Endoscopic dacryocystorhinostomy with canalicular marsupialization in common canalicular obstruction

Abstract

ObjectiveTo evaluate the surgical outcomes of endoscopic dacryocystorhinostomy with canalicular marsupialization (EDCR CM) in common canalicular obstruction. DesignRetrospective review of medical records. ParticipantsThirty-six patients (38 eyes) who had undergone EDCR CM for chronic epiphora caused by common canalicular obstruction. MethodsSurgical outcomes were evaluated postoperatively by improvement of subjective symptoms and patency of the neo-ostium of DCR on nasal endoscopy. ResultsSubjective 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%). ConclusionEDCR 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.
