Nasolacrimal Polyurethane Stent Placement for Epiphora: Technical Long-term Results

Dacryocystostenting: technical and long-term results

“…After this time, there was a progressive increase in the number of non-functioning stents up to 13% patency after 4 years. Our data disagree with those reported in the literature, showing a higher rate of stent occlusion [30][31][32][33][34].…”

“…Dopo tale periodo, nella nostra casistica, si assiste ad un progressivo aumento degli stent non funzionanti fino ad arrivare al 13% di pervietà dopo 4 anni. I nostri dati si discostano da quelli della letteratura, evidenziando una maggiore incidenza di occlusione [30][31][32][33][34]. Il dacriocistostenting, secondo la nostra esperienza, mostra una percentuale di occlusione molto elevata a lungo termine e non può pertanto essere proposto come alternativa all'intervento chirurgico.…”

Bacterial Spectrum and Antimicrobial Susceptibility Patterns in Acquired and Connatal Lacrimal Duct Stenosis

“…In persistent cLDO, high-pressure nasolacrimal duct probing with subsequent silicone-tube intubation is recommended, while in aLDO, external or endonasal dacryocystorhinostomy and endoscopic dacryoplasty of the nasolacrimal duct system are widely used. The restenosis rate is about 5-25% in aLDO [9][10][11] and 10-15% in cLDO. 10,12,13 The persistence of the bacterial inflammation resulting from an ineffective postoperative treatment may be one major reason for operative failure.…”

Polyurethane stents for lacrimal duct stenoses: 5-year results

“…Comparing the results of all existing studies the conclusion met in the present study could almost be expected, however failed to be proven so far. The longer the follow-up period (6 months, 1 year, 2 years) [8,9,11,12,13,21,28,29] the lower was the success rate or the rate of patent stents. The early postoperative [2] to early medium-term [3] results of our patients (i.e.…”

“…Other authors found similar or worse results. Pabon et al [12] reported a stent patency of 72% in a follow-up period of 1 year, and Schaudig and Maas [21] found a success rate of 50% for the same period.…”
