Objective:
To evaluate the surgical outcomes of endoscopic dacryocystorhinostomy with canalicular marsupialization (EDCR CM) in common canalicular obstruction.
Design:
Retrospective review of medical records.
Participants:
Thirty-six patients (38 eyes) who had undergone EDCR CM for chronic epiphora caused by common canalicular obstruction.
Methods:
Surgical outcomes were evaluated postoperatively by improvement of subjective symptoms and patency of the neo-ostium of DCR on nasal endoscopy.
Results:
Subjective symptoms improved in 81.6% (31/38) after primary EDCR CM and 94.7% (36/38) after revision surgery. In cases of silicone stent intubation, the surgical results were relatively superior compared with patients without silicon stent insertion (83.3% and 75.0%, respectively; p = 0.624). On postoperative nasal examination after primary surgery, the patency of dacryocystorhinostomy site was lower in patients with silicone stent insertion than those without (86.70% and 100%, respectively; p = 0.560), and the patency rate of the canalicular neo-ostium was higher in patients with silicone stent insertion than those without (90.0% and 75.0%, respectively; p = 0.279). There were no serious intraoperative complications except mild punctual erosion (4 patients, 10.5%).
Conclusion:
EDCR CM showed favourable surgical outcomes and few surgical complications. This surgical treatment could be the first-line treatment for patients with distal common canalicular obstruction.
