To evaluate the results of endoscopic canaliculodacryocystorhinostomy with double probing to resolve common canalicular obstruction.

A total of 47 patients (56 eyes) with common canalicular obstruction underwent endoscopic canaliculodacryocystorhinostomy. The double probing method was applied to 28 eyes; the remaining 28 eyes were in the control group. The success rate, degree of symptom improvement, and complication rate of the two groups were compared and analyzed.

The postoperative success rate was 96% in the group that underwent surgery with the double probing method and 86% in the control group (P=0.160). The rate of symptom improvement without tearing was 86% in the double probing method group and 61% in the control group (P=0.038). Postoperative complication rates such as granuloma formation were 7% and 29% in the study and control groups, respectively (P=0.036).

Endoscopic canaliculodacryocystorhinostomy with double probing to resolve common canalicular obstruction is proven to be effective in enhancing patient satisfaction and lowering complication rates, with no additional costs and risks.
