Assessing the Necessity of Stenting during Endonasal Dacryocystorhinostomy

Ekaterina Kondratishko


Purpose

Endonasal dacryocystorhinostomy (endoDCR) stands as a pivotal surgical intervention for distal nasolacrimal duct obstruction (NLDO), with stenting serving as a standard measure to prevent rhinostomy closure. Typically, stent is retained for approximately three months, yet early removal is favored to mitigate risks such as infection, granulation formation, and lacrimal point laceration. Despite its crucial role in surgical outcomes, the post-operative management of stenting lacks definitive guidelines and empirical evidence. This study aims to scrutinize the treatment outcomes of endoDCR patients with varying stenting protocols.


Methods

This cross-sectional study enrolled adult patients suffering from chronic epiphora (>6 months), exhibiting evidence of distal NLDO, and undergoing endoDCR at Riga Medical Center between 2013 and 2023. Preoperatively, patients with exacerbated chronic dacryocystitis received systemic/topical antibiotics and non-steroidal anti-inflammatory drugs (NSAIDs). The investigation focused on assessing the long-term outcomes of three distinct groups: Group I (control) with a standard stenting duration of 3 months, Group II with an abbreviated stenting period of 1 month, and Group III without stenting altogether.


Results

Notably, seventy-six patients underwent concurrent nasal surgeries to augment endoscopic access to the tear sac. Interestingly, the reoperation rate due to stoma closure was observed to be higher in Group I, presumably attributable to the initial adherence to the gold standard, coinciding with diminished technical support and surgeon experience.


Conclusion

Preliminary findings suggest that stent utilisation does not exert a significant influence on surgical outcomes. However, the nuances of stenting conditions in endoDCR, coupled with other pertinent variables, underscore the imperative for further prospective investigations within our scientific cohort, aimed at refining and optimising clinical practices.
