Ambiguous Role of Stenting during and after Endoscopic Dacryocystorhinostomy

Activity: Talk or presentation typesOral presentation


Otolaryngologist experience with traditional and new method of dacryocystorhinostomy. Comparison of outcomes. In conclusion new method is safe and feasable.

It has been previously established that in endoscopic dacryocystorhinostomy (endo-DCR), stenting is the “gold standard” for preventing rhinostomy closure. The modal standard period between stent placement and evacuation, based on literature review, is three months. To decrease complication risk, it is preferred to evacuate the stent as soon as possible. However, there are still no clear guidelines about post-operative management of stents, although it directly influences outcome of surgical treatment. The aim of this study was to evaluate the potential impact of stenting on outcome in patients undergoing endoDCR.. A retrospective study of patients who underwent primary endoDCR at two medical centres in Riga (Latvia) - “Jugla” and “AIWA Clinic” by the same surgeon between January 2013 and December 2022 was conducted. The indication for surgical intervention in all participants was nasolacrimal system distal obstruction.. In total 272 pts. were enrolled, which were divided into three groups: 66 (24.3%) with the stent for 3 months (control group (I)), 154 (56.6%) - for 1 month (II), 52 (19.1%) without stenting (III). 10 patients had re-operation due to stoma closures: 6 (9.1%), 3 (1.9%) and 1 (1.9%) respectively (p=0.027). The frequency of reoperation due to stoma closure was higher in the control group. This may be connected to the beginning of our endo-DCR practice when we acted according to the “gold standard” and had leaved the stent for 3 months. At the same time, lower technical support and lower experience of the surgeon took place at the beginning of the practice of this surgery.. Reducing of stenting terms or non-stenting showed no worse surgical outcomes than in the control group. The preliminary results have demonstrated that stenting and other endo-DCR factors require further study to improve treatment strategy.
