative rate of lacrimal duct intubation with double tube under lacrimal endoscope for treating chronic dacryocystitis is high without obvious complication. Preoperative fully consider the impact on curative effects in patients of different ages, and after extubation regularly followed-up and strictly control the extubation order and extubation time, it can further improve the success rate.
