This study shows that using inexpensive polypropylene sutures as stents in endoscopic dacryocystorhinostomy (DCR) is effective. This low-cost method offers a promising alternative to silicone stents for treating blocked tear ducts.
Area of Science:
- Ophthalmology
- Otorhinolaryngology
Background:
- Endoscopic dacryocystorhinostomy (DCR) is a common surgical procedure for lacrimal apparatus obstruction.
- Common causes of DCR failure include common canaliculus obstruction and rhinostomy site closure.
- Silicone stents are frequently used but are expensive and not always accessible.
Purpose of the Study:
- To evaluate the clinical efficacy and outcomes of using polypropylene (Prolene) sutures as stents in endoscopic dacryocystorhinostomy.
- To assess polypropylene as a cost-effective and readily available alternative to silicone stents.
Main Methods:
- Fifty-one endoscopic DCR procedures were performed between July 2013 and December 2014.
- 3/0 Prolene sutures were inserted from the lower punctum to the neo-ostium after creating an aperture in the lacrimal sac.
- Prolene stents were left in place for 3 weeks, with patients followed up for 3 months.
Main Results:
- The study included patients aged 41-60 years (47%) with a female preponderance (64.7%).
- A high success rate was observed, with 47 patients (92.2%) achieving very good results.
- Two patients (3.9%) developed granulomas requiring revision surgery; 2 patients were lost to follow-up.
Conclusions:
- Stenting with polypropylene sutures is an easy, safe, effective, and low-cost modification for endoscopic DCR.
- Prolene sutures offer a promising and accessible alternative to silicone stents, particularly in resource-limited settings.
