Clinical study of two kinds of lacrimal duct catheterization in the treatment of lacrimal canalicular rupture in children / 国际眼科杂志(Guoji Yanke Zazhi)

@#AIM: To explore the usefulness of RS-type lacrimal drainage tube versus double silicone tube for children's lacrimal canaliculi rupture.<p>METHODS: A retrospective analysis from August 2016 and July 2018 were taken. Totally 37 children(37 eyes)of lacrimal canaliculi rupture were enrolled in the study and divided into two groups according to admission time sequence: treatment group(20 eyes)and control group(17 eyes). The treatment group was treated with RS-type lacrimal drainage tube. The control group underwent the implantation of double silicone tube and their efficacy was analyzed.<p>RESULTS: It was significant difference that the epistaxis rate between the treatment group and the control group, which was 0% and 100%. The effective rate was 95% and 88%, respectively, for the treatment group and the control group, the difference between the two groups has no significant(<i>P</i>=0.584). And the postoperative complication rate was 5% in treatment group, 12% in control group respectively, there was no significant statistical difference between the two groups(<i>P</i>=0.584).<p>CONCLUSION: The implantation of the RS-type lacrimal drainage tube can effectively prevent epistaxis, is safe and simple, easy to operate and extubate easily with good clinical effect in the treatment of lacrimal canaliculus fracture in children. So it can be widely carried out in basic hospitals.

Surgical Outcomes of Endonasal Revision Surgery for Failed DCR According to Number of Silicone Tubes

PURPOSE: To evaluate the causes of failed dacryocystorhinostomy (DCR) and the effects of transcanalicular diode laser-assisted endonasal revision surgery according to the number of silicone tubes. METHODS: Sixty-seven patients (70 eyes) who underwent revision surgery using transcanalicular diode laser for failed primary endonasal DCR at Sungmo Eye Hospital between March 2007 and December 2012 were studied retrospectively. The causes of failed DCR and the time of recurrence were evaluated. The revision surgeries were endoscopic removal of granuloma and membrane and synechiolysis with intubation of 1 or 2 silicone tubes. We compared the results of revision surgery with 1 silicone tube and 2 silicone tube intubations. RESULTS: Recurrence occurred after a mean duration of 4.6 months following the first DCR. The causes of surgical failure were granuloma (35 eyes), membranous obstruction (23 eyes), synechia (7 eyes), and functional obstruction (5 eyes). We performed revision surgery with 1 silicone tube intubation in 45 eyes (group A) and 2 silicone tube intubations in 25 eyes (group B). The final success rates in groups A and B were 75.6% (34/45) and 84% (21/25), respectively (chi-square test, p = 0.828). CONCLUSIONS: Transcanalicular diode laser-assisted endonasal revision surgery with 2 silicone tubes is not recommended.

Long Term Effect of Double Silicone Tube Intubation for Acquired Nasolacrimal Duct Obstruction

PURPOSE: To evaluate the long term effectiveness of double silicone tube intubation in the treatment of acquired nasolacrimal duct (NLD) obstruction. METHODS: The authors treated 68 eyes of 40 patients with acquired NLD obstruction. The resolution of preoperative symptoms and signs of NLD obstruction was evaluated 18 months after the operation. RESULTS: The mean age of patients was 64.7 years and the mean follow-up period was 24.91 months. The symptoms and signs of NLD obstruction were improved in 85.29% of the patients. The partially obstructed group showed a higher success rate (89.29%) than the completely obstructed group (50.0%). A prolapse of silicone tubes to the ocular side was observed in 2 eyes, and 2 eyes had inflammatory signs after the procedure. CONCLUSIONS: Double silicone tube intubation is an effective primary therapy with NLD obstruction, especially for patiensts with simple partially obstructed NLD instead of dacryocystorhinostomy.

Effects of Double Silicone Tube Intubation for Nasolacrimal Duct Obstruction in Adults

PURPOSE: To evaluate the effectiveness of double silicone tube intubation in the treatment of nasolacrimal duct (NLD) obstruction in adults. METHODS: We treated 159 eyes of 159 patients with NLD obstruction. The resolution of preoperative symptoms and signs of NLD obstruction was evaluated two months after the removal of the silicone tubes. RESULTS: The mean age of patients was 57.9 years and the mean follow-up period was 8.5 months. The symptoms and signs of NLD obstruction were reduced in 85.6% of the patients. The partially obstructed group showed a higher lacrimal patency rate (93.0%) than the completely obstructed NLD group (82.7%). There was no discomfort due to the double silicone tubes. There was a punctal slit in 13 eyes, prolapse of silicone tubes to ocular side in 5 eyes and 3 eyes had punctum to punctum adhesion after the procedure. CONCLUSIONS: Double silicone tube intubation is an effective therapy in adults with NLD obstruction, especially for those with partially obstructed NLD. Indications were seen that these tubes keep greater dilatation of the NLD.
