Efficacy and safety of single canalicular intubation versus bicanalicular small annular intubation in treatment of canalicular laceration

Objective To evaluate the effectiveness and complications by using single canalicular intu-bation versus bicanalicular small annular intubation in treatment of canalicular laceration. Methods A total of 66 patients with inferior lacrimal canalicular rupture who received surgical treatment by Department of Ophthalmology in Qinhuangdao Haigang Hospital were consecuticvely recruited between Janu-ary 2009 and February 2016. They were randomly allocated to Group A or Group B. The silicone tube was placed only in the broken canalicular in Group A, and was placed annularly in both the two canaliculars in Group B. Between the two groups, Mann-Whitney Rank sum test was used to comparing the operative effect, and Chi-square test was used to comparing the occurence of complications. Results The cure rate was 39.39% in Group A and 69.69% in Group B; the improvement rate was 33.33% in Group A and 21.21% in Group B. Group B had better effect and less complications (2 cases) than Group A (12 cases), the difference between the two groups were significantly. Conclusions Compared with single canalicular intubation, bicanalicular small annular intubation has better operative effect and less complication occurs, it's worthy to be popularized.
